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 …

Until the last few decades, investigations of stellar interiors had been restricted to theoretical
studies only constrained by observations of their global properties and external …

A knowledge of stellar ages is crucial for our understanding of many astrophysical
phenomena, and yet ages can be difficult to determine. As they become older, stars lose …

We use asteroseismic data from the Kepler satellite to determine fundamental stellar
properties of the 66 main-sequence targets observed for at least one full year by the mission …

Ensemble studies of red-giant stars with exquisite asteroseismic (Kepler), spectroscopic
(APOGEE), and astrometric (Gaia) constraints offer a novel opportunity to recast and …

The advent of space-based missions like Kepler has revolutionized the study of solar-type
stars, particularly through the measurement and modeling of their resonant modes of …

We present the first APOKASC catalog of spectroscopic and asteroseismic data for dwarfs
and subgiants. Asteroseismic data for our sample of 415 objects have been obtained by the …

Studies using asteroseismic ages and rotation rates from star-spot rotation have indicated
that standard age–rotation relations may break down roughly half way through the main …

Constraints on the formation and evolution of the Milky Way Galaxy require multidimensional
measurements of kinematics, abundances, and ages for a large population of stars. Ages for …

We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source
code written in Python to determine stellar properties based on a set of astrophysical …
