"For almost a decade, astronomers have tried to explain why so many pairs of planets outside our solar system have an odd configuration—their orbits seem to have been pushed apart by a powerful unknown mechanism. Yale researchers say they've found a possible answer, and it implies that the planets' poles are majorly tilted.

"The finding could have a big impact on how researchers estimate the structure, climate, and habitability of exoplanets as they try to identify planets that are similar to Earth. The research appears in the March 4 online edition of the journal Nature Astronomy.

"NASA's Kepler mission revealed that about 30% of stars similar to our Sun harbor "Super-Earths." Their sizes are somewhere between that of Earth and Neptune; they have nearly circular and coplanar orbits; and it takes them fewer than 100 days to go around their star. Yet curiously, a great number of these planets exist in pairs with orbits that lie just outside natural points of stability.

"That's where obliquity—the amount of tilting between a planet's axis and its orbit—comes in, according to Yale astronomers Sarah Millholland and Gregory Laughlin.

""When planets such as these have large axial tilts, as opposed to little or no tilt, their tides are exceedingly more efficient at draining orbital energy into heat in the planets," said first author Millholland, a graduate student at Yale.

""This vigorous tidal dissipation pries the orbits apart."

"A similar, but not identical, situation exists between Earth and its moon. The moon's orbit is slowly growing due to dissipation from tides, but Earth's day is gradually lengthening.

"Laughlin, who is a professor of astronomy at Yale, said there is a direct connection between the over-tilting of these exoplanets and their physical characteristics. "It impacts several of their physical features, such as their climate, weather, and global circulations," Laughlin said. "The seasons on a planet with a large axial tilt are much more extreme than those on a well-aligned planet, and their weather patterns are probably non-trivial."

"Millholland said she and Laughlin already have started work on a follow-up study that will examine how these exoplanets' structures respond to large obliquities over time."

Yale researchers have 'found' an answer but is it the right answer? What "powerful unknown mechanism" can modify planetary orbits to maintain stable configurations? Tidal or electrical?

Robert is, This was addressed in one of “the electric view” videos on YouTube. And your post helps confirm that idea.

The idea is that if our solar system is strung on a current filament, then planets can orbit in one of those concentric shells, in a nearly circular orbit. It would then have a spin axis aligned to that shell, from which it gets its current. Venus as an example.
A planet that moves in and out of that shell, would have its axis pointed towards that shell. Witness the fact that Earth and Mars at perihelion, have a their north poles tilted away from the sun, while at aphelion, have their north poles tilted towards the sun. That Is, the close correspondence of the winter solstice point in Earth’s north hemisphere, to the perihelion point in Earth’s orbit, can be explained if Earth’s North Pole is tilted towards a constant radius from the sun (one of those cylindrical shells). Mars shows the same relationship exactly.

Sorry, but I can’t find the correct video in the “electric view” video series.

watching (because I want to see this video too)

celeste, your words paint a perfect picture. Thank you.

It is good that they put "super-earths" in quotes because recently it has been provide that they do not exist.

A planet larger than Earth and smaller than Neptune is not an Earth like planet. This size range is inhabited by ocean worlds.

Maybe if there is a complete (thick) water surface that may impact the tilt (orbit dynamics) as well..

I concur. That stage of planetary evolution is composed of ocean worlds. Oxygen and hydrogen are two out of the three most abundant elements in young stars, when they combine they will make lots of left over water. They are volatiles, but the hydrogen bonds will prevent the water from escaping, after the water is formed.

Thick, deep ocean worlds are all over the galaxy. There are "super Earths" though, that are Earth like and more massive than the Earth, but only slightly. When you move up to something that is >2 earth masses you have a water world.
