KPD UV-excess objects
A survey for ultraviolet-excess objects has been performed for over about 1000sq.deg of the Galactic plane. Photographic blue and ultraviolet plates were obtained to select... -
SpeX survey on M dwarfs and giant planets
We investigate the stellar metallicity ([Fe/H] and [M/H]) dependence of giant planets around M dwarfs by comparing the metallicity distribution of 746 field M dwarfs without... -
PS1-MDS supernovae classifications
With the advent of the Vera C. Rubin Observatory, the discovery rate of supernovae (SNe) will surpass the rate of SNe with real time spectroscopic follow-up by 3 orders of... -
Kinematics of YSOs from Gaia DR3 and APOGEE
Based on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby... -
Galactic O-type stars with IACOB, GOSSS and TESS
In order to explore how the ubiquitous stochastic low-frequency (SLF) variability of O-type stars is related to various stellar characteristics, we compiled a sample of 150... -
X-ray obs. of potential host star's HZ
Stellar X-ray and UV radiation can significantly affect the survival, composition, and long-term evolution of the atmospheres of planets in or near their host star's habitable... -
Survey of faint compact objects
We present results from a low-resolution (73A) spectroscopic survey of faint compact objects conducted with the Low Dispersion Survey Spectrograph at the Anglo-Australian... -
Photometry of stars around NGC 7023
Interstellar extinction is investigated in a 1.5 square degree area in the direction of the reflection nebula NGC7023 at l=104.1{deg}, b=+14.2{deg}. The study is based on... -
F, G and K dwarf stars of the Pleiades

YSO candidates from LAMOST LRS DR9 & ZTF
As astronomical data sets become too large for traditional analysis approaches, more machine-learning algorithms are employed in astronomy. A wealth of light variation data 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... -
LAMOST DR9 M-giant stars value-added cat.
In this work, we update the catalog of M-giant stars from the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 9.... -
Am stars selected in LAMOST DR8-DR10
A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope... -
Stellar sp. libraries in Opt-NIR. I. UVES-POP
We present reprocessed flux-calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025nm, which can be used for stellar population... -
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... -
Spectroscopic data of TESS objects with LAMOST
Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar... -
Spectrophotometry of standard stars
We calibrate spectrophotometric optical spectra of 32 stars commonly used as standard stars, referenced to 14 stars already on the Hubble Space Telescope-based CALSPEC flux... -
Kepler eclipsing binaries with Gaia data
The O'Connell effect --the presence of unequal maxima in eclipsing binaries-- remains an unsolved riddle in the study of close binary systems. The Kepler space telescope... -
Exoplanet host stars from LAMOST, TESS, Kepler & K2
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) low- and medium-resolution spectroscopic surveys are important for determination of the orbital parameters and... -
Dust extinction law in nearby galaxies. II. M33
The dust extinction curves toward individual sight lines in M33 are derived for the first time with a sample of reddened O-type and B-type supergiants obtained from the Local...
