Yearslong time series of high-precision brightness measurements have been assembled for
thousands of stars with telescopes operating in space. Such data have allowed astronomers …

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 …

In this paper we present a catalog of 4584 eclipsing binaries observed during the first two
years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary …

Context. The Gaia mission has delivered hundreds of thousands of variable star light curves
in multiple wavelengths. Recent work demonstrates that these light curves can be used to …

Context. Massive stars are predicted to excite internal gravity waves (IGWs) by turbulent core
convection and from turbulent pressure fluctuations in their near-surface layers. These IGWs …

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. The third Gaia data release provides photometric time series covering 34 months
for about 10 million stars. For many of those stars, a characterisation in Fourier space and …

Context. The empirical distribution of projected rotational velocities (v sin i) in massive O-
type stars is characterised by a dominant slow velocity component and a tail of fast rotators …

The mass of a star is the most fundamental parameter for its structure, evolution, and final
fate. It is particularly important for any kind of stellar archaeology and characterization of …

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