We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

Observational advances over the last decade have enabled high-resolution, interferometric
studies of forming multiple systems, statistical surveys of multiplicity in star-forming regions …

The mass–luminosity relation for late-type stars has long been a critical tool for estimating
stellar masses. However, there is growing need for both a higher-precision relation and a …

Abstract NASA's Kepler Space Telescope was designed to determine the frequency of Earth-
sized planets orbiting Sun-like stars, but these planets are on the very edge of the mission's …

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 …

The hierarchical triple-body approximation has useful applications to a variety of systems
from planetary and stellar scales to supermassive black holes. In this approximation, the …

Context. The astrometric discovery of sub-stellar mass companions orbiting stars is
exceedingly hard due to the required sub-milliarcsecond precision, limiting the application of …

The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

Precise and accurate parameters for late-type (late K and M) dwarf stars are important for
characterization of any orbiting planets, but such determinations have been hampered by …

The masses and radii of exoplanets are fundamental quantities needed for their
characterisation. Studying the different populations of exoplanets is important for …
