The All-Sky Compiled Catalogue of 2501313 stars (ASCC-2.5) with the limiting magnitude V=12-14 is a result of a merging of star lists from present day large high-precision...

The catalog contains 6125 stars brighter than B=17.5, V=17.0 in the south galactic cap. The data have been obtained using the UK Schmidt telescope between 1975 and 1981. The...

We present and analyse a catalogue of 233 pulsars with proper motion measurements. The sample contains a wide variety of pulsars including recycled objects and those associated...

We present results of an analysis of a UV image in the direction of Ophiuchus, obtained with the FAUST instrument. The image contains 228 UV sources. Most of these are...

This paper continues kinematical investigation of the Hipparcos visual binaries with known orbits. A sample, consisting of 804 binary systems with orbital elements determined...

A sample consisting of 570 binary systems is compiled from several sources of visual binary stars with well-known orbital elements. High-precision trigonometric parallaxes (mean...

A complete accounting of nearby objects-from the highest-mass white dwarf progenitors down to low-mass brown dwarfs-is now possible, thanks to an almost complete set of...

{beta} Cephei pulsating variable (BCEP) stars are the most massive pulsating variable stars in the main sequence, exhibiting both p- and g-mode pulsations. In this study, we...

We combine photometric data from GALEX GR6+7 All-Sky Imaging Survey and Gaia Early Data Release 3 with stellar parameters from the SAGA and PASTEL catalogs to construct...

Using young open clusters and O-B2-type stars in Gaia Data Release 3, we investigate the kinematics of the local spiral structure. In general, the young sources in the outer...

We present spectroscopic data for 16369 stellar targets within and/or toward 38 dwarf spheroidal galaxies and faint star clusters within the Milky Way halo environment. All...

This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have...

Studying open clusters (OCs) may help to provide a comprehensive understanding of the structure and evolution of the Milky Way. Many previous studies have systematically...

O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from...

Open clusters (OCs) are regarded as tracers to understand stellar evolution theory and validate stellar models. In this study, we presented a robust approach to identifying OCs....

We systematically searched for open clusters in the solar neighborhood within 500pc using pyUPMASK and HDBSCAN clustering algorithms based on Gaia DR3. Taking into consideration...

We report 1,656 new star clusters found in the Galactic disk (|b|<20deg) beyond 1.2kpc, using Gaia EDR3 data. Based on an unsupervised machine learning algorithm, DBSCAN, and...

Although previous searches for star clusters have been very successful, many clusters are likely still omitted, especially at high Galactic latitude regions. In this work, based...

As part of the Bar and Spiral Structure Legacy (BeSSeL) Survey, we have used the Very Long Baseline Array (VLBA) to measure 16 trigonometric parallaxes and proper motions of...

We report 541 new open cluster candidates in Gaia EDR3 through revisit the cluster results from an earlier analysis of the Gaia DR2, which revealed near a thousand open cluster...
