Gaia Barium Dwarfs and Their Ostensibly Ordinary Counterparts

The Astrophysical Journal Letters
The recently identified Gaia population of main-sequence–white dwarf (MS+WD) binaries at separations of ∼1 au, often with moderate eccentricities, is not readily reproduced by binary population synthesis models.

Dynamical Architectures of S-type Transiting Planets in Binaries. I. Target Selection Using Hipparcos and Gaia Proper Motion Anomalies

The Astronomical Journal
The effect of stellar multiplicity on planetary architecture and orbital dynamics provides an important context for exoplanet demographics. We present a volume-limited catalog of up to 300 pc of 66 stars hosting planets and planet candidates from Kepler,
