Massive stars are important metal factories in the Universe. They have short and energetic
lives, and many of them inevitably explode as a supernova and become a neutron star or …

Context. The lack of high-precision long-term continuous photometric data for large samples
of stars has impeded the large-scale exploration of pulsational variability in the OB star …

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

Context. There is currently a niche for providing high-cadence, high resolution, time-series
optical spectroscopy from space, which can be filled by using a low-cost cubesat mission …

Abstract From 5.5 months of dual-band optical photometric monitoring at the 1 mmag level,
BRITE-Constellation has revealed two simultaneous types of variability in the O4I (n) fp star ζ …

Uncertainties in stellar structure and evolution theory are largest for stars undergoing core
convection on the main sequence. A powerful way to calibrate the free parameters used in …

Context. The BRIght Target Explorer (BRITE) mission is a pioneering space project aimed at
the long-term photometric monitoring of the brightest stars in the sky by means of a …

ABSTRACT ϵ Lupi A is a binary system consisting of two main-sequence early B-type stars
Aa and Ab in a short period, moderately eccentric orbit. The close binary pair is the only …

Context. Despite important advances in space asteroseismology during the last decade, the
early phases of evolution of stars with masses above~ 15 M⊙(including the O stars and their …

ABSTRACT O-stars are known to experience a wide range of variability mechanisms
originating at both their surface and their near-core regions. Characterization and …
