Description
We present results of study of oscillation of a sample of A-type mass-accreting components of Algol-type eclipsing binary stars (so called oEA stars). This work is a part of ongoing THAi Southern Survey for OEA Stars (THASSOS). High-precision photometry obtained at different observatories was used to investigate the low-amplitude acoustic variations of brightness of primary components. The new discovered oEA stars and detected acoustic oscillations are presented and discussed.
