OverviewAI-generated summary
Sayantan Bhattacharya's research interests lie in astrophysics and computational modeling, with a focus on celestial objects and phenomena. His work includes modeling the luminosity-dependent pulse profile and emission geometry of X-ray binaries such as SMC X-2 during outbursts. He also investigates the magnetic dipole moment and magnetospheric fluctuations of objects like SXP 18.3 using Kalman filters and examines stellar winds of Wolf–Rayet stars, such as the one in IC 10 X-1. Bhattacharya has contributed to the study of self-lensing phenomena, including revisiting KIC 12254688 and analyzing Chandra observations of a potential supermassive black hole binary system, Spikey. His research also extends to modeling long-term variability in stellar-compact object binary systems for mass determination. Bhattacharya has published 56 papers, with an h-index of 5 and 85 citations.
