  • APOGEE and Gaia DR2 analysis of IC 166

    IC 166 is an intermediate-age open cluster (OC) (~1 Gyr) that lies in the transition zone of the metallicity gradient in the outer disk. Its location, combined with our very...
  • APOGEE-2 survey of Orion Complex. II.

    We present an analysis of spectroscopic and astrometric data from APOGEE-2 and Gaia DR2 (Cat. I/345) to identify structures toward the Orion Complex. By applying a hierarchical...
  • The solar neighborhood. XLIII. New nearby stars

    We have conducted a novel search of most of the southern sky for nearby red dwarfs having low proper motions, with specific emphasis on those with {mu}<0.18"/yr, the lower...
  • Orbits of subsystems in six multiple stars. III.

    Spectroscopic orbits are computed for inner pairs in six nearby hierarchical multiple systems (HIP 35733, 95106/95110, 105441, 105585/105569, 105947, and 109951). Radial...
  • The stellar membership of the Taurus SFR

    The high-precision astrometry from the second data release of the Gaia mission (Cat. I/345) has made it possible to greatly improve the census of members of nearby clusters and...
  • California-Kepler Survey. VII. Planet radius gap

    The distribution of planet sizes encodes details of planet formation and evolution. We present the most precise planet size distribution to date based on Gaia parallaxes, Kepler...
  • Stellar properties for M dwarfs in MEarth-South

    Stellar rotation periods are valuable both for constraining models of angular momentum loss and for understanding how magnetic features impact inferences of exoplanet...
  • Solar neighborhood. XXXV. Distances to M dwarfs

    We present trigonometric, photometric, and photographic distances to 1748 southern ({delta}{<=}O{deg}) M dwarf systems with {mu}>=0.18''/yr, of which 1404 are believed to...
  • Gaia EDR3 new Galactic open clusters

    The astrometric satellite Gaia has recently released part of its third data set, which provides a good opportunity to hunt for more open clusters in the Milky Way. Here, we...
  • Membership and lithium of young clusters

    It is now well known that pre-main sequence models with inflated radii should be taken into account to simultaneously reproduce the colour-magnitude diagram and the lithium...
  • Structural parameters of 389 local open clusters

    The distribution of member stars in the surroundings of an Open Cluster (OC) can shed light on the process of its formation, evolution and dissolution. The analysis of...
  • Photometric and astrometric study of NGC 6530

    NGC 6530 is a young cluster, with a complex morphology and star-formation history. We present a statistical study of its global properties, using a new, large list of candidate...
  • The Sco OB2 population from Gaia DR2 data

    The Sco OB2 association is the nearest OB association, extending over approximately 2000 square degrees on the sky. Only its brightest and most massive members are already known...
  • Cepheid period-luminosity-metallicity relation

    We use parallax data from the Gaia second data release (GDR2), combined with parallax data based on HIPPARCOS and HST data, to derive the period-luminosity-metallicity (PLZ)...
  • 3D shape of Orion A from Gaia DR2

    We use the Gaia DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We...
  • Revised HIP periods for long-period variables

    We analyse the K-band luminosities of a sample of galactic long-period variables using parallaxes measured by the Hipparcos mission. The parallaxes are in most cases re-computed...
  • TESS Input Catalog version 8.2 (TIC v8.2)

    We define various types of "phantom" stars that may appear in the TESS Input Catalog (TIC), and provide examples and lists of currently known cases. We present a methodology...
  • TESS Input Catalog - v8.0 (TIC-8)

    The TIC is used to help identify two-minute cadence target selection for the Transiting Exoplanet Survey Satellite (TESS) mission, and to calculate physical and observational...
  • Classifier catalogue of class II YSO posteriors

    A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality...
  • Extended Hipparcos Compilation (XHIP)

    The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources....
