Context. The census of stellar and substellar companions of nearby stars is largely incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is, however, fundamentally important in the understanding of the stellar and planetary formation and evolution mechanisms. Nearby stars are particularly favorable targets for high precision astrometry. Aims. We aim to characterize the presence of physical companions of stellar and substellar mass in orbit around nearby stars… 
High-speed stars: Galactic hitchhikers
Context. The search for stars born in the very early stages of the Milky Way star formation history is of paramount importance in the study of the early Universe since their chemistry carries
Detection of a Low-mass Stellar Companion to the Accelerating A2IV Star HR 1645
The $\sim500$\, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {\it Gaia}
Stellar clustering shapes the architecture of planetary systems
TLDR
Old, co-moving stellar groups around exoplanet host stars in the astrometric data from the Gaia satellite are identified and it is demonstrated that the architecture of planetary systems exhibits a strong dependence on local stellar clustering in position-velocity phase space.
Multiplicity of Galactic Cepheids and RR Lyrae stars from Gaia DR2
Context. Classical Cepheids (CCs) and RR Lyrae stars (RRLs) are important classes of variable stars used as standard candles to estimate galactic and extragalactic distances. Their multiplicity is
A surprise in the updated list of stellar perturbers of long-period comet motion
Context. The second Gaia data release (Gaia DR2) provided us with the precise five-parameter astrometry for 1.3 billion of sources. As stars passing close to the Solar System are thought to influence
Resolving the Multiplicity of Exoplanet Host Stars in Gemini/NIRI Data
The majority of stars have one or more stellar companions. As exoplanets continue to be discovered, it is crucial to examine planetary systems to identify their stellar companions. By observing a
Combining high-contrast imaging and radial velocities to constrain the planetary architectures of nearby stars
Context. Nearby stars are prime targets for exoplanet searches and characterization using a variety of detection techniques. Combining constraints from the complementary detection methods of
(Sub)stellar companions shape the winds of evolved stars
TLDR
The stellar winds of 14 stars during their asymptotic giant branch (AGB) phase of stellar evolution are observed and it is inferred that the same physics shapes both AGB winds and PNe; additionally, the morphology and AGB mass-loss rate are correlated.
Population-level Eccentricity Distributions of Imaged Exoplanets and Brown Dwarf Companions: Dynamical Evidence for Distinct Formation Channels
The orbital eccentricities of directly imaged exoplanets and brown dwarf companions provide clues about their formation and dynamical histories. We combine new high-contrast imaging observations of
Optimized modelling of Gaia–Hipparcos astrometry for the detection of the smallest cold Jupiter and confirmation of seven low-mass companions
To fully constrain the orbits of low-mass circumstellar companions, we conduct combined analyses of the radial velocity data and the Gaia and Hipparcos astrometric data for eight nearby systems.

TLDR
Analysis of 20 years of observations of Barnard’s star from seven facilities reveals a signal with a period of 233 days that is indicative of a companion planet, and a long-term modulation that could arise from a stellar magnetic-activity cycle or from a more distant planetary object is revealed.
