Atomic Diffusion in Stars

diffusion, appropriately modified for convection. This is the time it takes for a star to come into and maintain thermal steady state, e.g., for the energy generated.

Atomic diffusion. Atomic diffusion is a physical process acting at a microscopic level that can produce macroscopic segregation of atomic species in a non-isotropic medium. It is a non-standard transport process because no advective term appears in the basic equations describing it. To simplify the problem, one can say that in a star, atoms of a given species may on average be pushed upwards Slowing down atomic diffusion in subdwarf B stars: mass ...
