Spectroscopic Study of Blue Straggler Stars in the Globular Cluster NGC 3201 Open
We conducted a spectroscopic study of 39 blue straggler stars in the globular cluster NGC~3201. The spectra of these stars have been previously reported. We determined the radial velocity, atmospheric parameters (T$_{eff}$, log $g$), Mg ab…

A Comprehensive Analysis of X-Ray Sources in Terzan 5 Using Chandra Observations Open
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 allow for clear separation of foreground sources (with less e…

Searching for exotic object companions in the dense core of NGC 362 Open
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 binaries (LMXBs), and cataclysmic variables (CVs). Most of these o…

<i>Chandra</i> and <i>HST</i> studies of the X-ray sources in the globular cluster NGC 362 Open
We analyse a Chandra observation of the rich globular cluster NGC 362, finding 33 X-ray sources within 1 arcmin (1.2 half-mass radii) of the cluster centre. Spectral analysis of the brightest source (X1) shows blackbody-like emission, indi…

GlobULeS-V. UVIT/AstroSat studies of stellar populations in NGC 362: Detection of Blue Lurkers in a Globular Cluster Open
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 Imaging Telescope (UVIT). We analyzed the multi-wavelength s…
