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.... -
New spectral types for Tycho2 stars
We compare the spectroscopic and trigonometric parallaxes of common stars from the Tycho-2 Spectral Type and Hipparcos Catalogues. This comparison has revealed that the distance... -
Spitzer solar-type stars list
We provide an overview of the Spitzer Legacy Program, Formation and Evolution of Planetary Systems, that was proposed in 2000, begun in 2001, and executed aboard the Spitzer... -
Subaru NIR obs. of Pleiades stars in SEEDS survey
We find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the... -
CPASJ1 position corrections
Using the data observed with the Photoelectric Astrolabe Mark II (PA II) of the Beijing Astronomical Observatory during the period from Feb. 1992 to Oct. 1993 in San Juan of... -
FBS 11th list of late-type stars
The eleventh list of faint late M and carbon type stars detected on the plates of the First Byurakan Spectral Survey in zone -7{deg}<={delta}<=-3{deg} and covering about... -
M stars in Cepheus region
The results of a spectral classification of 257 M stars observed in the Cepheus region are given. Their equatorial coordinates, photographic stellar magnitudes, and spectral... -
FBS 12th list of late-type stars
The twelfth list of faint late M and carbon type stars detected on the plates of the First Byurakan Spectral Survey in zone -30{deg}<={delta}<=1{deg} covering about 1070... -
40 parsec sample of white dwarfs from Gaia
We present a comprehensive overview of a volume-complete sample of white dwarfs located within 40 pc of the Sun, a significant proportion of which were detected in Gaia Data... -
TMTS flare study from the first two years
Tsinghua University-Ma Huateng Telescopes for Survey (TMTS) aims to detect fast-evolving transients in the Universe, which has led to discovery of thousands of short period... -
Hydrogen-deficient carbon stars spectra
Stellar spectral classification has been highly useful in the study of stars. While there is a currently accepted spectral classification system for carbon stars, the subset of... -
Classification of the 100pc WDs
The third data release of Gaia has provided low-resolution spectra for ~100000 white dwarfs (WDs) that, together with the excellent photometry and astrometry, represent an... -
Gaia white dwarfs within 40pc. III
We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of these 244 are in the Southern hemisphere. Observations were performed mostly with the... -
+150 OB stars in Sextans A
Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early galaxies. These stars... -
New classical Ae stars using LAMOST DR5
We report the first systematic study to identify and characterize a sample of classical Ae stars in the Galaxy. The spectra of these stars were retrieved from the A-star... -
Ultracool dwarfs in ALHAMBRA and COSMOS
Ultracool dwarfs (UCDs) encompass a wide variety of compact stellar-like objects with spectra classified as late-M, L, T, and Y. Most of them have been discovered using... -
Optical spectroscopy of classical Be stars
In this study, we analyse the emission lines of different species present in 118 Galactic field classical Be stars in the wavelength range of 3800-9000{AA}. We re-estimated the... -
2D kinematics of massive stars
The presence of massive stars (MSs) in the region close to the Galactic Centre (GC) poses several questions about their origin. The harsh environment of the GC favours specific... -
Search for variable subdwarf B stars in TESS I
We report the results of our search for pulsating subdwarf B stars in full frame images, sampled at 30 min cadence and collected during Year 1 of the TESS mission. Year 1 covers...
