Long Period Eclipsing Binaries V891 Mon and KV CMa

Key Points

The aim is to investigate the mass characteristics of the long-period eclipsing binary systems V891 Mon and KV CMa.
Analyzed spectral data from the echelle spectrograph HRS of SALT.
Used photometric data from ASAS, TESS, and LCO observatory.
Calculated velocity amplitudes to derive masses of components.
Determined the masses of both components of V891 Mon and KV CMa through velocity analysis.
Revealed significant insights into the dynamics of long-period eclipsing binaries.

Abstract

We present the results of a study of long-period eclipsing binary systems V891 Mon and KV CMa. The presented study is based on spectral data obtained at the echelle spectrograph HRS of the Southern African Large Telescope (SALT) and photometric data from ASAS, TESS and the LCO observatory. The calculated velocity amplitudes of both components allow us to determine the masses of both components of the system.
