The primordial binary population II: Recovering the binary population for intermediate mass stars in Sco OB2

, 2007
We characterize the binary population in the young and nearby OB association Scorpius OB2 using available observations of visual, spectroscopic, and astrometric binaries with intermediate-mass primaries.

Unveiling Subarcsecond Multiplicity in the Pleiades with Gaia Multicolor Photometry

The Astronomical Journal
The list of 409 probable cluster members down to G = 15 ^mag ( m ≳ 0.5 M _⊙ ) is compiled for the two degree radius of the Pleiades, based on astrometric data from Gaia DR3 and the PPMXL catalog, along with several radial velocity surveys, including ...

A Catalog of Early-type Runaway Stars from LAMOST DR8

The Astrophysical Journal Supplement Series
Runaway stars are OB-type stars ejected from their birthplace with large peculiar velocities. The leading hypothesis addressed in their formation includes the supernova ejection mechanism and the dynamic ejection scenario.

Dynamical Masses for the Hyades Binary System vB 120

The Astrophysical Journal
We report spectroscopic observations of vB 120 (HD 30712), a 5.7 yr astrometric–spectroscopic binary system in the Hyades cluster. We combine our radial velocities with others from the literature, and with existing speckle interferometry measurements, to

The M4 Core Project with HST --- I. Overview and First-Epoch

, 2013
We present an overview of the ongoing Hubble Space Telescope large program GO-12911. The program is focused on the core of M4, the nearest Galactic globular cluster, and the observations are designed to constrain the number of binaries with massive ...

Astrometric Accelerations of Provisional Targets for the Habitable Worlds Observatory

The Astronomical Journal
NASA’s Habitable Worlds Observatory (HWO) will be the first space telescope capable of directly imaging Earth-like planets in the habitable zones (HZs) of Sun-like stars to probe their atmospheres for signs of life.
