Please stay away from Gliese 1132

With the Alfvén constraint blasting havoc in water-poor planets, "Andrei" is bringing Gliese 1132 b. Suspected is vulcanism.

I'd actually already looked at this when Wiki cared, in 2021. The one post-Wiki dedicate paper which Google Scholar coughs up is this 2023 paper. This covered two transits via Webb, one with vapour and N2O, as we'd thought in 2021... and one with, nothing. Stellar contamination is cited.

This points to starspots on GJ 1132. Where are starspots, we must fear flare. The planet is occasionally irradiate - like poor blasted Proxima. And at 19 times Earth flux... okay, let's consider how the darkside looks.

GJ 1132 b and c are not particularly resonant; 11:2, feh. They are however eccentric and c weighs in over 2.64 M🜨. b should be volcanic, as sometimes perhaps detected. These gasses could be temporary spurts from volcano on the starside. I'm not even sure something this eccentric must be 1:1 locked, it could be 2:3 or 3:2 like Mercury.

Eitherwise, b looks horrible. Atmo may well be as sporadic as the radiation it gets, blasted out by flare, just to replenish it.

Then there's c at 1.9 flux... like Venus. As a superterrene there's no good core (Venus isn't even superterrene, and has no good core). This also looks horrible, whether its atmo is blasted out or no.

I'm not taking my starship near this place. Sorry, Andrei.
