Multiwavelength Study of Blue Straggler Stars in Tombaugh 2: Evidence for Binary Mass Transfer and Constraints on Cluster Dynamical State
D. Bisht, Ing-Guey Jiang, K. Belwal +7
We present a focused multiwavelength study of blue straggler stars (BSSs) in the intermediate-age open cluster Tombaugh 2, located in the outer Galactic disk, to constrain the domi…
Detection of young massive white dwarfs in core-collapsed globular cluster NGC 362
R. K. S. Yadav, Arvind K. Dattatrey, Annapurni Subramaniam +2
Core-collapsed globular clusters are ideal targets to explore the presence of stellar collision products. Here, we have studied seventeen FUV bright white dwarf members in the glob…
Spectroscopic Study of Blue Straggler Stars in the Globular Cluster NGC 3201
Gourav Kumawat, Arvind K. Dattatrey, R. K. S Yadav
We conducted a spectroscopic study of 39 blue straggler stars in the globular cluster NGC 3201. The spectra of these stars were collected from the literature. We determined the rad…
Investigating open cluster King 6: Detection of three new variables
Vaibhav Kumar Pandey, Arvind K Dattatrey, Apara Tripathi +2
This study presents photometric analysis of the intermediate-age open cluster King 6, utilizing photometric data in UBV(RI) passband and data from the 2MASS mission. The Gaia D…
UOCS XIII. Study of the FUV bright stars in the open cluster NGC 2420 using ASTROSAT
R. K. S. Yadav, Arvind K. Dattatrey, Geeta Rangwal +3
We present the study of four FUV stars in the field of open cluster NGC 2420 using the Ultra Violet Imaging Telescope (UVIT) mounted on AstroSat. The three stars 525, 527, and 560…
UVIT/AstroSat Investigation of a low luminous Blue Straggler Star in NGC 362: Detection of extremely low mass white dwarf as companion
Arvind K. Dattatrey, R. K. S. Yadav, Annapurni Subramaniam +1
In the present study, we identified an extremely low-mass white dwarf as a companion to a low luminous blue straggler star within the Galactic globular cluster NGC 362. To conduct…
GlobULeS-V. UVIT/AstroSat studies of stellar populations in NGC 362: Detection of Blue Lurkers in a Globular Cluster
Arvind K. Dattatrey, R. K. S. Yadav, Gourav Kumawat +4
We report the discovery of four blue lurkers with low and extremely low-mass white dwarf (ELM WDs) companions in the Galactic globular cluster NGC 362 using AstroSat Ultra Violet I…
GlobULeS-IV. UVIT/AstroSat detection of extremely low mass white dwarf companions to blue straggler stars in NGC 362
Arvind K. Dattatrey, R. K. S. Yadav, Sharmila Rani +4
We report the discovery of extremely low-mass white dwarfs (ELM WDs) as a companion of blue straggler stars (BSSs) in the Galactic globular cluster NGC 362 using images from AstroS…
