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 …

Binary stars are crucial laboratories for stellar physics, so have been photometric targets for
space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968 …

In this paper we present a catalog of 4584 eclipsing binaries observed during the first two
years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binary …

Our understanding of the properties and demographics of exoplanets critically relies on our
ability to determine the fundamental properties of their host stars. The advent of Gaia and …

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 …

We present a comparison of parallaxes and radii from asteroseismology and Gaia DR1
(TGAS) for 2200 Kepler stars spanning from the main sequence to the red-giant branch. We …

The Kepler mission has provided exquisite data to perform an ensemble asteroseismic
analysis on evolved stars. In this work we systematically characterize solar-like oscillations …

Investigations of the origin and evolution of the Milky Way disc have long relied on chemical
and kinematic identifications of its components to reconstruct our Galactic past. Difficulties in …

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

Abstract The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is a
dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a …
