BPM 37093: preliminary results from XCOV 16 and XCOV 17.
KANAAN A., NITTA-KLEINMAN A., WINGET D.E., KEPLER S.O., MONTGOMERY M. (The WET TEAM)
Abstract (from CDS):
BPM 37093 is a 1.1 M☉ ZZ Ceti star. This star's temperature (≃11 000 K) and high mass (≃1.1 M☉) imply that it should be crystallized throughout most of its core, the exact fraction depending on its core composition. BPM 37093 is the first object where the results of crystallization theory can be probed observationally. If the star is crystallized its pulsation spectrum should differ significantly from non-crystallized pulsating stars. In this paper we report our preliminary results from the analysis of WET data obtained in 1998 and 1999.
