Spectral-timing analysis of the kilohertz quasi-periodic oscillations and constraints on the mass of the neutron star in 4U 1636-536 using AstroSat observations
Suchismito Chattopadhyay, Soma Mandal, Ranjeev Misra
Kilohertz quasi-periodic oscillations (kHz QPOs) are believed to originate from the orbital timescales of the inner accretion flow, reflecting the dynamics of the innermost disk re…

QPO signatures of disk restoration after type-I X-ray bursts from 4U~1636536
Suchismito Chattopadhyay, Jaiverdhan Chauhan, Ranjeev Misra +4
Type--I thermonuclear bursts (TNBs) from neutron star low-mass X-ray binaries (NS LMXBs) originate on the neutron star's surface from the unstable burning of the accreted material.…

Spectro-temporal evolution of 4U 1702-429 using AstroSat-NICER
Suchismito Chattopadhyay, Ranjeev Misra, Soma Mandal +2
We present the broadband spectral and timing properties of the atoll source 4U 1702-429 using two observations of AstroSat with the second one having simultaneous NICER data. For b…
