"Hot Jupiters" around red giants

Post by Lazarus on 14th July 2012, 2:18 pm

What happens when a star becomes a giant and temperatures increase on orbiting gas giant planets? Possibilities of carbon-rich atmospheres from accretion of solar wind, but different wind patterns to tidally-locked hot Jupiters.

Would be interesting to simulate what happens after the peak temp to the moons of this new hot planets. Especially to Europa and Titan

There's actually a paper that talks about the outward migration of our solar system's habitable zone once our sun becomes a red giant. Interestingly enough, the paper suggests that the HZ will move out to Triton and beyond, possibly making Triton, Pluto-Charon, and Kuiper Belt Objects habitable environments.

The paper is "Delayed gratification habitable zones: when deep outer solar system regions become balmy during post-main sequence stellar evolution" by S. Alan Stern

Unfortunately , the article is not freely avaiable , only the abstract in pubmed.

How long would be this DGHZ in place ? some tens of milions of years or so? I don't think that would make for a viable evolutionary enviroment. Not even seeded from the inner planets eyecta.
