Parameter determination of a binary star system

The work focuses on determining the physical parameters of binary star systems, specifically applying algorithms to the system UV Leonis.

The study utilizes IRAF (Imaging Reduction and Analysis Facility), a specialized software program for the analysis of astronomical data.

The results confirm that both components of the UV Leonis binary system are main-sequence stars with a spectral type similar to the Sun.

Based on the sinusoidal shape of their radial velocity curves, both components are concluded to be nearly spherical.

The masses of the stars in the UV Leonis system were spectroscopically determined here for the first time.

The calculated distance to UV Leo is consistent with the trigonometric parallax from the Hipparcos mission, but with a smaller error bar.
