  • LSB galaxies rotation curves

    File rawcurve contains the raw rotation curves of the low surface brightness galaxies. These data are not corrected for inclination. File procurve contains the processed...
  • Cepheids in Magellanic Clouds. II.

    The analysis of CCD observations of ten new suspected second overtone mode Cepheids in the SMC does not confirm the nature of such stars; most of them appear to be first...
  • HST VI photometry and proper motions in NGC 6528

    Using two epochs of HST/WFPC2 images of the metal-rich globular cluster NGC 6528 we derive the proper motions of the stars and use them to separate the stars belonging to NGC...
  • Long-Term Polarization of BL Lac

    Both photometric and polarimetric data of BL Lac were obtained with the .5-m telescopes of the Byurakan station of the Astronomical Institute of St.-Petersburg University.
  • Search for duplicity in periodic Be stars

    Four Be stars, HR 1960, HR 2968, HR 3237 and HR 3642, selected according to their periodic variations in Hipparcos and Geneva photometries, have been monitored from 1998 until...
  • UBVI photometry of NGC 7036 and NGC 7772

    We present CCD UBVI observations obtained in the field of the two previously unstudied dissolving open cluster candidates NGC 7036 and NGC 7772. Our analysis suggests that both...
  • 319 gamma-ray bursts BATSE triggers

    A comprehensive temporal analysis has been performed on the 319 brightest GRBs with T_90_>2s from the BATSE (Cat. ) current catalog. The GRBs were denoised using wavelets and...
  • JacobsUni EPN TAP service

    The JacobsUni EPN's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It...
  • JacobsUni EPN Dataset Delivery

    This service delivers (most of) the datasets held at JacobsUni EPN. In addition to the default (nonstandard) way of just appending accrefs to the get access URL, there is also a...
  • JacobsUni EPN Registry

    The publishing registry for the JacobsUni EPN.
  • uvby{beta} photometry of early type stars

    The {beta} Cephei stars and slowly pulsating B (SPB) stars are massive main sequence variables. The strength of their pulsational driving strongly depends on the opacity of...
  • SwiftFT catalog

    An accurate census of the active galactic nuclei (AGN) is a key step in investigating the nature of the correlation between the growth and evolution of super massive black holes...
  • Normalized spectra of 20 red giants

    Accurate fundamental parameters of stars are mandatory for the asteroseismic investigation of the Kepler mission to succeed. We determine the atmospheric parameters for a sample...
  • QSOs CaII absorbers

    We present a systematic study of weak intervening CaII absorbers at low redshift (z<0.5), based on the analysis of archival high-resolution (R>=45000) optical spectra of...
  • Heliospheric density and magnetic field model

    The radial evolution of the density of the plasma and the magnetic field in the heliosphere, especially in the region between the solar corona and the Earth's orbit, has been a...
  • Synthetic lines in the Sun

    We have computed synthetic spectra from a realistic 3D numerical simulation of the solar photosphere. We provide the spatially averaged spectra for selected lines that are...
  • Radial velocities of HD 10180

    Low-mass extrasolar planets are presently being discovered at an increased pace by radial velocity and transit surveys, which opens a new window on planetary systems. We are...
  • GJ3634 radial velocity and 4.5um flux

    We report on the detection of GJ3634b, a super-Earth of mass msini=7.0+/-0.9 Mearth and period P=2.64561+/-0.00066-day. Its host star is a M2.5 dwarf, has a mass of...
  • GALEX Ultraviolet Virgo Cluster Survey (GUViCS)

    The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering ~40 sq. deg in the far UV (FUV, {lambda}eff=1539{AA},...
  • Archive of the FAI AZT-8

    The archive of digitized plates obtained on AZT-8 at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. They represent the results of photometric observations of...
