Stellar winds may electrify exoplanets



phys.org said:

The strangest class of exoplanets found to date might be even stranger than astronomers have thought. A new model suggests that they are partially heated by electric currents linked to their host stars. Florida Gulf Coast University (FGCU) astronomer Dr. Derek Buzasi has proposed a model in which electric currents arising from the interaction between the planet's magnetic field and the hot charged wind from the star flow through the interior of the planet, heating it like an electric toaster.

Interesting problem they are trying to solve. My Dark Matter at the center of planets hypothesis fits with the puffier hot Jupiters around magnetically charged sun's with extra energy from dark matter tidal interactions imv. [sorry WD, I see it everywhere]

One problem scientists have had in understanding the hot Jupiters is that many are inflated to sizes even larger than expected for planets so close to their stars. Explanations for the "puffiness" of these exoplanets generally involve some kind of extra heating for the planet. Proposed sources for the extra heat have included tides and interactions between the high-speed winds and magnetic fields expected on these planets, but none of these models successfully explains the observation that more magnetically active stars tend to have puffier hot Jupiters orbiting around them.

The object, known by the locals as "Bicho Voador" (Flying Animal), or "Bicho Sugador" (Sucking Animal), has the shape of a rounded ship and attacks people in isolation.

The problem is that you are the only one that does. A hypothesis with no supporting evidence is a hypothesis with no scientific credidibility (not that it stops you hijacking thread after thread).

The idea of Jupiter's 100ky cycle being responsible for extra tidal forcing to explain the ice age paradox has been forwarded to Prof Maslin, the climatological consultant for the latest BBC series 'Ice Age Giants' by the producer Mags Lightbody. So she was sufficiently impressed by my out-of-the-box left-field thinking. I'm not overly surprised that anyone on this forum doesn't share the same open-mindedness unfortunately.

My explanation for the extra puffiness in exoplanet Jupiters *isn't* extra heating but extra internal convection due to a new interplanetary force.  The idea of a star's Coronal Mass Ejection interacting with a planet's magnetic field has implications for the Earth and apparent increase in aircraft incidents during the last bought of CME's just a month or so ago.
