  • Survey of 108 E-S0 galaxies

    A survey has been performed of the morphological and photometric properties of 108 E-S0 galaxies out of a complete sample of 112: this sample is built from the Revised...
  • Photometry and Spectroscopy of Elliptical Galaxies

    Photometric and spectroscopic data are presented for a survey of the nearest and brightest elliptical galaxies. Distances, velocities relative to the cosmic rest frame, and...
  • Spectrophotometric Atlas of Standard Stellar Spectra

    Continuous spectrophotometry has been obtained for 200 objects at a resolution of 10-17 A over the wavelength region 360-1000nm. Kron-Cousins BVRI colors are computed for the...
  • UBV Photoelectric Sequences in SA 92-115

    The UBV system was originally defined by ten bright standard stars, primarily in the northern sky. These stars are too bright to be used with large telescopes and cannot be...
  • 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...
  • Galaxies Chemical and photometric evolution models

    We summarize the updated set of multiphase chemical evolution models performed with 44 theoretical radial mass initial distributions and 10 possible values of efficiencies to...
  • All-sky spectrally matched Tycho2 stars

    We present fitted UBVRI-ZY and u'g'r'i'z' magnitudes, spectral types, and distances for 2.4 million stars, derived from synthetic photometry of a library spectrum that best...
  • Optical Imaging of 57 spiral galaxies

    We present optical observations of a sample of 57 spiral galaxies and describe the procedures followed to reduce the data. We have obtained images in the optical B and I broad...
  • LAMOST DR5 catalogs

    We totally published 9,026,365 targets in this table, including 8,183,160 stars, 152,863 galaxies, 52,453 quasars, and 637,889 unknown objects. In addition, there are 5,808,985...
  • Millions of Optical Radio/X-ray Associations (MORX) v2

    The MORX (Millions of Optical - Radio/X-ray Associations) v2 catalog presents 3115575 optical objects which are calculated as being 40%-100% likely to be associated to radio or...
  • LAMOST DR7 catalogs

    The Data Release Seven of LAMOST Low-Resolution Spectroscopic Survey (LRS). The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a Chinese national...
  • GDR2AP. Gaia DR2, 2MASS, AllWISE astrophys. param.

    Stellar physical and dynamical properties are essential knowledge to understanding the structure, formation, and evolution of our Galaxy. We produced an all-sky uniformly...
  • LAMOST DR4 catalogs

    The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a Chinese national scientific research facility operated by the National Astronomical Observatories,...
  • LAMOST DR2 catalogs

    The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) general survey is a spectroscopic survey that will eventually cover approximately half of the celestial...
  • The MORX catalogue

    This automated catalogue combines all the largest published optical, radio and X-ray sky catalogues to find probable radio/X-ray associations to optical objects, plus double...
  • LAMOST DR1 catalogs

    The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) general survey is a spectroscopic survey that will eventually cover approximately half of the celestial...
  • Catalogue of field contact binary stars

    The catalogue of 361 galactic contact binaries is presented. Enlisted contact binaries are divided into five groups according to the type and quality of the available...
  • Light Curves of RS Pup

    Based on photographic plates from the Harvard College Observatory, we have made 1492 magnitude estimates for the long-period classical Cepheid RS Pup (P=41.4d). Together with...
  • Photoelectric observation of Cepheids

    From December 2006 to January 2008, we performed 1699 BVIc observations for 46 low-amplitude Cepheids discovered in the course of the ASAS project using the 76-cm telescope of...
  • V,pg light curves of NSV 9159

    We have obtained 530 photographic magnitude estimates for the long-period classical Cepheid NSV 9159 (P=39d) in the plate collections of the Harvard Observatory and the...
