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