Study of the \(\boldsymbol{\mu}\) Cet Binary with Speckle Interferometric, Photometric, and Spectroscopic Techniques

Abstract

We present a refined speckle-interferometric orbit of a binary system \(\mu\) Cet, with the main component studied based on the analysis of photometric and spectroscopic data, obtained with the SAO RAS 6-m telescope. The object was initially classified as a giant with chemical composition anomalies. As a result of our analysis, we conclude that the star belongs to the Main Sequence, to the class of non-peculiar stars. Analysis of photometric data from the TESS mission indicates that the main component of the system belongs to the \(\gamma\) Dor pulsators.
