  • Galactic post-AGB stars multi-phot.

    When low- and intermediate-mass stars leave the asymptotic giant branch (AGB) phase, and before they reach the planetary nebula stage, they enter a very brief and rather...
  • The new Herschel/PACS Point Source Catalogue

    Herschel operated as an observatory, therefore it did not cover the whole sky, but still observed ~8% of it. The first version of an overall Herschel/PACS Point Source Catalogue...
  • Faraday tomography of LoTSS-DR2 - inner Galaxy

    The LOw-Frequency ARray (LOFAR) provides a unique opportunity to probe the magneto-ionised structure of our Galactic neighbourhood with great resolution. In this work, we...
  • Updated BOSZ synthetic stellar spectral library

    The modeling of stellar spectra of flux standards observed by the Hubble and James Webb space telescopes requires a large synthetic spectral library that covers a wide...
  • GJ 1289 and GJ 3378 RV, B and DetlaT

    We report the discovery of two new exoplanet systems around fully convective stars, found from the radial-velocity (RV) variations of their host stars measured with the nIR...
  • Ariel homogeneous stellar C, N, O abundances

    One of the ultimate goals of the ESA Ariel space mission is to shed light on the formation pathways and evolution of planetary systems in the Solar neighbourhood. Such an...
  • MCXC Second release (MCXC-II)

    We present the second release of the Meta-Catalogue of X-ray detected Clusters of galaxies (hereafter MCXC-II). The MCXC-II has been compiled from publicly available ROSAT All...
  • Radial gradient of stellar populations

    In this paper we present the analysis of Hubble Space Telescope (HST) observations of the globular cluster Omega Centauri. Our analysis combines data obtained in this work with...
  • SPIRou spectra of 14 transiting exoplanets

    For several years, the metastable helium triplet line has been successfully used as a tracer to probe atmospheric escape in transiting exoplanets. This absorption in the...
  • SSHADE bandlist library

    SSHADE bandlist library.
  • SSHADE spectra library

    SSHADE spectra library.
  • CfA Redshift Catalog (June 1995 Version)

    The ZCAT database contains the CfA Redshift Catalog, which incorporates much of the latest velocity data from the Whipple Observatory and other sources, as well as velocities...
  • XMM-Newton Wide Angle Survey

    This table contains results from the XMM-Newton Wide Angle Survey (XWAS), viz., a new catalog of almost a thousand X-ray sources that have been spectroscopically identified...
  • XTE Archived Public Slew Data

    This database table is a catalog of all the RXTE slew observations and is based on information culled from the RXTE Data Archive's latest top-level FMI (FITS Master Index)...
  • XTE All-Sky Slew Survey Catalog

    The Rossi X-Ray Timing Explorer (RXTE) All-Sky Survey Slew Catalog contains the results of a serendipitous hard X-ray (3 - 20 keV), nearly all-sky (|b|>10 degrees) survey...
  • SkyView Virtual Observatory

    SkyView is a Virtual Observatory on the Net. Astronomers can generate images of any portion of the sky at wavelengths in all regimes from radio to gamma-ray. Users tell SkyView...
  • XMM-Newton Medium Sensitivity Survey (XMS) Source Catalog

    X-ray sources at intermediate fluxes (a few x 10<sup>-14</sup> erg/cm<sup>2</sup>/s) with a sky density of ~ 100 deg<sup>2</sup> are...
  • XMM-Newton XAssist Source List

    This database table contains the latest XMM-Newton XAssist source list. XAssist is a NASA-funded project for the automation of X-ray astrophysics, with emphasis on galaxies. It...
  • Ensemble X-Ray Variability of AGN in 2XMMi-DR3

    The X-ray variability of active galactic nuclei (AGN) has been most often investigated with studies of individual, nearby sources, and only a few ensemble analyses have been...
  • 2XMM Flares Detected from Tycho-2 Stars

    This table contains the results from a uniform, large-scale survey of X-ray flare emission, based on the XMM-Newton Serendipitous Source Catalog (2XMM) and its associated data...
