Take that you "m dwarf planets have to be dry" types:
phys.org...
yup. geochemistry babe. it's the other other other white meat.
And this article has some relation to tidally locked planets as might be found in the life zone of M dwarf stars. the right conditions can prevent the boil freeze double whammy

Ah, beat me to it!
For me, the jury is out. Until we have a good survey of nearby M-Dwarf planet's atmospheres we won't be able to say for certain.
I would not be shocked if we find quite a few covered in shallow seas of water.
But I also would not be shocked if all we came across were arid desert planets.
I suspect the truth will lay in the middle of those, planets with water vapor and a density that indicates that at least part of the the planet is liquid water.
Bring on TESS, bring on JWST!

when you ask them stuff could you ask about the recent discovery of water at the mantle core boundary that is a bout 400 percent or so of the water we thought earth had.
i mean it may have implications about water retention given the pressure and temperature there.
also please ask them what effects the extreme longevity of red dwarfs would have. some of these things might just be first generation stars. they really can live that long. during that time a lot of stuff can happen. its like comparing the stuff an infant has seen to the stuff a centurnarian has seen.
i know the arguments they made but something about them just doesn't make sense. i cannot help but think it's over simplified.

not to be funny but isn't sol classified as a yellow orange dwarf star?

Necroing because this is the same sort of reasoning applied to another class of star system
phys.org...
Tau Ceti has planets with possibly two in the life zone. this article starts of by saying one of them probably isn't in the life zone and the other has only been in the life zone for 1 billion years so there is likely no chance of intelligent life or civilization.
Yeah but if you want to colonize a garden planet, -that is impossible to ethically do if there are already intelligent occupants. So in my view that makes Tau Ceti more attractive; not less.
Finding beings like us is not the only reason to go out there and it is unlikely that that is even the best reason to go out there.
