A comprehensive photometric and kinematical characteristic of the newly discovered QCs clusters with Gaia EDR3
Elsanhoury, W. H.; Haroon, A. A.; Amin, Magdy Y. +1 more
This study reports the first comprehensive astrometric, photometric, and kinematical analysis of four newly discovered open clusters; namely QC1, QC2, QC3, and QC4, using astrometric and photometric data from the most recent Gaia EDR3 for
Deep V and I CCD photometry of young star cluster NGC 1893 with the 3.6m DOT
Pandey, S. B.; Panwar, Neelam; Kumar, Amit
Young star clusters consisting of massive stars are the ideal sites to study the star formation processes and influence of massive stars on the subsequent star formation. NGC 1893 is a young star cluster associated with the HII region Sh2-236. It contains about five 'O'-type stars and several early 'B'-type stars. It is located at a moderate dista…
Optical observations of star clusters NGC 1513 and NGC 4147; white dwarf WD 1145+
Yadav, R. K. S.; Pandey, S. B.; Sharma, Saurabh +3 more
The UBVRI CCD photometric data of open star cluster NGC 1513 are obtained with the 3.6-m Indo-Belgian Devasthal optical telescope (DOT). Analyses of the GAIA EDR3 astrometric data have identified 106 possible cluster members. The mean proper motion of the cluster is estimated as
Fundamental parameters of barium and CH stars from asteroseismic analysis: HD 33409, HD 20084 and HD 66812
Goswami, Aruna; Sonamben, Mayani
Asteroseismic analysis of stars using space mission data, such as the transiting exoplanet survey satellite (TESS) allows us to derive accurate fundamental parameters of stars. Barium and CH stars are believed to be in binary systems with a now invisible white dwarf companion. Knowledge of accurate fundamental parameters of these stars is essentia…

Mass function of understudied open clusters NGC 2254 and Mayer 2
Kowshik, Krishna Kumar; Sujatha, S.; Komala, S. +1 more
The results of the CCD photometric UBVRI observations of the open clusters NGC 2254 and Mayer 2 are presented in this article. These clusters were observed using the 2-metre Himalayan Chandra Telescope at Hanle, India. NGC 2254 is located in the direction of Monoceros constellation at a distance of 2.57 ± 0.2 kpc and Mayer 2 is located in the dire…
