The ZZ Ceti instability strip revisited.

KOESTER D. and ALLARD N.F.

Abstract (from CDS):

Empirical location of the ZZ Ceti instability strip, as well as atmospheric parameters of individual objects, is extremely difficult to determine, and the literature values of Teff often differ by 2000 K. For optical spectra, very small systematic errors of observations or models have a large influence on the result. In the UV the situation is slightly better, but the spectra with some certainty can provide only a relation between Teff and log g. All literature values, that rely on spectroscopy only, are unreliable; accurate determinations require the use of additional constraints like parallaxes, V magnitudes or gravitational redshifts.
