# Life forms in brown dwarf atmosphere

Some of brown dwarfs generate the enought amount of heat to warm their atmosphere up to 300 K. This is a condition to liquid water and, possibly, organic life forms.

Is where are a some studies about life forms in BD atmosphere?

• There's a problem of density. Liquid water is quite a bit denser than even very dense gas and to reach that density you'd have to be fairly deep inside the star, which would suggest much higher temperature. It's like the submarine on Jupiter problem. By the time density is equal to water, pressure and temperature are enormous. what-if.xkcd.com/138 Nice idea though, but liquid water is probably unlikely.

• You should make that an answer, @userLTK. – pela Aug 8 '16 at 16:26
• Liquid water doesn't mean ocean. It could be a clouds... Microbes habitable clouds – Y.N Aug 8 '16 at 18:54
• I didn't mean to say it was impossible, only that liquid water is unlikely, but you're right, clouds with some liquid water is possible. – userLTK Aug 8 '16 at 20:00
• I think any answer to this would have to be speculation. – James K Jan 22 '17 at 21:51

Although you might think that Y-dwarfs (brown dwarfs with temperatures $<500$ K) might become cool enough to support liquid water. In fact that does not happen. As discussed by Burrows et al. (2003) and Morley et al. (2014), in Y-dwarf atmospheres, when the temperature becomes low enough for water to condense out of the gas phase ($<375$K), it goes straight to water ice particles.
