We predict the flux and surface velocity perturbations produced by convectively excited gravity modes (g-modes) in main-sequence stars. Core convection in massive stars can excite g-modes to sufficient amplitudes to be detectable with high-precision photometry by Kepler and Convection, Rotation and planetary Transits (CoRoT), if the thickness of the convective overshoot region is 30percent of a pressure scale height. The g-modes manifest as excess photometric variability, with amplitudes of ∼10… Expand

Photometric detection of internal gravity waves in upper main-sequence stars: I. Methodology and application to CoRoT targets
Context. Main sequence stars with a convective core are predicted to stochastically excite Internal Gravity Waves (IGWs), which effectively transport angular momentum throughout the stellar interiorExpand
Asteroseismic signatures of the helium core flash

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 beExpand

Angular Momentum Transport via Internal Gravity Waves in Evolving Stars
Recent asteroseismic advances have allowed for direct measurements of the internal rotation rates of many sub-giant and red giant stars. Unlike the nearly rigidly rotating Sun, these evolved starsExpand
