文献摘要
We report the discovery of two massive eccentric systems with BRITE data, Ori and Lib, showing heartbeat effects close to the periastron passage. Lib exhibits shallow eclipses that will soon vanish due to the apsidal motion in the system. In neither system, tidally excited oscillations were detected.
