18. Model Atmospheres for Hydrogen-Deficient White Dwarfs
Published online by Cambridge University Press: 14 August 2015
Abstract
The determination of atmospheric parameters for non-DA white dwarfs is investigated with the computed helium-rich model atmospheres by Bues (1970). Only poor predictions are possible from UBV colors alone for DB and DC stars. From uvby colors a determination of effective temperature is possible within 1000 K. Profiles of lines in different parts of the spectrum are necessary for better results.
A deficiency of metal abundances for the cooler non-DA stars is obtained.
