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 …

Context. Hierarchical triple stars are ideal laboratories for studying the interplay between
orbital dynamics and stellar evolution. Both mass loss from stellar winds and strong …

Context. The census of stellar and substellar companions of nearby stars is largely
incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is …

Abstract We describe the Milky Way Survey (MWS) that will be undertaken with the Dark
Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak …

Studies, have shown that the remnants of destroyed planets and debris-disk planetesimals
can survive the volatile evolution of their host stars into white dwarfs,, but few intact planetary …

We present an open-source Python package, Orbits from Radial Velocity, Absolute, and/or
Relative Astrometry (orvara), to fit Keplerian orbits to any combination of radial velocity …

The detonation of a sub-Chandrasekhar-mass white dwarf (WD) has emerged as one of the
most promising Type Ia supernova (SN Ia) progenitor scenarios. Recent studies have …

Context. The nearest stars provide a fundamental constraint for our understanding of stellar
physics and the Galaxy. The nearby sample serves as an anchor where all objects can be …

We construct from Gaia DR2 an extensive and very pure (contamination) catalogue of wide
binaries containing main-sequence (MS) and white dwarf (WD) components within 200 pc of …

Ultracompact binaries with orbital periods less than a few hours will dominate the
gravitational wave signal in the mHz regime. Until recently, 10 systems were expected to …
