A deep dive into the interior of red dwarfs

Sept. 8, 2022- 
Red dwarfs are the most abundant stars in the Milky Way, making up 70% of all stars. But the physics of their interiors is not well understood. Heat is generated in the core and travels outward to the surface, but it is not clear whether that process occurs via radiation, convection or a combination of the two. The key factor determining whether red dwarfs are radiation- or convection...
