Abstract:
Photoelectric observations of the star HD 200925 in the standard UBV system have been secured and analyzed. The period is determined to be 0. ͩ 267394. From the period and shape of the light and colur curves, the star HD 200925 appears to be a dwarf Cepheid. The physical parameters have been derived. The mass derived for this star is found to agree well with the value inferred from the evolutionary tracks. The star appears to be a post-main sequence star in the hydrogen shell burning stage of evolution. The spectral class, fro this star, is assigned to be F2 III.
