Özet

We present the low resolution (R∼5099) spectroscopy of the eclipsing binary V375 Cas (TIC 326630342) in this study. The low resolution spectroscopic observations of the system were made at the TUBITAK National Observatory using a TFOSC spectrograph in 2020 and 2021. For measuring the radial velocities of both components of the eclipsing binary Gaussian fitting method was used. According to Keplerian orbital solution the spectroscopic mass ratio of the close binary was determined as 0.626 ±0.098. The best fitting orbital elements are a1sin i = 0.0243 ± 0.0018 au, a2sin i= 0.0351 ± 0.0018 au, M1sin3 i = 7.06 ± 0.87 M⊙ and M2sin3 i = 4.42 ± 0.75 M⊙.
