Revisiting the Evidence for Double Sequences of Blue Straggler Stars in Globular Clusters
Gourav Kumawat, Craig O. Heinke, Alison Sills +5
Blue straggler stars (BSSs) are believed to form through mass transfer in binary systems or stellar collisions. The reported presence of double BSS sequences in some globular clust…
A Comprehensive Analysis of X-ray Sources in Terzan 5 Using Chandra Observations
Gourav Kumawat, Craig O. Heinke, Jiaqi Zhao +3
We analyze photometry, spectra, and variability of over 100 faint X-ray sources in the globular cluster Terzan 5, using 737 ks of Chandra data. X-ray colors and spectral fitting al…
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…
Searching for exotic object companions in the dense core of NGC 362: a multi-wavelength and multi-epoch photometric analysis
Greta Ettorre, Emanuele Dalessandro, Cristina Pallanca +8
The dense cores of globular clusters (GCs) are efficient environments for the production of exotic stellar populations, including millisecond pulsars (MSPs), low-mass X-ray binarie…
Chandra and HST studies of the X-ray sources in the Globular Cluster NGC 362
Gourav Kumawat, Craig O. Heinke, Haldan N. Cohn +1
We analyse a Chandra observation of the rich globular cluster NGC 362, finding 33 X-ray sources within 1' (1.2 half-mass radii) of the cluster center. Spectral analysis of the brig…
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…
