Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

The astrophysical origin of gravitational wave (GW) events discovered by LIGO/VIRGO
remains an outstanding puzzle. In active galactic nuclei (AGNs), compact-object binaries …

Hot Jupiters were the first exoplanets to be discovered around main sequence stars and
astonished us with their close-in orbits. They are a prime example of how exoplanets have …

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

Thousands of exoplanets have now been discovered with a huge range of masses, sizes
and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host …

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 …

Abstract The Transiting Exoplanet Survey Satellite (TESS) is finding transiting planet
candidates around bright, nearby stars across the entire sky. The large field of view …

We provide a brief review of many aspects of the planetary physics of hot Jupiters. Our aim is
to cover most of the major areas of current study while providing the reader with additional …

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 …
