摘要

•We present the analysis of spectroscopic and photometric observations of BO Arietis.•Complete light curves were observed and new times of minima were calculated.•The period changes in Observed–Calculated (O–C) diagram were analyzed.•The orbital and physical parameters of the system were obtained.•Our model describes BO Ari as an A-type overcontact system.
