The cores of main sequence intermediate-and high-mass stars are convective. Mixing at the
radiative–convective boundary, waves excited by the convection, and magnetic fields …

Massive stars play a major role not only in stellar evolution but also galactic evolution theory.
This is because of their dynamical interaction with binary companions, but also because …

Context. Main sequence stars with a convective core are predicted to stochastically excite
internal gravity waves (IGWs), which effectively transport angular momentum throughout the …

Massive stars die in catastrophic explosions that seed the interstellar medium with heavy
elements and produce neutron stars and black holes. Predictions of the explosion's …

Our ability to predict the structure and evolution of stars is in part limited by complex, 3D
hydrodynamic processes such as convective boundary mixing. Hydrodynamic simulations …

Context. Recent studies of massive stars using high-precision space photometry have
revealed that they commonly exhibit stochastic low-frequency (SLF) variability. This has …

The blue supergiant (BSG) problem, namely, the overabundance of BSGs inconsistent with
classical stellar evolution theory, remains an open question in stellar astrophysics. Several …

Main-sequence intermediate-mass stars present a radiative envelope that supports internal
gravity waves (IGWs). Excited at the boundary with the convective core, IGWs propagate …

Artificially increasing the luminosity and the thermal diffusivity of a model is a common tactic
adopted in hydrodynamical simulations of stellar convection. In this work, we analyse the …

Context. Eccentric ellipsoidal variables (also known as heartbeat stars) is a class of
eccentric binaries in which proximity effects, and tidal distortion due to time-dependent tidal …
