Abstract

Two sets of available photoelectric photometric observational data of the close binary system BV Eri were analyzed with the recent Wilson-Devinney synthetic light curve program. The new absolute parameters of the system were also derived by combining the photometric solutions with the spectroscopic material. The research suggests that BV Eri is a B-type contact binary system, and mass from the primary component is transferring to the secondary component. It may be concluded that BV Eri is a good example following the TRO theory.
