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 review the application of the one-dimensional Mixing Length Theory (MLT) model of
convection in stellar interiors and low-mass stellar evolution. We summarize the history of …

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 present a study of 33 Kepler planet-candidate host stars for which asteroseismic
observations have sufficiently high signal-to-noise ratio to allow extraction of individual …

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 …

We present a new age-dating technique that combines gyrochronology with isochrone fitting
to infer ages for FGKM main-sequence and subgiant field stars. Gyrochronology 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 …

Kepler ultra-high precision photometry of long and continuous observations provides a
unique dataset in which surface rotation and variability can be studied for thousands of stars …

Among the available methods for dating stars, gyrochronology is a powerful one because it
requires knowledge of only the star's mass and rotation period. Gyrochronology relations …

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 …
