Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of...

Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small (R_p < 2 R_earth) ultra-short-period (USP)...

The Gaia mission is delivering a large number of astrometric orbits for binary stars. By combining these with spectroscopic orbits for systems with two observable spectra (SB2),...

The Gaia mission has provided us full astrometric solutions for over 1.5B sources. However, only the brightest 34M of those have radial velocity measurements. As a proof of...

WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of...

Deriving metallicities for solar-like stars follows well-established GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits....

The Transiting Exoplanet Survey Satellite (TESS) mission has provided the community with high-precision times series photometry for ~2.8 million stars across the entire sky via...

M-dwarf stars are the most common of potential exoplanet host stars in the Galaxy. It is therefore very important to understand planetary systems orbiting such stars and to...

VO-compliant publication of Schmidt survey SRC-J of the southern sky digitized with the MAMA microdensitometer at the Observatoire de Paris Image Analysis Centre (CAI).

VO-compliant publication of Schmidt survey ESO-R of the southern sky digitized with the MAMA microdensitometer at the Observatoire de Paris Image Analysis Centre (CAI).

SkyBoT is a VO service which allows to seek and identify solar system objects (planet, satellites, asteroids, comets) in any field of view at a given epoch (cone-search method)....

Keck-telescope spectrophotometry of the companion of PSR-J1810+1744 shows a flat, but asymmetric light-curve maximum and a deep, narrow minimum. The maximum indicates strong...

We present the first visual orbit for the nitrogen-rich Wolf-Rayet binary, WR133 (WN5o+O9I), based on observations made with the CHARA Array and the MIRC-X combiner. This orbit...

We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD307842 (TOI-784). The planet has a period of 2.8days, and the radial...

The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of...

We present a homogeneous compilation of HI spectral parameters extracted from global 21cm line spectra for some 9000 galaxies in the local universe (heliocentric velocity...

The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The...

This catalog lists coordinates, names, and radial velocities for 8250 galaxies scattered over the whole sky. Both optical and radio measures are included. The individual values...

The catalog contains a list of redshifts for Zwicky's Near Clusters. All of the 503 Zwicky Near Clusters as given in the Uppsala General Catalogue of Galaxies (UGC) are listed...

The catalog contains all bibliographical information pertaining to rotation curves of external galaxies that have appeared in the astronomical literature up to 1981 December....
