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 …

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 …

Identifying terrestrial planets in the habitable zones (HZs) of other stars is one of the primary
goals of ongoing radial velocity (RV) and transit exoplanet surveys and proposed future …

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 …

ABSTRACT The primary Kepler Mission provided nearly continuous monitoring of∼
200,000 objects with unprecedented photometric precision. We present the final catalog of …

Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

The determination of exoplanet properties and occurrence rates using Kepler data critically
depends on our knowledge of the fundamental properties (such as temperature, radius, and …

Gaseous disks have been proposed as a mechanism for facilitating mergers of binary black
holes. We explore circumbinary disk systems to determine the evolution of the central binary …

Abstract The Kepler Mission is a space observatory launched in 2009 by NASA to monitor
170 000 stars over a period of four years to determine the frequency of Earth-size and larger …

The search for habitable planets has revealed many planets that can vary greatly from an
Earth analog environment. These include highly eccentric orbits, giant planets, different bulk …
