  • Giant Outer Transiting Exoplanet Mass survey. IV.

    Discovering and characterizing exoplanets at the outer edge of the transit method's sensitivity has proven challenging owing to geometric biases and the practical difficulties...
  • Giant Outer Transiting Exoplanet Mass Survey. III.

    Large-scale exoplanet surveys like the Transiting Exoplanet Survey Satellite (TESS) mission are powerful tools for discovering large numbers of exoplanet candidates....
  • He-rich hot subdwarf stars from LAMOST and Gaia DR3

    We conducted an analysis of the abundances of He, C, and N in 210 He-rich hot subdwarfs observed within both the Gaia Data Release 3 (DR3) and LAMOST DR7 data sets. This...
  • Architectures of S* Transiting Planets in Binaries.I.

    The effect of stellar multiplicity on planetary architecture and orbital dynamics provides an important context for exoplanet demographics. We present a volume-limited catalog...
  • TOI-1994 radial velocities with MINERVA & CHIRON

    We present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of...
  • 2MASS bright galaxies HI ZoA survey

    To complement the 2MASS Redshift Survey (2MRS) and the 2MASS Tully-Fisher survey (2MTF) a search for 21cm HI line emission of 2MASS bright galaxy candidates has been pursued...
  • HD 77946 RV curves

    We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 (M=1.17M_{sun}_, R=1.31R_{sun}) star, which hosts a transiting planet recently...
  • Gaia-ESO Survey: members of 32 open clusters

    The Gaia-ESO Survey (GES) observed many open clusters as part of its programme to spectroscopically characterize the various Milky Way populations. GES spectroscopy and Gaia...
  • Radial velocities in M67. I. 1278 candidate members

    We present results from 13776 radial-velocity (RV) measurements of 1278 candidate members of the old (4Gyr) open cluster M67 (NGC 2682). The measurements are the results of a...
  • Solar neighborhood. XXXIII. 45 M dwarfs

    We present basic observational data and association membership analysis for 45 young and active low-mass stellar systems from the ongoing Research Consortium On Nearby Stars...
  • RAdial Velocity Experiment: RAVE DR5

    The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...
  • RAVE DR5 Cone Search

    The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical...
  • Kepler-105 radial velocity follows up

    An intriguing pattern among exoplanets is the lack of detected planets between approximately 1.5R{Earth} and 2.0R{Earth}. One proposed explanation for this "radius gap" is the...
  • Catalog of 519 high velocity stars (HiVels)

    Utilizing astrometric parameters sourced from Gaia Data Release 3 and radial velocities obtained from various spectroscopic surveys, we identify 519 high-velocity stars (HiVels)...
  • TESS-Keck Survey. XVII. TOI-1136 radial velocities

    We present a radial velocity (RV) analysis of TOI-1136, a bright Transiting Exoplanet Survey Satellite (TESS) system with six confirmed transiting planets, and a seventh...
  • Photometry of stars within 3.2' from BH 261

    The Milky Way Bulge extra-tidal star survey is a spectroscopic survey with the goal of identifying stripped globular cluster stars from inner Galaxy clusters. In this way, an...
  • Wolf 359 Keck/HIRES & MAROONX radial velocity

    Wolf-359 (CN-Leo, GJ-406, Gaia-DR3-3864972938605115520) is a low-mass star in the fifth-closest neighboring system (2.41pc). Because of its relative youth and proximity,...
  • Dormant 33 solar-masses black hole

    We announce the serendipitous discovery of a nearby (590pc) binary system composed of an old very metal-poor giant star orbiting a black hole with an estimated mass of...
  • 3D morphology of open clusters with Gaia EDR3. II.

    We identify members of 65 open clusters in the solar neighborhood using the machine-learning algorithm StarGO based on Gaia EDR3 data. After adding members of 20 clusters from...
  • Very metal-poor stars with LAMOST & Subaru. I.

    The chemical abundances of very metal-poor stars provide important constraints on the nucleosynthesis of the first generation of stars and early chemical evolution of the...
