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…

X-Ray spectral and temporal properties of LMXB 4U 1608-52- observed with AstroSat and NICER

Sree Bhattacherjee, Ankur Nath, Biplob Sarkar +4

We report results from a detailed study of the neutron star X-ray binary, 4U 1608-52 using observations with {\it AstroSat} (LAXPC/SXT) and {\it NICER} during its 2016 and 2020 out…
