| Abstract : | We present the spectroscopic observations of few Beta Lyrae type binaries observed from HCT , IIA in the year 2021 . Spectroscopic data were collected at different orbital phases for selected systems in order to explore the relation between EW of H alpha and orbital period of the respective systems. We find that there is correlation between EW and orbital period that can used to study the evolution of the stars. Further more we performed light curve solutions and constrain various binary element parameters. We also study the correlation between various binary elements and EW of H alpha line. |
