The effect of 3He diffusion on the pulsational spectra of DBV models
The effect of 3He diffusion on the pulsational spectra of DBV models
Isotopic separation is inevitable in white dwarf stars if our understanding of diffusion is correct.This can have many important, and largely unexplored, astrophysical consequences.Asteroseismology gives an opportunity to investigate this possibility.We first examine the relevant timescales for diffusion in these objects, and compare them to the evolutionary timescales in the …
