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 …

The Sun and other stars are magnetic: magnetism pervades their interiors and affects their
evolution in a variety of ways. In the Sun, both the fields themselves and their influence on …

We substantially update the capabilities of the open-source software instrument Modules for
Experiments in Stellar Astrophysics (MESA). MESA can now simultaneously evolve an …

The age of gravitational-wave astronomy has begun, and black hole (BH) mergers detected
by the Laser Interferometer Gravitational-Wave Observatory (LIGO) are providing novel …

The angular momentum (AM) evolution of stellar interiors, along with the resulting rotation
rates of stellar remnants, remains poorly understood. Asteroseismic measurements of red …

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing
accurate key planet parameters (radius, mass, density and age) in statistical numbers, it …

We present a catalog of stellar properties for a large sample of 6676 evolved stars with
Apache Point Observatory Galactic Evolution Experiment spectroscopic parameters and …

Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

The determination of exoplanet properties and occurrence rates using Kepler data critically
depends on our knowledge of the fundamental properties (such as temperature, radius, and …

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 …
