  • AB-type RR Lyrae stars from ASAS and WASP

    In this article, we present results based on high-density, high-precision Wide-Angle Search for Planets (WASP) light curves supplemented with lower-precision photometry from the...
  • Edge-on HI-rich LSB galaxies from ALFALFA

    Low surface brightness galaxies (LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies...
  • X-shaped radio galaxies from FIRST

    We present a catalog of 290 "winged" or X-shaped radio galaxies (XRGs) extracted from the latest (2014 December 17) data release of the "Very Large Array Faint Images of the...
  • Linear structural param. of SDSS+UKIDSS+WISE gal.

    Accurate measurements of galaxy structure are prerequisites for quantitative investigation of galaxy properties or evolution. Yet galaxy inclination, through projection and...
  • New HIP-based parallaxes for 424 faint stars

    We present a catalog of 424 common proper-motion companions to Hipparcos stars with good (>3{sigma}) parallaxes, thereby effectively providing new parallaxes for these...
  • INT monitoring of Local Group. I. Andromeda I

    An optical monitoring survey in nearby dwarf galaxies was carried out with the 2.5m Isaac Newton Telescope. Fifty-five dwarf galaxies and four isolated globular clusters in the...
  • A comprehensive statistical study of gamma-ray bursts

    In order to obtain an overview of gamma-ray bursts (GRBs), we need a full sample. In this paper, we collected 6289 GRBs (from GRB 910421 to GRB 160509A) from the literature,...
  • Milky Way satellite census. I. DES & PS1

    We report the results of a systematic search for ultra-faint Milky Way satellite galaxies using data from the Dark Energy Survey (DES) and Pan-STARRS1 (PS1). Together, DES and...
  • Teff and metallicities of M dwarfs in APOGEE DR14

    M dwarfs have enormous potential for our understanding of structure and formation on both Galactic and exoplanetary scales through their properties and compositions. However,...
  • Hawaii infrared parallax program. II. Ultracool dwarfs

    We present a large, uniform analysis of young (~10-150Myr) ultracool dwarfs, based on new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (VL-G)...
  • PAndAS view of Andromeda satellites. II.

    We present a comprehensive analysis of the structural properties and luminosities of the 23 dwarf spheroidal galaxies that fall within the footprint of the Pan-Andromeda...
  • Photometric and kinematic properties of LPVs

    The table gives individual absolute K and IRAS 12 and 25 luminosities of 800 LPVs. They are obtained by applying the Luri-Mennessier (LM, see below) calibration method to a...
  • CaII-M_v_ Correlation (Wilson-Bappu Effect)

    Hipparcos parallaxes were used to derive absolute visual magnitudes of G, K, and M stars with Ca II emission line widths previously measured by O.C. Wilson. A linear...
