Astrophysics and Space Science Aims and scope Submit manuscript

Abstract

Component frequencies of FM Com were analysed using 43 hrV band photoelectric observations. Both the usual Fourier and the autoregressive extrapolation techniques applied to the closely spaced nights of observation yielded variable frequency patterns. Comparison of the observed and synthetic light curves calculated by the two frequencies obtained by analysing a previously obtained compact data segment supports the suggestion of this star's nonstationary light variation.
