No Heliosphere Bow Shock Sun has a Wave Motion in Water

[quantauniverse]

McComas at IBEX has found that there is not a bow shock ahead of the sun's heliosphere. The sun's heliosphere moves in interstellar space like the bow of a boat through water, as a gentle WAVE, not as a bow shock. A wave motion for the sun's travel, cannot but inspire the Electric model of the sun. Clearly what they call a wave, is actually an electromagnetic wave of motion, caused by the far stronger interstellar magnetic field interacting with the solar system bubble and ribbon. McComas says all their research used models with a bow shock, which means their results are worthless and incorrect. Why believe there upcoming explanation, when they say "It's too early to say exactly what this means?" What it means is the electric sun model is correct. Bow shocks are called sonic booms to explain supernova winds traveling near relativistic speeds. other stars are seen to have bow shocks, but the gravity explanation is wrong. Winds are magnetized plasma particles, and behave by electromagnetic forces.

So, how is that different from a "bow shock", such as Earth's".

[jjohnson]

First, a shock is a region where there is a relatively sudden change in pressure created when a body moves through a matter medium at a velocity greater than that of the transmission speed of pressure waves in the medium. That can be where the wave changes to supersonic, or from supersonic back to subsonic. The term sonic is typically used, even in the plasma because it originally came from investigations of the speed of sound in air, and then was generalized to gases, liquids and solids. Plasma wave velocities came later, but the name has stuck, whether or not audible "sound" is involved.

If one examines a single body moving at supersonic speed relative to its surrounding medium, note that there are always two shockwaves. The bow shock occurs at the front or leading edge, where the medium is highly compressed and moves at supersonic speed relative to the moving body. Then the trailing shock occurs, when the body has moved on past the local volume of the medium and the medium's velocity relative to the moving body reverts to subsonic. The intensity of the shock wave decreases with distance from the moving body. This is a bulk flow situation; a proton moving through a medium of matter does not create shockwaves, although it can have near misses and collisions. It s scale is too small to have "fluid-like" interaction with a medium. If its medium is actually the "neutrino sea" or Bengt Nyman's tiny particle medium consisting of "sii", which is similar, perhaps there could be such an interaction, but we have no evidence of it, and how things work mechanically at Planckian and smaller scales is not well known except statistically.

Magnetic fields can exert pressure (i.e., force per unit area) so plasmas can have pressures involved with them that are different from thermal or physical particle collisions. Thus, the conditions are right for the Earth and its co-moving magnetosphere moving relative to the solar wind (the interplanetary medium) to set up conditions where a shock wave can be formed., both a bow shock around the "front" part of the megnetosphere, and a trailing shock which occurs aft in the "magnetotail" region of the magnetosphere.

It is being discovered that the larger analog, the heliosphere around the Sun, is not moving fast enough through the plasma interstellar medium beyond, or the density of the interstellar medium is not high enough, for a similar shock wave to form. That has come as a surprise as it counters the prevailing predictions of the scientists dealing with such questions and models.

okay....

Magnetic fields can exert pressure (i.e., force per unit area) so plasmas can have pressures involved with them that are different from thermal or physical particle collisions.

This is assuming that Magnetic fields are not particles. And of course magnetic effect "shock wave" would look different because of the additional interaction and the density of the medium.

McComas says all their research used models with a bow shock, which means their results are worthless and incorrect.

It is their understanding of "bow shocks" in space that is incorrect, because they are not factoring in the magnetic effect. The so called "bow shock" of Earth's is probably more magnetic interaction, which is matter interaction, but appears to be a bow shock. A bow shock forms in a dense medium, such as on Earth, not in the sparcness of space. What is being seen is probably energy being pulled from the eather by colliding magnetic effects, and being expressed as magnetic effect. But, if it looks like "bow shock", it must be...

You're a word smithe...come up with a more appropriate name for these "waves and bow shocks" , seen in space.

I'm no word smith, but here's an explanation from Alfvén's book, Cosmic Plasma, 1981, Kluwer, in Chapter III, Circuits. In III.6 The Magnetospheric Circuit, here's an interesting quote about the shock front part of Earth's magnetosphere.

In the first approximation, the solar wind near the equatorial plane will experience a decreasing magnetic field when it approaches the neutral line. When the magnetopause develops, the magnetic field in front of it will increase. The result is a slowing down of the solar wind drift, which is accompanied by an inertia current opposite to the magnetopause current. The situation is analogous to the case treated in model (c) of III.1.3. A plasma [the solar wind] approaching an obstacle (in this case, the magnetopause) is stopped and deviated, not directly by the obstacle, but by the electric field it generates in the approaching plasma. As long as the magnetic field perturbation deriving from this inertia drift is negligible, the current is distributed over a layer of considerable thickness (Alfvén, 1955; because of the reversed interplanetary field the sign of the current in this paper should be reversed). When the plasma density is so large that the inertia current greatly disturbs the magnetic field, the current layer is contracted to a thin sheet. This is identical with the 'shock front' derived by the hydromagnetic approach. Our model predicts that if the solar wind flow is very low, there should be a distributed current instead of a shock.

There is more, but here is Figure III.1(c), in which a plasma beam is incident on a conducting plate. The description tells what happens with low plasma flow rates, and that the deviation is not due to the physical process that occur with bodies in non-ionized fluids.

If there's no bow shock out at the heliopause as the solar system moves through the interstellar medium, perhaps it's because its effect on the interstellar inertia drift is negligible and the current layer at the heliopause remains thick.

I always think I will stop being surprised by how much is simply MADE UP in our science textbooks.
Does no one check these things? If it would not greatly depress me, I would like to put together a book of "scientific truths" that were subsequently found untrue. With the history of dead "truths" strewn out behind us, why do we scientists continue to strut and bluster? How many of our existing truths have never been checked?

In the latest twist in the story, the craft seems to be traversing an unexpected ‘dead zone’. This week, Robert Decker, a space scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, and his colleagues report1 in Nature that at Voyager 1’s current location, some 121.6 astronomical units (18.2 billion kilometres) from the Sun, the average velocity of solar particles has dropped to nearly zero. (Voyager 2, which is about 3 billion kilometres closer to the Sun and moving in a different direction, has yet to detect the same reduction in velocity.)

Decker’s team first reported2 the change last year, when it had measurements of the particles’ velocity only in the radial direction, outwards from the Sun. At the time, the team thought that the change was a sign that the craft was nearing the heliopause, where solar particles are expected to collide with powerful winds generated by supernovae that exploded some 5 million to 10 million years ago. The collision would force the solar particles to stop moving outwards and push them sideways, like a stream of water hitting a solid surface.

To test the idea, engineers commanded Voyager 1 to roll on its side seven times, so that its instruments could record particle velocities along a line perpendicular to its course. Given that sending a command to Voyager 1 now takes 17 hours, and that the spacecraft’s transmitter runs at 23 watts — about as powerful as a refrigerator light bulb — such communication is a feat in itself. The researchers were astonished to find that the particles had zero velocity in this polar direction, too — indicating that they were almost stationary rather than being buffeted by stellar winds. That cannot happen at the heliopause, says Decker. “We therefore conclude … that Voyager 1 is not at the present time close to the heliopause, at least in the form that it has been envisioned,” the team writes1.



Decker and his colleagues now think that since 2010, when the craft first recorded a velocity drop, it has been in an antechamber to the heliopause, at least 1 billion kilometres thick. Why the particles are becalmed remains a mystery, says Stamatios Krimigis, a space scientist at Johns Hopkins and a co-author of the paper. This leaves theorists in a bind. “There no longer exists any guidance on what constitutes getting out of the Solar System and into the Galaxy,” says Krimigis

Maybe you'll like these:

The Ulysses spacecraft detected regions where the predominant fast solar wind encounters slower moving solar wind ahead. These “compressed” regions are referred to as “co-rotating interaction regions” (CIR's) because they co-rotate with the Sun.

… it is the tilt of this axis relative to the Sun's rotation axis which causes alternating slow (low-latitude) and fast (high-latitude) solar-wind streams to sweep over an observer in the ecliptic. Because of the radial outflow of the solar wind, the fast streams eventually run into the slower wind ahead, forming so-called 'co-rotating interaction regions' (CIRs). These are regions of compressed solar-wind plasma, which, as the name suggests, co-rotate with the Sun. At distances beyond 1 AU, CIRs are often bounded by forward and reverse shock waves. As will become apparent, the investigation of CIRs themselves, and their influence on the energetic particles and cosmic rays that populate the heliosphere, forms a major theme in the scientific output of Ulysses.

(…)

Surprisingly, Ulysses discovered that the recurrent effects in energetic-particle and cosmic-ray intensity extend to much higher latitudes than the CIRs themselves. Under the influence of the magnetic configuration of the Sun, the angle between the Sun's rotational and magnetic axes changes with the solar cycle. Near solar minimum, the magnetic and rotational axes are nearly aligned, so that the CIRs are restricted to relatively low heliographic latitudes (typically less than 30 degrees).

As shown in Figure 4, the series of recurrent increases and decreases starting at low latitudes clearly extends to regions far beyond the latitude range of the CIRs or their associated shocks. – " The Heliosphere in Perspective - Key Results from the Ulysses Mission at Solar Minimum

The shock waves and associated structures of CIRs are important in numerous ancillary ways in the solar wind. For instance, CIRs dissipate the energy in fast streams by slowing and heating the plasma, while the magnetic compression regions and turbulence associated with shocks can scatter cosmic rays. Moreover, particles can be accelerated at the CIR shocks. The shocks and most of the plasma structure of CIRs are merged together and primarily smoothed out beyond about 20 AU. Only the magnetic compression regions tend to persist into the outer heliosphere beyond 20 AU. – “Co-rotating Interaction Regions: interactions between fast and slow streams”

Notice (broadly) where the CIR’s generally form within the framework of the slow solar wind here, these “CIR”s can also reverse inject suprathermal sunward bound electrons:

Using ACE and Genesis data, suprathermal electron measurements within high-speed streams and their associated corotating interaction regions (CIRs) have been analyzed. Enhanced fluxes of sunward streaming suprathermal electrons are consistently observed following the passage of a corotating interaction region (CIR) over spacecraft at 1 AU. A backstreaming electron beam, produced at the CIR, is observed whether the CIRs are bounded by reverse shocks or reverse pressure waves. Because an antisunward directed electron strahl distribution is also normally present, electron counterstreaming results. Counterstreaming following CIRs can last for more than 2 days, after which time a 1 AU spacecraft is magnetically connected to a CIR at 3–5 AU. Although electron counterstreaming is frequently associated with closed field lines of interplanetary coronal mass ejections (ICMEs), electron counterstreaming associated with CIRs occurs on open field lines. Occasionally, electron counterstreaming associated with CIR-produced suprathermal electrons is also seen within the slow wind preceding a CIR. In each such case observed the counterstreaming lasted less than 1 day. – “Suprathermal electrons in high-speed streams from coronal holes: Counterstreaming on open field lines at 1 AU

The beams result from electrons that are energized at the shocks and leak out of the CIR into the upstream solar wind. That leakage produces field-aligned electron beams directed away from the CIR. The diagram above shows schematically the field line geometry of a CIR, and illustrates that CIR-leaked electrons move sunward for both the forward and reverse shock cases. – “Suprathermal Electrons in High-Speed Streams: Counter-Streaming on Open Field Lines at 1 AU

They're like amorphously 'mobile' double layers that can accelerate electrons in BOTH directions within the slow solar wind. Makes me wonder if they make any additional contributions when comets suddenly brighten; then fade.

It could also be because the Sun has a higher voltage than the Earth, and therefore is able to deflect and control the galactic medium better, whereas with the Earth less power to "part the waves" means it must plow "head on" so to speak.

Oh, and Solar, those outer co-rotating regions are probably the Sun's Van Allen radiation belts. As NASA put it, blazing across the sky. Will get link.

[viscount aero]

I'm no genius, but it seems to me that unless there is a magnetic/eletrical/'polar' resistance (like 2 magnets placed together with the same poles next to each other, repelling each other) there will be no "bow shock" to speak of --ever encountered.

Also, unless, too, there is a similar interaction of plasma that we see in Earth's aurorae, where the ionization of the Solar plasma occurs as it impinges against the Earth's own ionosphere, there will not be a "bow shock." One would expect to see a "Heliosheath aurorae" region. But no such thing seems to be afoot.
