Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with
either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing …

Context. The multiplicity fraction of stars, down to the substellar regime, is a parameter of
fundamental importance for stellar formation, evolution, and planetology. The census of …

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 …

We present the results of a comprehensive assessment of companions to solar-type stars. A
sample of 454 stars, including the Sun, was selected from the Hipparcos catalog with π> 40 …

We present results of the largest, most comprehensive study ever done of the stellar
multiplicity of the most common stars in the Galaxy, the red dwarfs. We have conducted an …

Data on the multiplicity of F-and G-type dwarf stars within 67 pc of the Sun are presented.
This distance-limited sample based on the Hipparcos catalog contains 4847 primary stars …

We present results from a high-contrast adaptive optics imaging search for giant planets and
brown dwarfs (≳ 1 M Jup) around 122 newly identified nearby (≲ 40 pc) young M dwarfs …

We present the discovery from Transiting Exoplanet Survey Satellite (TESS) data of LTT
1445Ab. At a distance of 6.9 pc, it is the second nearest transiting exoplanet system found to …

Aims. Our goal is to study the different morphologies associated to the interaction of the
stellar winds of AGB stars and red supergiants with the interstellar medium (ISM) to follow …

Context. The multiplicity of classical Cepheids (CCs) and RR Lyrae stars (RRLs) is still
imperfectly known, particularly for RRLs. Aims. In order to complement the close-in short …
