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 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 …

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 …

Many close stellar binaries are accompanied by a faraway star. The" eccentric Kozai-
Lidov"(EKL) mechanism can cause dramatic inclination and eccentricity fluctuations …

We report the first discovery of a transiting circumbinary planet detected from a single sector
of Transiting Exoplanet Survey Satellite (TESS) data. During Sector 21, the planet TIC …

All four circumbinary (CB) protoplanetary disks orbiting short-period (P< 20 days) double-
lined spectroscopic binaries (SB2s)—a group that includes UZ Tau E, for which we present …

We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest
addition to the still-small family of CBPs defies the current trend of known short-period …

Abstract The TMT Detailed Science Case describes the transformational science that the
Thirty Meter Telescope will enable. Planned to begin science operations in 2024, TMT will …

The habitable zone (HZ) is the circular region around a star (s) where standing bodies of
water could exist on the surface of a rocky planet. Space missions employ the HZ to select …
