OB associations from LAMOST DR7 & Gaia DR3
OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution,... -
Eclipsing binaries from LAMOST DR10, TESS and VSX
In this study, we present a comprehensive study of more than 50000 spectra of 32257 eclipsing binaries from the LAMOST DR10 survey, including 5200 systems with spectroscopy. We... -
The value-added cat. of OB stars in LAMOST DR7
In this work, we update the catalog of OB stars based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope data release 7 and modify the OB stars' selection criteria... -
Massive stars in nearby galaxies
Mass loss is a key aspect of stellar evolution, particularly in evolved massive stars, yet episodic mass loss remains poorly understood. To investigate this, we need evolved... -
Photometry and spectroscopy in IC 2391
We present the stellar and substellar mass function (MF) of the open cluster IC 2391, plus its radial dependence, and use this to put constraints on the formation mechanism of... -
Candidate red supergiants from Gaia DR3
Our position within the Galactic plane and the dust obscuration make it challenging to retrieve a true picture of the Milky Way's morphology. While the Milky Way has been... -
ASAS-SN bright supernova catalogue 2018-2020
We catalogue the 443 bright supernovae (SNe) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) in 2018-2020 along with the 519 SNe recovered by ASAS-SN and 516... -
9Msun ultramassive WD stars progenitor
We study the full evolution of a 1.313M_{sun} white dwarf star that descended from a 9M{sun} main-sequence progenitor with an initial metallicity of Z=0.02. Using MESA... -
Variables and sdBs stars in NEH/SEH TESS FFI III
We present an update on the variable star survey performed on the TESS 30 min Full Frame Image (FFI) data reported by our first two papers in this series. This update includes a... -
M-type T Tauri stars with LAMOST DR8, Gaia & WISEA
The full disk, full of gas and dust, determines the upper limit of planet masses, and its lifetime is critical for planet formation, especially for giant planets. In this work,... -
O5 through L3 empirical stellar spectra from SDSS
We present a library of empirical stellar spectra created using spectra from the Sloan Digital Sky Survey's Baryon Oscillation Spectroscopic Survey. The templates cover spectral... -
The Henry Draper Catalog with Gaia IDs
This is the Henry Draper catalog (HD, Cannon & Pickering 1918-1924) as distributed by the Astronomical Data Center in 1989 (Vizier III/135A), with Gaia DR2 source_ids and... -
Galactic novae distances and properties
I derive the overall best distances for all 402 known Galactic novae, and I collect their many properties. The centrepiece is the 74 novae with accurate parallaxes from the new... -
Spectroscopy study of nearby LOFAR M dwarfs
Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such... -
Hot subluminous stars 500pc volume-limited sample
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax... -
The DEBCat detached eclipsing binary catalogue
Detached eclipsing binary star systems are our primary source of measured physical properties of normal stars. I introduce DEBCat: a catalog of detached eclipsing binaries with... -
Extended Hipparcos Compilation (XHIP)
The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources.... -
Spectral properties of 441 radio pulsars
We present a study of the spectral properties of 441 pulsars observed with the Parkes radio telescope near the centre frequencies of 728, 1382 and 3100MHz. The observations at... -
NIR spectroscopy of Galactic WR stars. III
A new method of image subtraction is applied to images from a J, K, and narrow-band imaging survey of 300 deg2 of the plane of the Galaxy, searching for new Wolf-Rayet (WR)... -
Lithium abundance of solar-like stars
We report on the determination of the lithium abundance [A(Li)] of 52 solar-like stars. For 41 objects the A(Li) here presented corresponds to the first measurement. We have...
