摘要: Outer convection zones of white dwarfs in the range 5800 K≤T eff≤30000 K have been studied assuming that they same chemical composition as determined by Weidemann (1960) for van Maanen 2. Convection is important all these stars. In T eff< 8000 adiabatic temperature gradient strongly influenced pressure ionization H, Hei and Heii which occurs within zone. Partial degeneracy also important.
