  • FGK dwarfs from LAMOST DR7 and Gaia DR3 and Kepler

    The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog,...
  • Masses of OB-type stars from LAMOST DR5

    The measurements of masses and luminosities of massive stars play an important role in understanding the formation and evolution of their host galaxies. In this work, we present...
  • 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...
  • Exoplanets parameters

    The number of discovered exoplanets now exceeds 5500, allowing statistical analyses of planetary systems. Multi-planet systems are mini-laboratories of planet formation and...
  • Young low-mass stars population in Trumpler 14

    Massive star-forming regions are thought to be the most common birth environments in the Galaxy and the only birth places of very massive stars. Their presence in the stellar...
  • Planetary formation & evolution in stellar clusters .I

    Planets in young star clusters could shed light on planet formation and evolution since star clusters can provide accurate age estimation. However, the number of transiting...
  • Blazars properties

    We analyzed the relationship between several basic parameters describing supermassive black holes such as jet power, black hole spin, accretion disk magnetic field, black hole...
  • Rot. distributions from TESS-APOGEE-Kepler-Gaia

    Stellar rotation is a complex function of mass, metallicity, and age and can be altered by binarity. To understand the importance of these parameters in main-sequence stars, we...
  • VANDAM survey of Orion protostars. VI. Disks

    We present Markov Chain Monte Carlo radiative transfer modeling of a joint ALMA 345GHz and spectral energy distribution data set for a sample of 97 protostellar disks from the...
  • Pre- and main sequence stars properties

    The demographics of young exoplanets can shed light on their formation and evolution processes. Exoplanet properties are derived from the properties of their host stars. As...
  • Properties of 600 bona fide stars in the Hyades

    The determination of the astrophysical properties of stars remains challenging and frequently relies on the application of stellar models. Stellar sequences in nearby open...
  • The KGPS. I. Kepler planet-host RVs from HIRES

    Despite the importance of Jupiter and Saturn to Earth's formation and habitability, there has not yet been a comprehensive observational study of how giant exoplanets correlate...
  • Galactic LMXBs catalog

    Low-mass X-ray binaries (LMXBs) are high-energy sources that require multi-wavelength follow-up campaigns to be fully characterised. New transients associated with LMXBs are...
  • Age estimations of low-mass TESS CVZ stars

    The number of potentially habitable planets continues to increase, but we lack the time and resources to characterize all of them. With ~30 known potentially habitable planets...
  • Ages, masses & kinematics of GALAH MS turnoff stars

    Main-sequence turnoff (MSTO) stars are good tracers of Galactic populations since their ages can be reliably estimated from atmospheric parameters. Based on the GALAH survey, we...
  • New mean motion resonances with exoMMR package

    The study of orbital resonances allows for the constraint of planetary properties of compact systems. We can predict a system's resonances by observing the orbital periods of...
  • M dwarfs in the Pleiades

    Rotation periods obtained with the Kepler satellite have been combined with precise measurements of projected rotation velocity from the WIYN 3.5-m telescope to determine the...
  • Stellar companions of exoplanet host stars

    Stellar multiplicity is a key aspect of exoplanet diversity, as the presence of more than one star in a planetary system can have both devastating and positive effects on its...
  • SB9 orbits with HERMES/Mercator RVs

    The Gaia mission is delivering a large number of astrometric orbits for binary stars. By combining these with spectroscopic orbits for systems with two observable spectra (SB2),...
