Astrometric binaries and their role in double star astronomy

Astrophysics and Space Science, 1985
Discussing the relationship between the astrometric binaries and the family of double stars is somewhat like dealing with the ‘philosophy’ of this type of binaries. Available evidence points toward the assumption that we encounter here primarily a specific technique of observation rather than a specific type of objects.

Millions of main-sequence binary stars from Gaia BP/RP spectra

Astronomy & Astrophysics
We present an extensive catalog of likely main-sequence main-sequence (MSMS) binary stars systems derived from Gaia Data Release 3 BP/RP (XP) spectra through the comparison of single- and binary-star model fits.

Distributions of Wide Binary Stars in Theory and in Gaia Data. III. Orbital Momenta, Masses, and Manifestations of MOND

Astronomical Journal
Using the censored catalog of 103,169 resolved Gaia DR3 binary stars with accurate astrometric data for each component, a new observable, object-specific parameter is computed for each pair: the projected orbital momentum.

Identifying Binary Stars in the HARPS Database with Gaia Astrometry, Photometry, and Radial Velocities

Research Notes of the AAS
I identify binaries among stars monitored by the High-Accuracy Radial velocity Planetary Searcher spectrograph using radial velocities (RVs), Gaia astrometry, and photometry. Out of 141 Gaia-selected targets, I identify 68 photometric binaries and report

Tales of stellar and binary coevolution, told by stellar oscillations. Binary demographics and their impact on stellar mass, orbits, and age estimates in main-sequence and red-giant stars

Astronomy & Astrophysics
Red giants are increasingly used as stellar population tracers due to their well-understood evolution and the availability of asteroseismic observables. However, stellar binarity can alter observable properties and introduce strong biases.

Comprehensive Gaia DR3-Based Astrometric, Photometric, and Kinematic Studies of the Binary Open Cluster $h$ and $\chi$ Persei

Research in Astronomy and Astrophysics
In the {\it Gaia} era, a comprehensive analysis of the binary open clusters NGC\, 869 ($h$ Persei) and NGC\,884 ($\chi$ Persei) system has been conducted to investigate its structural, astrophysical, kinematic, and Galactic orbital properties, along ...

Precision astrometry mission for exoplanet detection around binary stars

Astronomical Telescopes + Instrumentation, 2018
We propose an innovative low-cost mission capable of detecting potentially habitable planets around a sample of solartype stars near the sun. The finding of rocky planets in temperate orbits among our immediate stellar neighbors will be a signature ...
