The transition regime between giant planets (GPs) and brown dwarfs (BDs) is still an open subject of study in exoplanetary science. A complete understanding of the population of...

The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. We aim to understand the...

Observations of companions of solar-type stars in nearby young moving groups (NYMGs) show that they split into two groups: stellar and brown dwarf companions (mass ratio...

The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...

The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...

Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since...

We present a detailed chemical abundance analysis of the brightest star in the ultrafaint dwarf (UFD) galaxy candidate Cetus II from high-resolution Magellan/MIKE spectra. For...

We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (M: 0.99M_{sun}_; R: 1.13R_{sun}; age: 7.4Gyr; Vmag: 8.25)...

Dwarf galaxies like Sagittarius (Sgr) provide a unique window into the early stages of galactic chemical evolution, particularly through their metal-poor stars. By studying the...

NGC 2506 is a rich, intermediate-age (2.0Gyr), metal-poor ([Fe/H]~-0.2) open cluster. This work presents the results of 12,157 spectroscopic radial-velocity measurements of 2442...

We have determined masses, stellar mass functions, and structural parameters of 112 Milky Way globular clusters by fitting a large set of N-body simulations to their velocity...

The catalog results from a survey for distant Field K giants in the Galactic halo made for purposes of locating a chemically and kinematically unbiased sample out to about 25...

This catalogue includes the DDO photometry and the radial velocities observed for the study of the kinematics and abundance gradients of G and K stars in the Galactic poles...

This document describes the magnetic tape version of a catalog of 1440 O-B5 star with radial velocities accurate to within 5 km/sec, located within 3 kpc of the sun and within...

With Gaia Data Release 3 (DR3), new and improved astrometric, photometric, and spectroscopic measurements for 1.8 billion stars have become available. Alongside this wealth of...

This SAO catalogue (Smithsonian Astrophysical Observatory Catalogue of 258,997 stars, 1966; see catalog ), connected to the CSI (Catalogue of Stellar Identifications, see...

The dataset lists all the confirmed globular clusters (GC), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were...

The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources....

This catalogue is a compilation of the original data related to stars in the Large Magellanic Cloud (LMC); it concerns essentially the stars brighter than m_pg_=13.5. The list...

Ages, chemical compositions, velocity vectors, and Galactic orbits for stars in the solar neighbourhood are fundamental test data for models of Galactic evolution. The...
