Pulse profile modelling of accreting millisecond pulsars with disc occultation and its impact on parameter inference
Ying-Han Mao, Bas Dorsman, Anna L. Watts +3
Pulse profile modelling is a relativistic ray-tracing technique used to infer neutron star mass, radius, and surface hotspot properties from X-ray pulsations. Pulse profile modelli…
Pulse profile modelling of the 2024 outburst of the accreting millisecond pulsar SRGA J144459.2-604207
Bas Dorsman, Tuomo Salmi, Anna L. Watts +14
Pulse profile modelling via relativistic ray-tracing can constrain the system parameters of neutron stars, notably their mass and radius. Among these objects, accreting millisecond…
How Beaming Shapes the Demographics of Ultraluminous X-ray Sources?
Ying-Han Mao, Xiang-Dong Li
Ultraluminous X-ray sources (ULXs) are off-nuclear compact objects with apparent luminosities above 10^39 erg/s, often exceeding the Eddington limit for stellar-mass black holes. B…
Formation of millisecond pulsar-helium star binaries
Zhu-Ling Deng, Xiang-Dong Li, Yong Shao +2
PSR J1928+1815, the first recycled pulsar-helium (He) star binary discovered by the Five-hundred-meter Aperture Spherical radio Telescope, consists of a 10.55 ms pulsar and a compa…
A statistical study of type II outbursts of XRPs: Brighter accreting pulsars rotate faster
Shan-Shan Weng, Xiao-Tian Xu, Han-Long Peng +6
X-ray pulsars (XRPs) consist of a magnetized neutron star (NS) and an optical donor star. The NS accretes matter from the donor star producing pulsed X-ray emission. In most cases…
A binary origin of ultra-long period radio pulsars
Ying-Han Mao, Xiang-Dong Li, Dong Lai +2
We propose a possible binary evolution model for the formation of ultra-long period pulsars (ULPPs). The model involves two key stages: first, a neutron star (NS) in wide binaries…
