  • Data Central SCS

    Data Central Simple Cone Search. Access Data Central and other catalogues.
  • Data Central SSA

    Spectra from surveys hosted by Data Central. Most spectra were taken with the multi-object spectroscopy facilities 2dF (Anglo-Australian Telescope) and 6dF (UK Schmidt Telescope).
  • Radial Velocities for High Proper Motion Stars

    The machine-readable version of Radial Velocities of High Proper Motion Stars contains UBV photometry, proper motions, and radial (line-of-sight) velocities for 878...
  • Double stars with wide separations in the AGK3

    A large list of common proper motion stars selected from the third Astronomischen Gesellschaft Katalog (AGK3) was monitored with the CORAVEL (for COrrelation RAdial VELocities)...
  • Model Atmospheres

    (no description available)
  • Grids of ATLAS9 Model Atmospheres and MOOG spectra

    A grid of ATLAS9 model atmospheres has been computed, spanning Teff in 3500--8000K, log.g in 0.0--5.0, [Fe/H] in -4.0--0.0, [{alpha}/Fe] in -0.08--1.2. These parameters are...
  • Horizontal Branch Stellar Model Calculations

    This data set consists of evolutionary sequences from the Zero Age Horizontal Branch (ZAHB) to the point where log L/Lsun reaches 2.25 on the lower AGB. These calculations have...
  • Finding List of Interacting Binaries, 5th ed.

    This catalog is abstracted from the Card Catalog maintained at the University of Florida containing information on all published, and to the extent available, unpublished work...
  • Limb-darkening for Space Mission GAIA

    In the past few years, the number of space missions with astrophysical purposes has increased, with COROT, KEPLER, MOST and more recently TESS. Two of the most important...
  • Bright white dwarfs for high-speed photometry

    The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will obtain space-based uninterrupted light curves for a large sample of bright white dwarfs distributed across...
  • Wide binaries in Tycho-Gaia: search method

    We mine the Tycho-Gaia astrometric solution (TGAS) catalogue for wide stellar binaries by matching positions, proper motions and astrometric parallaxes. We separate genuine...
  • Stellar twins in RAVE with Gaia

    We apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large data set,...
  • YJKs light curves of SMC Classical Cepheids

    The VISTA near-infrared YJKs survey of the Magellanic System (VMC) is collecting deep Ks-band time-series photometry of pulsating stars hosted by the two Magellanic Clouds and...
  • Kinematic data for stars in OB-associations

    We use stellar proper motions from the catalog TGAS (2016, Cat. I/337) to study the kinematics of OB-associations identified by Blaha and Humphreys (1989AJ.....98.1598B). The...
  • Radial velocities of 1453 FGK

    We present the second paper of a series of publications aiming at obtaining a better understanding regarding the nature of type Ia supernovae (SN Ia) progenitors by studying a...
  • Detecting damped Ly{alpha} absorbers

    We develop an automated technique for detecting damped Ly{alpha} absorbers (DLAs) along spectroscopic lines of sight to quasi-stellar objects (QSOs or quasars). The detection of...
  • Hierarchical formation of Westerlund 1

    We examine the level of substructure and mass segregation in the massive, young cluster Westerlund 1. We find that it is relatively smooth, with little or no mass segregation,...
  • KX redshift survey

    In this paper we present preliminary spectroscopic results from a small-area faint K-excess (KX) survey, and compare KX selection against UVX selection. The aim of the KX method...
  • The 2dF QSO Redshift Survey. VIII

    We examine the highest signal-to-noise ratio spectra from the 2dF QSO Redshift Survey (2QZ) 10k release (Cat. ) and identify over 100 new low-ionization heavy-element absorbers:...
