Low-frequency Variability in Massive Stars: Core Generation or Surface Phenomenon?
Low-frequency Variability in Massive Stars: Core Generation or Surface Phenomenon?
Bowman et al. (2019) reported low-frequency photometric variability in 164 O- and B-type stars observed with K2 and TESS. They interpret these motions as internal gravity waves, which could be excited stochastically by convection in the cores of these stars. The detection of internal gravity waves in massive stars would …
