热缺氢星MV Sgr的脉动周期

The Pulsation Period of the Hot Hydrogen-Deficient Star MV Sgr

John Percy, Rong Hannah Fu

摘要:

MV Sgr是一颗热的缺氢恒星,经历了R CrB衰退。我们已经使用了自相关分析和傅立叶分析的CCD V测光在AAVSO国际数据库,以确定在这颗星的周期为8.0天,振幅约为0.03马格。的变化是最有可能由于脉动。

英文摘要:

MV Sgr is a hot, hydrogen-deficient star which has undergone R CrB fadings. We have used self-correlation analysis and Fourier analysis of CCD V photometry in the AAVSO International Database to identify a period of 8.0 days in this star; the amplitude is about 0.03 mag. The variability is most likely due to pulsation.
