A low mass and radius neutron star candidate in XTE J1810-189?
Shoutao Ban, Helei Liu, Zhaosheng Li +7
Photosphere radius expansion (PRE) bursts provide a crucial tool for constraining the mass and radius of neutron stars. In this study, we analyze time-resolved spectroscopic data f…
X-ray and radio observations of the AMXP MAXI J1957+032 covering the 2022-2025 outbursts
Zhaosheng Li, Lucien Kuiper, Yuanyue Pan +12
We presented a comprehensive multi-epoch timing and multiwavelength analysis of the accreting millisecond X-ray pulsar MAXI J1957+032, covering two major outbursts in 2022 and 2025…
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…
A comprehensive study of type I (thermonuclear) bursts in the new transient SRGA J144459.2604207
Tao Fu, Zhaosheng Li, Yuanyue Pan +11
We report an analysis of Insight-HXMT observations of the newly discovered accreting millisecond pulsar SRGA J144459.2604207. During the outburst, detected in 2024 February by S…
