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 …

Stars lose a significant amount of angular momentum between birth and death, implying that
efficient processes transporting it from the core to the surface are active. Space …

During most of their life, stars fuse hydrogen into helium in their cores. The mixing of
chemical elements in the radiative envelope of stars with a convective core is able to …

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. Eclipsing, spectroscopic double-lined binary star systems are excellent laboratories
for calibrating theories of stellar interior structure and evolution. Their precise and accurate …

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. Internal chemical mixing in intermediate-and high-mass stars represents an
immense uncertainty in stellar evolution models. In addition to extending the main sequence …

Aims. We investigated the thermal and chemical structure in the near-core region of stars
with a convective core by means of gravito-inertial modes. We determined the probing …

Context. The evolution of stars born with a convective core is highly dependent on the
efficiency and extent of near core mixing processes, which effectively increases both the …
