Stealing Hot Gas from Galaxies

Stealing Hot Gas from Galaxies

The evolution of a galaxy is strongly dependent upon the environment the galaxy lives in. Galaxies moving through galaxy groups and galaxy clusters can get stripped of their gas that would otherwise be used to form stars. Today’s astrobite discusses simulations of the stripping and removal of the hot, gaseous coronae that surround galaxies.

How do M-dwarf Stars Measure Up?

How do M-dwarf Stars Measure Up?

Very low-mass M-dwarfs are a missing link in our theory of stellar interiors. Stars this small probably have fully convective interiors, but we don’t have a complete understanding of how that affects global properties like radius or temperature. It’s important to get right, if for no other reason because lots of exoplanets orbit M-dwarfs.
