On the DB gap of white dwarf evolution: effects of hydrogen mass fraction and convective overshooting
arXiv:0911.2949 · doi:10.1088/1674-4527/10/3/008
Abstract
We investigate the spectral evolution of white dwarfs by considering the effects of hydrogen mass in the atmosphere and convective overshooting above the convection zone. We notice the importance of the convective overshooting and suggest that the overshooting length should be proportional to the thickness of the convection zone to better fit the observations.
