Inhaltsangabe:
- The present paper is devoted to studying the variability of the $γ$ Cas type star SAO 49725. Both the optical and X-ray spectra of the star are analyzed. Variability of line profiles in the spectra of SAO 49725 was discovered on short (70-223 minutes) scales. Based on the TESS photometric light curves of SAO 49725 the regular variations of light curves are detected with a period of 1.1989 days identified as the rotation period of the star. The pattern of photometric variability in SAO 49725, as observed by TESS, varies significantly across different epochs. The TESS components of the SAO 49725 light curves with periods of $\sim3-21\,$days may be instrumental.
