LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee
Meenakshi Purandardas, Aruna Goswami, J. Shejeelammal +5
We present the results of the high-resolution (R60,000) spectroscopic analysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the list of carbon stars of LAMOST…
Optical Observations of star clusters NGC 1513 and NGC 4147; white dwarf WD1145+017 and band imaging of star forming region Sh2-61 with the 3.6 meter Devasthal Optical Telescope
Ram Sagar, R. K. S. Yadav, S. B. Pandey +3
The 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 dat…
Census of young stellar population in the Galactic H II region Sh2-242
Alik Panja, Soumen Mondal, Somnath Dutta +3
We present here identification and characterization of the young stellar population associated with an active star-forming site Sh2-242. We used our own new optical imaging and spe…
Optical Photometric Variable Stars towards the Galactic \hii region NGC 2282
Somnath Dutta, Soumen Mondal, Santosh Joshi +3
We report here CCD -band time-series photometry of a young (25 Myr) cluster NGC 2282 to identify and understand the variability of pre-main-sequence (PMS) stars. The -band…
Study of open clusters within 1.8 kpc and understanding the Galactic structure
Yogesh C. Joshi, Andrei Dambis, Anil K. Pandey +1
Based on an almost complete sample of Galactic open star clusters within 1.8 kpc, we perform a comprehensive statistical analysis of various cluster parameters like spatial positio…
Population I Cepheids and understanding star formation history of the Small Magellanic Cloud
Yogesh C. Joshi, Auro Mohanty, Santosh Joshi
In this paper, we study the age and spatial distributions of Cepheids in the Small Magellanic Cloud (SMC) as a function of their ages using the data from the OGLE III photometric c…
