The Local Void is one of the nearest large voids, located at a distance of 23Mpc. It lies largely behind the Galactic Bulge and is therefore extremely difficult to observe. We...

The improved astrometry precision of Gaia-eDR3 allows us to perform a detailed study of the Upper Scorpius OB association and revisit its spatial, kinematic, and age...

Gaia Data Release 3 (DR3) provides >181000 radial velocity (RV) solutions for single-lined spectroscopic binaries (SB1s) that can be used to search for non-interacting...

We present the confirmation of HD 190360 d, a warm (P=88.690_-0.049_^+0.051^days), low-mass (m.sin(i)=10.23_-0.80_^+0.81^M_{Earth}) planet orbiting the nearby (d=16.0pc),...

The NEID Earth Twin Survey (NETS) has been delivering a rich set of precise radial velocity (RV) measurements for 41 bright, nearby main-sequence stars. Here, we describe the...

We present a kinematic study of young stars in Messier 16 (M16) using the Gaia Data Release 3 and high-resolution spectra. A total of 345 stars are selected as genuine members...

The shape and kinematics of the metal-poor stellar component of the Galactic bulge remain poorly characterized, so its origin is still weakly constrained. RR Lyrae (RRL) stars...

We present the analysis of five long-period TESS Objects of Interest (TOIs), each with orbital periods exceeding one month. Initially identified by the Transiting Exoplanet...

We present statistical results from the Epoch of Giant Planet Migration RV planet search program. This survey was designed to measure the occurrence rate of giant planets...

The Survey for Distant Solar Twins aims to find stars very similar to the Sun at distances of 1-4kpc, several times more distant than any currently known solar twins and...

We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of 1.081+/-0.047 RJ and a mass of 4.78^+0.39^_-0.37_MJ on a long period...

We present the kinematic analysis of 246 stars within 4' from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the...

Anomalous Cepheids are radially pulsating stars observed in dwarf galaxies, the Galactic bulge and halo, and globular clusters. Similarly to other radially pulsating stars, they...

Understanding the natal kicks received by neutron stars (NSs) during formation is a critical component of modelling the evolution of massive binaries. Natal kicks are an...

NGC 2509 is a distant (~2.5kpc) and little-studied open cluster located in the third Galactic quadrant. It is a moderately old cluster, whose age has not yet been precisely...

We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multiwavelength and multimessenger...

Hot subdwarf binaries provide stringent constraints on envelope stripping and binary mass transfer. However, robust identification of these systems in large spectroscopic...

We present the first planet mass measurement obtained with CRIRES+ radial velocity (RV) observations using the K-band gas cell. Our target, LHS 3844 b (TOI-136), is a transiting...

Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability. We present a...

OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution,...
