Photometric and Spectroscopic Databases for LSS Stars
This catalog contains databases of published photoelectric UBVbeta data, MK-system spectral classifications, and Stroemgren four-color uvby photometry for objects in the... -
Proper motions of faint UV-bright sources
Proper motions with values >=10 or <=10mas/yr have been extracted from the USNOB1.0 and Tycho2 catalogs for all Lanning UV-bright sources identified in the Sandage... -
Galactic plane VERA survey
In order to search for new VLBI sources in the galactic plane that can be used as phase reference sources in differential VLBI, we conducted 22GHz observations of radio sources... -
Scattered Star Group in the Orion A
Using Gaia DR3 data, we identified an extended (~60pc) group of stars sharing common motion but scattered in space, including from 150 to 300 probable members, named Group V. It... -
Galaxy halo Extremely Metal-Poor stars
In this work, we combine spectroscopic information from the SkyMapper survey for Extremely Metal-Poor stars and astrometry from Gaia DR2 to investigate the kinematics of a... -
Membership probabilities of 6 open cluster
Open clusters are central elements of our understanding of the Galactic disc evolution, as an accurate determination of their parameters leads to an unbiased picture of our... -
Gaia DR2 Galactic bulge new star clusters
We report the discovery of 34 new open clusters and candidates as a result of a systematic search carried out in 200 adjacent fields of 1x1 square degrees area projected towards... -
Compact radio sources in the SCORPIO field
We present observations of a region of the Galactic plane taken during the Early Science Program of the Australian Square Kilometre Array Pathfinder (ASKAP). In this context, we... -
Action-space clustering on stellar stream data
Stream stars removed by tides from their progenitor satellite galaxy or globular cluster act as a group of test particles on neighbouring orbits, probing the gravitational field... -
Period-luminosity-metallicity relation of RRLs
This paper presents results from photometric and statistical-parallax analysis of a sample of 850 field RR Lyrae (RRL) variables. The photometric and spectroscopic data for our... -
Evolutionary traits for stellar phylogeny
Since chemical abundances are inherited between generations of stars, we use them to trace the evolutionary history of our Galaxy. We present a robust methodology for creating a... -
Giant stars in TESS continuous viewing zones
The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We... -
SuperWASP variable stars
We present the first analysis of results from the SuperWASP variable stars Zooniverse project, which is aiming to classify 1.6 million phase-folded light curves of candidate... -
COMBS Survey. Metal-poor bulge stars
The metal-poor stars in the bulge are important relics of the Milky Way's formation history, as simulations predict that they are some of the oldest stars in the Galaxy. In... -
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... -
Temperature and metallicity scale of cool giants
We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the K band for stellar population studies. In this study,... -
[Fe/H] dependence of the wide-binary fraction
The metallicity dependence of the wide-binary fraction (WBF) IN stellar populations plays a critical role in resolving the open question of wide-binary formation. In this paper,... -
The Swift Bulge Survey. first X-ray results
Very faint X-ray transients (VFXTs) are X-ray transients with peak X-ray luminosities (L_X_) of L_X_~<10^36^erg/s, which are not well understood. We carried out a survey of... -
Stars in the Sagittarius stream
We assemble a catalogue of candidate Sagittarius stream members with 5D and 6D phase-space information, using astrometric data from Gaia DR2, distances estimated from RR Lyrae... -
S2 stream. Shreds of a primitive dwarf galaxy
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream....
