White Dwarf Pulsation Model
Effective Temperature [K] [20000 - 30000]
Total Mass [M*/Msun] [0.45 - 0.95]
Helium Layer [-log(MHe/M*)] [2.0 - 7.3]
Central Oxygen Abundance [XO] [0.0 - 1.0]
Oxygen transition point [m/M*] [0.10 - 0.85]
This program calculates the theoretical l=1 pulsation periods between 400 and 850 seconds for a DBV white dwarf model of a given temperature, mass, helium layer mass, and internal composition and structure within the parameter ranges shown to the right. Type in values for each parameter and click the "Calculate Periods" button below. It may take a minute or more to perform the calculation, so please be patient.
