Re: Extreme age?
"I've seen calculations that give a lifetime of 15 *trillion* years for some red dwarves"
That's very true, but only valid for smaller red dwarves. Kepler-438 is supposedly about 0.5 solar masses, so while it'll last longer than our own sun, it will in all likelihood end main sequence and become an intermediate red giant in a few billion years.
Given that Kepler-438b has such a close orbit, once that happens I think it would be fair to describe conditions on the surface of the exoplanet as 'a bit toasty'...
