Stellar multiplicity is a ubiquitous outcome of the star-formation process. The frequency and
main characteristics of multiple systems, and their dependence on primary mass and …

Binary stars are as common as single stars. Binary stars are of immense importance to
astrophysicists because that they allow us to determine the masses of the stars independent …

We compile observations of early-type binaries identified via spectroscopy, eclipses, long-
baseline interferometry, adaptive optics, common proper motion, etc. Each observational …

Searching for distinctive signatures, which characterize different formation channels of
binary black holes (BBHs), is a crucial step towards the interpretation of current and future …

We report the statistical properties of stars, brown dwarfs and multiple systems obtained from
the largest radiation hydrodynamical simulation of star cluster formation to date that resolves …

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 …

Eccentricity of wide binaries is difficult to measure due to their long orbital periods. With
Gaia's high-precision astrometric measurements, eccentricity of a wide binary can be …

Context. As endpoints of stellar evolution, white dwarfs (WDs) are powerful tools to study the
evolutionary history of the Galaxy. In particular, the multiplicity of WDs contains information …

We use a homogeneous catalogue of 42 000 main-sequence wide binaries identified by
Gaia to measure the mass ratio distribution, p (q), of binaries with primary masses 0.1< M …

Millimeter-sized dust grains experience radial velocities exceeding the gas velocities by
orders of magnitude. The viscous evolution of the accretion disk adds disk material onto the …
