X-ray Activity of the RS CVn-type Star σ Gem with the First-Year Observations of Einstein Probe
Xuan Mao, Giuseppina Micela, Fabio Favata +3
Context. Stellar flares are energetic events driven by the sudden release of magnetic energy in the stellar atmosphere. Studying these flares is crucial for understanding their imp…
Probing burst-disc interaction and disc reflection in SAX J1808.43658 with NICER, XMM-Newton, and NuSTAR
Manoj Mandal, Sachindra Naik, Birendra Chhotaray
We performed a comprehensive study of thermonuclear bursts from the millisecond X-ray pulsar SAX J1808.43658 with XMM-Newton and NICER. We report the results from the analysis o…
Discovery of burst oscillations in the newly discovered millisecond X-ray pulsar SRGA J144459.2604207
Manoj Mandal, Sachindra Naik
Burst oscillations during thermonuclear X-ray bursts are powered by thermonuclear energy on the neutron star (NS) surface and typically occur close to the spin frequency of the NS.…
Photospheric radius expansion thermonuclear burst and X-ray reflection from the neutron star X-ray binary 4U 1702-429
Manoj Mandal, Sachindra Naik, Gaurava Kumar Jaisawal
We perform a comprehensive study of thermonuclear bursts from the neutron star low-mass X-ray binary 4U 1702-429 detected with NICER and XMM-Newton. The thermonuclear burst detecte…
