A Binary Origin for the First Isolated Stellar-mass Black Hole Detected with Astrometric Microlensing [PDF]
The Astrophysical Journal Letters, 2023 The Milky Way is believed to host hundreds of millions of quiescent stellar-mass black holes (BHs). In the last decade, some of these objects have been potentially uncovered via gravitational microlensing events.

Planetary systems in close binary stars: the case of HD 196885 [PDF]
Astronomy & Astrophysics, 2011 Context. More than fifty candidate planets are presently known to orbit one component of a binary or a multiple star system. Planets can therefore form and survive in such an environment, although recent observing surveys indicate that short-separation binaries do not favour the presence of a planetary system around one of the components.

The Astrophysical JournalClassical Wolf–Rayet (W-R) stars are the descendants of massive OB stars that have lost their hydrogen envelopes and are burning helium in their cores prior to exploding as Type Ib/c supernovae.

Prediction of Astrometric and Timing Microlensing Events with Pulsars by ATNF Catalog and Gaia DR3
The Astrophysical JournalDetermining the mass of neutron stars is crucial for understanding their formation, evolution, and interior structure. Currently, only a few dozen neutron stars have had their masses measured, and most of them belong to binary systems. However, there are

Spin–Orbit Alignment of Early-type Astrometric Binaries and the Origin of Slow Rotators [PDF]
The Astrophysical JournalThe spin–orbit alignment of binary stars traces their formation and accretion history. Previous studies of spin–orbit alignment have been limited to small samples, slowly rotating solar-type stars, and/or wide visual binaries that not surprisingly ...

Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse [PDF]
The Astrophysical JournalWe examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion that Betelgeuse might be a spectroscopic binary.

Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Diverse outcomes of binary-disk interactions [PDF]
Astronomy & Astrophysics, 2023 Circumstellar disks do not evolve in isolation, as about half of solar-type stars were born in binary or multiple systems. Resolving disks in binary systems provides the opportunity to examine the influence of stellar companions on the outcomes of planet

Binary parameters from astrometric and spectroscopic errors–candidate hierarchical triples and massive dark companions in Gaia DR3 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We show how astrometric and spectroscopic errors introduced by an unresolved binary system can be combined to give estimates of the binary period and mass ratio.
