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…
Instability in supernova fallback disks and its effect on the formation of ultra long period pulsars
Hao-Ran Yang, Xiang-Dong Li, Shi-Jie Gao +1
Several pulsars with unusually long periods were discovered recently, comprising a potential population of ultra long period pulsars (ULPPs). The origin of their long periodicity i…
The influence of the magnetic braking laws on the evolution of persistent and transient low-mass X-ray binaries
Hao-Ran Yang, Xiang-Dong Li
Swift J1858.60814 (hereafter J1858) is a transient neutron star low-mass X-ray binary (NS LMXB). There is controversy regarding its donor mass derived from observations and theo…
On the Interacting/Active Lifetime of Supernova Fallback Disk around Isolated Neutron Stars
Kun Xu, Hao-Ran Yang, Long Jiang +3
The fallback disk model is widely accepted to explain long-period neutron stars (NSs) which can't be simulated by magnetic dipole radiation. However, no confirmed detection of disk…
