摘要
介绍中法双方分别于１９９５年和１９９７年对ＤＡ型脉动白矮星Ｇ２５５—２进行的两次高精度的光电测光联合观测．在仔细的数据处理之后进行了多重频率脉动分析，得到了该星的本征脉动模式．同时，结合ＤＡ型脉动白矮星的理论模型进行了初步的星震学分析．
n this paper, we publish the Chinese-French bi-site high-accuracy photoelectric observations of the DA type pulsating white dwarf G 255-2made in 1995 and 1997. After carefuldata reduction, we make a multi-frequency analysis, and determine its eigen frequencies andmodes. In connection with the theoretical model of white dwarfs, we make a preliminaryastro-seismological analysis.
