We are talking about GJ 1132, or Gliese 1132 - this is a single red dwarf star in the constellation Velae: it is located on
In 2015, the planet GJ 1132 b was found on her.It is 1.6 times larger than the Earth, and makes a full annual revolution in just 1.6 of our days. A few years ago, GJ 1132b was found to have an atmosphere. This is interesting, since the planet is extremely close to its star and, according to all calculations, should have lost it long ago.
The authors of the new work offered their explanationTo this phenomenon, they believe that the planet really lost its atmosphere 100 million years ago, and then received a second one, which dissipates, but is constantly replenished from a reservoir of hydrogen in mantle magma.
The planet is of volcanic origin, as it contains anomalously high hydrocyanic acid - up to 0.5%. It is rich in hydrogen, hydrogen cyanide, methane and ammonia.
This second atmosphere occurs both withsurface as well as from inside the planet, so it serves as a window into the geology of another world. There's a lot more work to be done to get a good look at it, but opening this window makes a big difference.
