Abstract

The boundary convection zones of hot helium white-dwarf stars (WDSs) in the range 17000 K less-than-or-equal-to T(e) less-than-or-equal-to 30000 K are studied. Recently, an anisotropic mixing-length theory (AMLT) which determines the mixing-length parameter locally is applied for the convection zones calculation. Comparing with the calculations by using the (MLT), it is found that maximum velocity decreases appreciably, and the other boundary conditions are affected.
