τ Ori and τ Lib: Two New Massive Heartbeat Binaries
Abstract
We report the discovery of two massive eccentric systems with BRITE data, τ Ori and τ Lib, showing heartbeat effects close to the periastron passage. τ Lib exhibits shallow eclipses that will soon vanish due to the apsidal motion in the system. In neither system, tidally excited oscillations were detected.
