摘要:

我们提出了高速光度观测的ZZ Ceti白矮星候选人从光谱调查的明亮DA星从维拉诺瓦白矮星目录由Gianninas等人,以及Limoges等人最近对距离太阳40秒差距以内的白矮星的光谱测量。我们报告了从这些测量中发现的六个新的ZZ Ceti不稳定星和几个光度恒定的DA白矮星,然后我们用它们来修正ZZ Ceti不稳定带的位置。

英文摘要:

We present high-speed photometric observations of ZZ Ceti white dwarf candidates drawn from the spectroscopic survey of bright DA stars from the Villanova White Dwarf Catalog by Gianninas et al., and from the recent spectroscopic survey of white dwarfs within 40 parsecs of the Sun by Limoges et al. We report the discovery of six new ZZ Ceti pulsators from these surveys, and several photometrically constant DA white dwarfs, which we then use to refine the location of the ZZ Ceti instability strip.
