Planets in Pulsar Winds
T. Kaister, S. Andrés Joya Méndez, P. Marmat +4
Planets around pulsars were the first discovered exoplanets, found thanks to the extremely precise pulsar timing. Here we suggest that they could also be found through the radio em…
Probing the accreting millisecond X-ray pulsar SAX J1808.4-3658 using the evolution of its spectral and aperiodic timing properties
Aman Kaushik, Yash Bhargava, Sudip Bhattacharyya +1
Understanding accretion components in neutron star (NS) low mass X-ray binary (LMXB) systems is important to probe fundamental aspects of accretion mechanism and evolution of the s…
Timing and spectral studies of SRGA J144459.2604207 with NICER, Einstein Probe, IXPE, NuSTAR, Insight-HXMT and INTEGRAL during its 2024 outburst
Zhaosheng Li, Lucien Kuiper, Yuanyue Pan +13
SRGA J144459.2604207 is a newly confirmed accreting millisecond X-ray pulsar and type I X-ray burster. We present the broadband X-ray timing and spectral behaviors of SRGA J1444…
Observatory Science with eXTP
Ping Zhou, Jirong Mao, Liang Zhang +97
Scheduled for launch in 2030, the enhanced X-ray Timing and Polarization (eXTP) telescope is a Chinese space-based mission aimed at studying extreme conditions and phenomena in ast…
Emission and Absorption Lines in Photospheric Radius Expansion Bursts of 4U 182030
Wenhui Yu, Zhaosheng Li, Yuanyue Pan +4
We analyze the emission and absorption lines during photospheric radius expansion (PRE) X-ray bursts from the ultracompact binary 4U 1820--30, observed with the Neutron Star Interi…
Quenching and recovery of persistent X-ray emission during a superburst in 4U 182030
Zhijiao Peng, Zhaosheng Li, Yuanyue Pan +6
We report the superburst from 4U 1820--30 in 2021 observed by the Monitor of All-sky X-ray Image and Neutron star Interior Composition Explorer (NICER). During the tail of the supe…
