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 …

We are entering a golden era for stellar physics driven by satellite and telescope
observations of unprecedented quality and scope. New insights on stellar evolution and …

The ensemble of chemical element abundance measurements for stars, along with precision
distances and orbit properties, provides high-dimensional data to study the evolution of the …

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

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 …

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 …

ABSTRACT The Kepler Mission, launched on 2009 March 6, was designed with the explicit
capability to detect Earth-size planets in the habitable zone of solar-like stars using the …

Red giants are evolved stars that have exhausted the supply of hydrogen in their cores and
instead burn hydrogen in a surrounding shell,. Once a red giant is sufficiently evolved, the …

Context. The space mission Kepler provides us with long and uninterrupted photometric time
series of red giants. We are now able to probe the rotational behaviour in their deep interiors …

When the core hydrogen is exhausted during stellar evolution, the central region of a star
contracts and the outer envelope expands and cools, giving rise to a red giant. Convection …
