XHIP: An extended hipparcos compilation

  title={XHIP: An extended hipparcos compilation},
  author={Erik Anderson and Charles Francis},
  journal={Astronomy Letters},
We present the Extended Hipparcos Compilation (XHIP), a database of all stars in the New Reduction of the Hipparcos Catalog extensively cross-referenced with data from a broad survey of presently available sources. The resulting collection uniquely assigns 116 096 spectral classifications, 46 392 radial velocities, and 18 549 homogenized iron abundances [Fe/H] to Hipparcos stars. Stellar classifications from SIMBAD, indications of multiplicity from CCDM or WDS, stellar ages from the Geneva… 

Search for kinematic siblings of the sun based on data from the XHIP catalog

From the XHIP catalogue, we have selected 1872 F-G-K stars with relative parallax measurement errors <20% and absolute values of their space velocities relative to the Sun <15 km s−1. For all these

A Catalog of Stellar Unified Properties (CATSUP) for 951 FGK-Stars within 30 pc

Almost every star in our Galaxy is likely to harbor a terrestrial planet, but accurate measurements of an exoplanet’s mass and radius demand accurate knowledge of the properties of its host star. The

Erratum: “The Hipparcos–Gaia Catalog of Accelerations” (2018, ApJS, 239, 31)

We correct an error in the calculation of the perspective acceleration in R.A. of the published catalog (nonlinear_dpmra in the catalog). The error was due to an inconsistency in the computation of


Age determination is undertaken for nearby early type (BAF) stars, which constitute attractive targets for high-contrast debris disk and planet imaging surveys. Our analysis sequence consists of

A Search for Exoplanets around Northern Circumpolar Stars. IV. Six Planet Candidates to the K Giants, HD 44385, HD 97619, HD 106574, HD 118904, HD 164428, and HD 202432

We report the discovery of long-period radial velocity (RV) variations in six intermediate-mass K-giant stars using precise RV measurements. These discoveries are part of the Search for Exoplanets

The VLT/NaCo large program to probe the occurrence of exoplanets and brown dwarfs in wide orbits - I. Sample definition and characterization

Context. Young, close stars are ideal targets for searching planets using the direct imaging technique. The determination of stellar parameters is crucial for the interpretation of imaging survey

XHIP-II: Clusters and associations

To find improved candidate lists for clusters and associations represented among Hipparcos stars, to establish distances, and to cast light on the Pleiades distance anomaly, a six dimensional fitting procedure is used.

Fundamental parameters and infrared excesses of Tycho–Gaia stars

Effective temperatures and luminosities are calculated for 1,475,921 Tycho-2 and 107,145 Hipparcos stars, based on distances from Gaia Data Release 1. Parameters are derived by comparing

Close encounters of the stellar kind

Stars which pass close to the Sun can perturb the Oort cloud, injecting comets into the inner solar system where they may collide with the Earth. Using van Leeuwen's re-reduction of the Hipparcos

Stellar diameters and temperatures - V. 11 newly characterized exoplanet host stars

We use near-infrared interferometric data coupled with trigonometric parallax values and spectral energy distribution fitting to directly determine stellar radii, effective temperatures and



Kinematics of Metal-poor Stars in the Galaxy. II. Proper Motions for a Large Nonkinematically Selected Sample

We present a revised catalog of 2106 Galactic stars, selected without kinematic bias and with available radial velocities, distance estimates, and metal abundances in the range -4.0 ≤ [Fe/H] ≤ 0.0.

Pulkovo Compilation of Radial Velocities for 35 495 Hipparcos stars in a common system

The Pulkovo Compilation of Radial Velocities (PCRV) has been made to study the stellar kinematics in the local spiral arm. The PCRV contains weighted mean absolute radial velocities for 35 495

Early Evolution of the Galactic Halo Revealed from Hipparcos Observations of Metal-poor Stars

The kinematics of 122 red giant and 124 RR Lyrae stars in the solar neighborhood are studied using accurate measurements of their proper motions obtained by the Hipparcos astrometry satellite,

Radial velocities - IX. Measurements of 2800 B2-F5 stars for Hipparcos

Radial velocities have been determined for a sample of 2930 B2-F5 stars, 95% observed by the Hipparcos satellite in the north hemisphere and 80% without reliable radial velocity up to now.

A Spectroscopic Survey of the Youngest Field Stars in the Solar Neighborhood. II. The optically faint sample

Star formation in the solar neighborhood is mainly traced by young stars in open clusters, associations and in the field, which can be identified by their X-ray emission. The determination of stellar
