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…

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…
