Reply to comment by 4thDevilsAdvocate in [NASAWebb] TRAPPIST-1 b: We give it a one (M-dwarf) star review; it lacks atmosphere. Webb found the dayside temperature of this rocky exoplanet to be about 450º F (227º C) — suggesting it has no significant atmosphere by Easy_Money_

mercury is almost twice as hot.

it's trappist d we care about anyway

Sure, but in the model of "it's a barren, atmosphere-less planet close to its parent star", it's quite like an Earth-scale version of Mercury.

Trappist-D, -E, and -F might all be habitable. E has the best chance.

Well, the lack of atmosphere on a planet we expect to have the strongest outgassing (due to intense tidal/induction heating) to replenish anything lost in the wind is telling things about the other worlds. Still - fingers crossed for results on TRAPPIST-1 g which are apparently in the works right now.

I mean it is one planet out of quadrillion but yes I get what you're saying it's making people afraid that the most abundant planets around red type Stars where most life in the universe will have a chance to live for the longest period of time it's scaring people that the Stars may be violent and may strip atmosphere and there may not be as much chance for life in the universe as a result but still I would caution that it's literally one planet
