We present a comprehensive study of mid-infrared neutral hydrogen (HI) emission lines in 79 nearby (d<200pc) young stars using the James Webb Space Telescope (JWST)...

Classical Cepheids (CCs) have long been considered excellent tracers of the chemical evolution of the Milky Way's young disk. We present a homogeneous, Non-Local Thermodynamical...

In this study, we develop a membership identification method and apply it for 30 open clusters (OCs) within 200pc of the Sun using astrometric data of Gaia DR3. By accounting...

We have compiled a list of blue lurker (BL) candidates in open clusters using the available rotation catalogs. Blue lurkers are rejuvenated main-sequence stars hidden among...

This schema contains data re-published from the official Gaia DR3 TAP services (e.g., ivo://uni-heidelberg.de/gaia/tap). It provides simplified access to data related to...

The present high accuracy of stellar positions and proper motions allows us to determine the positional accuracy of old stellar catalogues. This has already been done for the...

We report discoveries of 165 new quasar Ca II absorbers from the Sloan Digital Sky Survey (SDSS) Data Releases 7 and 12. Our CA II rest-frame equivalent width distribution...

We present the results from studying 140 radio sources in the GLEAM (GaLactic and Extragalactic All-sky MWA [Murchison Widefield Array]) 4-Jy (G4Jy) Sample. These sources were...

Three-body interactions can eject stars from the core of a globular cluster, causing them to enter the Galactic halo as extra-tidal stars. While finding extra-tidal stars is...

Radial colour gradients within galaxies arise from gradients of stellar age, metallicity, and dust reddening. Large samples of colour gradients from wide- area imaging surveys...

We analyse the spatial statistics of the 2D gas-phase oxygen abundance distributions in a sample of 219 local galaxies. We introduce a new adaptive binning technique to enhance...

We present the Living Swift-XRT Point Source (LSXPS) catalogue and real-time transient detector. This system allows us for the first time to carry out low- latency searches for...

We present a search for z ~= 7 Lyman-break galaxies using the 1.72 deg^2^ near-infrared UltraVISTA survey in the COSMOS field, reaching 5 {sigma} depths in Y of 26.2. We...

The UCAC3 all-sky CCD astrograph catalogue, minus the fields from 2MASS and SuperCosmos and matching/object flags (which can be recovered with a local crossmatch).

ARI's "Geschichte des Fixsternhimmels" is an attempt to collect all astrometrically useful observations from before ca. 1970 in a way comparable to what has been done to...

HSOY is a catalog of 583'001'653 objects with precise astrometry based on PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are below 1 mas/yr for...

The LSPM catalog is a comprehensive list of 61,977 stars north of the J2000 celestial equator that have proper motions larger than 0.15"/yr (local-background-stars frame)....

The main result catalog from the ESA Hipparcos satellite, obtained November 1989 through March 1993. In the GAVO DC, several columns were left out and all angles are given in...

The SuperCOSMOS data primarily originate from scans of the UK Schmidt and Palomar POSS II blue, red and near-IR sky surveys. The ESO Schmidt R (dec < -17.5) and Palomar...

This is a “light” version of the full Gaia DR2 gaia_source table, containing the original astrometric and photmetric columns with just enough additional information to let...
