FBS 10th list of red stars
A 10th list of late-type M and C stars found on plates of the First Byurakan Spectral Sky Survey in the -11{deg}<{delta}<-7{deg} belt within area of about 1070{deg}^2^ is... -
Properties of late-type stars in Kelper field
In recent years, there has been a push to understand how chemical composition affects the magnetic activity levels of main sequence low-mass stars. Results indicate that more... -
Extreme velocity stars in the Galaxy
Two decades on, the study of hypervelocity stars is still in its infancy. These stars can provide novel constraints on the total mass of the Galaxy and its Dark Matter... -
Abundances of FGK primary stars
Detailed chemical composition of stars is of prime interest for a range of topics in modern stellar astrophysics, such as the chemical evolution of the Galaxy or the formation,... -
Variable stars study with TESS
From sector 1-44 TESS observations, 19 new rapidly oscillating Ap (roAp) stars, 103 ostensibly non-peculiar stars with roAp-like frequencies, and 617 {delta} Scuti stars with... -
Local main-sequence stars with phot. metallicities
We present a catalogue of 551214 main-sequence stars in the local (d<2kpc) Galactic thick disk and halo, based on a search of stars with large proper motions (>40.0mas/yr)... -
Gaia DR2 giants in the Galactic dust I
We consider a complete sample of 101810 giants with Gaia Data Realease 2 (DR2) parallaxes {varpi} within the red clump domain of the Hertzsprung-Russell diagram in the space... -
TRAPPIST-South UCD Transit Survey
We conducted a global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey - a prototype of the SPECULOOS transit search conducted with the TRAPPIST-South robotic telescope... -
Stellar activity with LAMOST. III.
We present the results from a systematic study of temporal variation of stellar activity in young late-type stars. We used multi-epoch LAMOST (Large sky Area Multi-Object fiber... -
Asteroseismology of 36 Kepler subgiants. I.
The presence of mixed modes makes subgiants excellent targets for asteroseismology, providing a probe for the internal structure of stars. Here we study 36 Kepler subgiants with... -
Magnetic activity based on LAMOST and Kepler
Stellar magnetic activity is an interesting phenomenon in late-type stars. We use the medium-resolution spectroscopic observations of 406069 late-type stars from LAMOST to... -
Metallicity distribution in GC
We present stellar metallicity measurements of more than 600 late-type stars in the central 10pc of the Galactic Centre. Together with our previously published KMOS data, this... -
Kinematics of nearby young stars
In the last three decades several hundred nearby members of young stellar moving groups (MGs) have been identified, but there has been less systematic effort to quantify or... -
Characterization of LMC M-stars in the JWST era
We study the M-type asymptotic giant branch (AGB) population of the Large Magellanic Cloud (LMC) by characterizing the individual sources in terms of the main properties of the... -
Asteroseismology of luminous red giants with Kepler
While long-period variables (LPVs) have been extensively investigated, especially with MACHO and OGLE data for the Magellanic Clouds, there still exist open questions in their... -
DES Y3 substellar LT and M catalogs
In this paper we present a catalogue of 11745 brown dwarfs with spectral types ranging from L0 to T9, photometrically classified using data from the Dark Energy Survey (DES)... -
APOKASC Evolutionary state of red-giant stars
The internal working of low-mass stars is of great significance to both the study of stellar structure and the history of the Milky Way. Asteroseismology has the power to... -
First Byurakan Survey of Late-Type Stars - v2
A total of 18 lists of the First Byurakan Survey of Late-Type Stars (FBS LTS) were published between 1990 and 2016. The stars were found on FBS low-dispersion spectroscopic... -
Masses and radii of Kepler and CoRoT targets
Recently, by analysing the oscillation frequencies of 90 stars, Yildiz, Celik Orhan & Kayhan have shown that the reference frequencies ({nu}min0, {nu}min1, and {nu}min2)... -
Galactic disc enrichment with Mo and Ru
We present new observational data for the heavy elements molybdenum (Mo, Z=42) and ruthenium (Ru, Z=44) in F-, G-, and K-stars belonging to different substructures of the Milky...
