  • White dwarfs in LAMOST DR5

    In this paper, we report white dwarfs (WD) identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope (LAMOST), including spectral types of...
  • The bTFr of MIGHTEE-H I spiral galaxies

    Using a sample of 67 galaxies from the MeerKAT International GigaHertz Tiered Extragalactic Exploration Survey Early Science data, we study the H I-based baryonic Tully-Fisher...
  • Gamma-ray spectra of globular clusters in MW

    Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes -...
  • Blue straggler stars in open clusters with Gaia

    Blue straggler stars (BSSs) are the most massive stars in a cluster formed via binary or higher-order stellar interactions. Though the exact nature of such formation scenarios...
  • Stellar properties of KIC stars

    Investigations of the origin and evolution of the Milky Way disc have long relied on chemical and kinematic identifications of its components to reconstruct our Galactic past....
  • Mass and age of red giant branch stars

    Obtaining accurate and precise masses and ages for large numbers of giant stars is of great importance for unraveling the assemblage history of the Galaxy. In this paper, we...
  • Predicted properties for 468 RV planets

    The CHaracterizing ExOPlanets Satellite (CHEOPS) mission is planned for launch next year with a major objective being to search for transits of known radial velocity (RV)...
  • Stars with hot Jupiter exoplanets

    We present a grid of forward model transmission spectra, adopting an isothermal temperature-pressure profile, alongside corresponding equilibrium chemical abundances for 117...
  • TESS-HERMES Survey Data Release 1 catalog

    The Transiting Exoplanet Survey Satellite (TESS) will provide high-precision time series photometry for millions of stars with at least a half-hour cadence. Of particular...
  • Masses and ages of red giants

    We show that the masses of red giant stars can be well predicted from their photospheric carbon and nitrogen abundances, in conjunction with their spectroscopic stellar labels...
  • CSS detached eclipsing binaries

    Eclipsing binaries play pivotal roles in our understanding of stellar properties. In the era of all-sky surveys, thousands of eclipsing binaries have been charted, yet their...
  • ASAS, NSVS, and LINEAR detached eclipsing binaries

    Eclipsing binaries provide a unique opportunity to measure fundamental properties of stars. With the advent of all-sky surveys, thousands of eclipsing binaries have been...
  • CRTS close supermassive black hole binaries

    Hierarchical assembly models predict a population of supermassive black hole (SMBH) binaries. These are not resolvable by direct imaging but may be detectable via periodic...
  • White dwarf candidates using LAMOST DR3

    In previous work by Gentile Fusillo et al., we developed a selection method for white dwarf candidates which makes use of photometry, colours and proper motions to calculate a...
  • Distance-limited sample of MYSOs

    We analyse C^18^O (J=3-2) data from a sample of 99 infrared (IR)-bright massive young stellar objects (MYSOs) and compact HII regions that were identified as potential...
  • Fundamental parameters of Kepler stars

    We present a study of 33 Kepler planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual...
  • The massive star population of Cygnus OB2

    We have compiled a significantly updated and comprehensive census of massive stars in the nearby Cygnus OB2 association by gathering and homogenising data from across the...
  • Mass estimation for FGK stars

    Stellar evolutionary models simulate well binary stars when individual stellar mass and system metallicity are known. The mass can be derived directly from observations only in...
  • W UMa-type contact binaries ages and masses

    Recently, our understanding of the origin of W UMa-type contact binaries has become clearer. Initial masses of their components were successfully estimated by Yildiz and Dogan...
  • Initial masses of W UMa type contact binaries

    W UMa type binaries have two defining characteristics. These are (i) the effective temperatures of both components are very similar, and (ii) the secondary (currently less...
