Membership of variable stars in Galactic GC
We have performed a critical evaluation of the membership status of all variable stars in globular clusters recorded in the Catalogue of Variable Stars in Globular Clusters... -
Infrared properties of carbon stars in our Galaxy
We explore the characteristics of carbon stars within our Galaxy through a comprehensive analysis of observational data spanning visual and infrared (IR) bands. Leveraging data... -
Planetary systems study with GALAH surveys
Pioneering photometric, astrometric, and spectroscopic surveys is helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy and the... -
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... -
SHBoost 2024
With Gaia Data Release 3 (DR3), new and improved astrometric, photometric, and spectroscopic measurements for 1.8 billion stars have become available. Alongside this wealth of... -
Restricted sample of Gaia-ESO open clusters
Recent evidence from spectroscopic surveys points towards the presence of a metal-poor, young stellar population in the low-alpha, chemically thin disk. In this context, the... -
Cetus stream non-LTE abundance analysis
Dwarf galaxy streams encode rich information that is essential to understand early galaxy formation and nucleosynthesis channels. Due to various timescales of star formation... -
2nd Epoch Molonglo Galactic Plane Survey (MGPS-2)
The MGPS-2 (second epoch Molonglo Galactic Plane Survey) was carried out with the Molonglo Observatory Synthesis Telescope at a frequency of 843MHz and with a restoring beam of... -
Composite CO Survey of the Milky Way
This survey consists of CO(J=1-0) (115 GHz) spectra for the entire Galactic plane. The latitude coverage varies with longitude and in some regions extends from -25 degrees to... -
Classifier catalogue of class II YSO posteriors
A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality... -
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... -
IGAPS. merged IPHAS and UVEX of northern Galactic plane
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003... -
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.... -
Photometry and Spectroscopy for Luminous Stars
This catalogue supersedes the previous version (VI/92). The last update is 01 July 2005. This project originated in the summer of 1991 when the author began compiling a... -
3D map of reddening and interstellar extinction
An improved version of the 3D stellar reddening map in a space with a radius of 1200 pc around the Sun and within 600 pc of the Galactic midplane is presented. As in the... -
Dispersion measure of Milky Way and MC pulsars
A number of recent studies indicates a significant amount of ionized gas in a form of the hot gas halo around the Milky Way. The halo extends over the region of 100 kpc and may... -
Galactic kinematics from YSOs sample
Based on published sources, we have created a kinematic database on 220 massive (>10M_{sun}) young Galactic star systems located within <3 kpcof the Sun. Out of them,... -
