Tycho-2 red giant branch and carbon stars
Based on multicolor photometry from the 2MASS and Tycho-2 catalogues, we have produced a sample of 38368 branch red giants that has less than 1% of admixtures and is complete... -
Red giant clump in the Tycho-2 catalog
The Tycho-2 proper motions and Tycho-2 and 2MASS photometry are used to select 97348 red giant clump (RGC) stars. The interstellar extinction and photometric distance are... -
Evryscope-South survey
Using photometric data collected by Evryscope-South, we search for nearby young variable systems on the upper main sequence (UMS) and pre-main sequence (PMS). The Evryscopes are... -
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... -
WR central stars and their host PN
We address the physical and kinematical properties of Wolf-Rayet [WR] central stars (CSs) and their host planetary nebulae (PNe). The studied sample comprises all [WR] CSs that... -
K giant stars along Sagittarius streams
The Large Sky-Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 3 provided 341 691 K giant stars with stellar parameters. Based on the models of Law &... -
YSOs in GRSMC 045.49+00.04 from IR obs.
Understanding the characteristics of young stellar populations is essential for deriving insights into star formation processes within parent molecular clouds and the influence... -
NIR-FIR phot. of YSOs in 2 UC HII regions
Ultra-compact H II (UC HII) regions are an important phase in the formation and early evolution of massive stars and a key component of the interstellar medium (ISM). The main... -
High-mass star formation evolutionary trends
ATLASGAL is an 870um dust survey of 420deg^2^ the inner Galactic plane and has been used to identify ~10000 dense molecular clumps. Dedicated follow-up observations and... -
Element abundances study of Cepheids
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their... -
Distances of local galaxies
Any calibration of the present value of the Hubble constant (H_0_) requires recession velocities and distances of galaxies. While the conversion of observed velocities into true... -
Pristine Inner Galaxy Survey PIGS VIII
The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge.... -
OB stars and associations in Auriga
OB associations are important probes of recent star formation and Galactic structure. In this study, we focus on the Auriga constellation, an important region of star formation... -
Reduced proper motion with Gaia DR3
With the advent of the European Space Agency's Gaia mission and its recent data releases EDR3 and DR3, the astronomy community has obtained the largest-ever cartograph of our... -
Data on 197 SNe Ia and their 196 hosts
In this Letter, using classified 197 supernovae (SNe) Ia, we perform an analysis of their height distributions from the disc in edge-on spirals and investigate their light-curve... -
Gaia view of the Cepheus OB2
OB associations, birthplaces of the most luminous stars, are key objects for understanding the formation of high-mass stars and their effects on their environments. The aim of... -
Pristine survey. XX.
Ultra metal-poor stars ([Fe/H]<-4.0) are very rare, and finding them is a challenging task. Both narrow-band photometry and low-resolution spectroscopy have been useful tools... -
Young intermediate-mass stars stellar param.
Intermediate-mass stars (IMSs) represent the link between low-mass and high-mass stars, and cover a key mass range for giant planet formation. In this paper, we present a... -
Benchmarking MESA isochrones with the Hyades
Based on GAIA EDR3, we revisit and update our sample of bonafide single stars in the Hyades open cluster. The small observational uncertainties in parallax and photometry 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...
