Can Alpha Centauri Bb have an atmosphere?
It's theorized to have a temperature of 1200 degrees C. That, and being so close to its star, I think would strip away any atmosphere consisting of familiar gases: hydrogen, nitrogen, oxygen, methane. However, can it hold on to heavier substances, which would have gaseous forms at that temperature? What would be some examples?
It's suspected to have a magma ocean. My basic physical chemistry knowledge says that anything that's liquid has a vapor pressure, so would there be some small amount of evaporated silicon dioxide in the atmosphere, if it has one? And therefore would there be lava rain?

It will have an atmosphere, however it will be very thin. Very few gasses, and they would be mostly noble gasses
