Temperatures of Kepler eclipsing binaries
We have combined the Kepler Eclipsing Binary Catalogue with information from the HES (Everett et al., 2012PASP..124..316E), KIS (Greiss et al, 2012AJ....144...24G, Cat.... -
Properties of KOI host stars
We report rotation periods, variability characteristics, gyrochronological ages for ~950 of the Kepler Object of Interest host stars. We find a wide dispersion in the amplitude... -
Kepler stars with infrared excess
We describe a search for infrared excess emission from dusty circumstellar material around 180000 stars observed by the Kepler and Wide-field Infrared Survey Explorer missions.... -
Cool stars in galactic clusters
We have investigated the relevant trend of the bolometric correction (BC) at the cool-temperature regime of red giant stars and its possible dependence on stellar metallicity.... -
Lower main-sequence stars fundamental param.
We derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the Infrared Flux Method to... -
{beta} Cephei pulsating variables from TESS and Gaia
{beta} Cephei pulsating variable (BCEP) stars are the most massive pulsating variable stars in the main sequence, exhibiting both p- and g-mode pulsations. In this study, we... -
Solar-like oscillators using TESS 2min cadence LCs
Based on all 2 minute cadence TESS light curves from Sector 1 to 60, we provide a catalog of 8651 solar-like oscillators, including frequency at maximum power ({nu}max, with its... -
Kinematics of young open clusters & O-B2-type stars
Using young open clusters and O-B2-type stars in Gaia Data Release 3, we investigate the kinematics of the local spiral structure. In general, the young sources in the outer... -
Slowly pulsating B stars from TESS, LAMOST & Gaia DR3
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have... -
In the Trenches of the solar-stellar connection. VII.
The Wilson-Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the CaII 3934{AA} K line and stellar absolute visual magnitude... -
OB-type pulsating stars with TESS, LAMOST & Gaia
O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from... -
Opt. spectra of blue MIR objects in LMC
We present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were... -
Kepler P<2d close binaries
Contact binary star systems represent the long-lived penultimate phase of binary evolution. Population statistics of their physical parameters inform an understanding of binary... -
Abundances of northern bright TESS stars
In fulfilling the aims of the planetary and asteroseismic research missions, such as that of the NASA Transiting Exoplanet Survey Satellite (TESS) space telescope, accurate... -
Spectroscopic binaries from LAMOST MRS. I.
We developed a convolutional neural network model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single-exposure medium-resolution spectra... -
Early-type star stellar rotations in LAMOST MRS. I.
We derive stellar parameters and abundances ("stellar labels") of 40034 late-B and A-type main-sequence stars extracted from the Large Sky Area Multi-Object Fiber Spectroscopic... -
High-resolution spectroscopy of TESS stars
Accurate atmospheric parameters and chemical composition of stars play a vital role in characterizing physical parameters of exoplanetary systems and understanding of their... -
RV photon limits of well-characterized F-M stars
The determination of extrasolar planet masses with the radial velocity (RV) technique requires spectroscopic Doppler information from the planet's host star, which varies with... -
Symbiotic stars with 2MASS, WISE & Gaia data
We present a new census of Galactic and extragalactic symbiotic stars (SySts). This compilation contains 323 known and 87 candidate SySts. Of the confirmed SySts, 257 are... -
Parallaxes of late-T and Y dwarfs
We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using observations from Spitzer (143), the U.S. Naval Observatory (18), the New Technology Telescope...
