Ground based observation of ZZ Ceti stars and the discovery of four new variables
Alejandra D. Romero, L. Antunes Amaral, T. Klippel +7
We perform ground based photometric observations of 22 DA white dwarf stars, 10 already known ZZ Cetis and 12 candidates with atmospheric parameters inside the classical instabilit…
Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
New developments of the ZZ Ceti instability strip: The discovery of eleven new variables
B. G. Castanheira, S. O. Kepler, S. J. Kleinman +2
Using the SOAR 4.1 m telescope, we report on the discovery of low amplitude pulsations for three stars previously reported as Not-Observed-to-Vary (NOV) by Mukadam et al. (2004) an…
Whole Earth Telescope observations of BPM 37093: a seismological test of crystallization theory in white dwarfs
A. Kanaan, A. Nitta, D. E. Winget +3
BPM 37093 is the only hydrogen-atmosphere white dwarf currently known which has sufficient mass (~ 1.1 M_sun) to theoretically crystallize while still inside the ZZ Ceti instabilit…
