000007348 520__ $$aMassive stars are the most important building blocks of our universe. When they explode as supernovae, they enrich their environments with the elements from which the next generation of stars are formed. Amongst the OB stars, different types of stellar pulsations are observed that can be used to study the interiors of massive stars with asteroseismic tools. There are several excitation mechanisms at play and different factors like opacities, the interior mixing, rotation, and temperature profile, tidal forces, magnetic fields, mass loss, and stellar winds influence their pulsations. Thanks to the arrival of space missions providing ultra-precise light curves with a sufficiently long time base, including the BRITE constellation, we now have observations revealing signatures that can be used to study their effect. In this talk, I will focus on some of them to highlight the importance of the arrival of the space era to improve our understanding of OB stars.
