V453 Cyg is an eclipsing binary containing 14 Msun and 11 Msun stars in an eccentric short-period orbit. We have discovered $\beta$ Cep-type pulsations in this system using TESS data. We identify seven significant pulsation frequencies, between 2.37

The analysis of eclipsing binaries with massive components enables to test stellar evolution models and track selected aspects of the structure of early-type stars. Stellar pairs with B-type components may serve to find tighter constraints on the mec
