The discovery of the ultraluminous X-ray pulsar M82 X-2 has stimulated lively discussion on the nature of the accreting neutron star. In most of the previous studies the magnetic field of the neutron star was derived from the observed spin-up/down rates based on the standard thin, magnetized accretion disk model. However, under super-Eddington accretion the inner part of the accretion disk becomes geometrically thick. In this work we consider both radiation feedback from the neutron star and… Expand

On the magnetic fields of ultraluminous X-ray pulsars
So far quite a few ultraluminous X-ray (ULX) pulsars have been discovered. In this work, we construct a super-Eddington, magnetic accretion disk model to estimate the dipole magnetic field of eightExpand

Possible manifestations of accreting magnetars are discussed. It is shown that the four ultra-luminous X-ray pulsars can be understood in the accreting low magnetic field magnetar scenario. TheExpand
On the Fallback Disk around the Slowest Isolated Pulsar, 1E 161348-5055
The central compact object 1E 161348$-$5055 in the supernova remnant RCW 103 has a spin period $\sim 6.67$ hr, making it the slowest isolated pulsar. It is believed that a supernova fallback disk isExpand

We report on analysis of observations of the bright transient X-ray pulsar Swift J0243.6+6124 obtained during its 2017-2018 giant outburst with Insight-HXMT, NuSTAR, and Swift observatories. WeExpand
A Population of Neutron Star Ultraluminous X-Ray Sources with a Helium Star Companion
It was recently proposed that a significant fraction of ultraluminous X-ray sources (ULXs) actually host a neutron star (NS) accretor. We have performed a systematic study on the NS ULX population inExpand
Unifying neutron star sub-populations in the supernova fallback accretion model
We employ the supernova fallback disk model to simulate the spin evolution of isolated young neutron stars (NSs). We consider the submergence of the NS magnetic fields during the supercriticalExpand
Do the Periodic Activities of Repeating Fast Radio Bursts Represent the Spins of Neutron Stars?
Fast radio bursts (FRBs) are mysterious radio transients with millisecond durations. Recently, ∼16 days of periodic activity and ∼159 days of possible periodicity were detected to arise from FRBExpand


Accretion mode of the ultraluminous X-ray source M82 X-2
Periodic pulsations have been found in emission from the ultra-luminous X-ray source (ULX) M82 X-2, strongly suggesting that the emitter is a rotating neutron star rather than a black hole. However,Expand
A Population of Ultraluminous X-ray Sources with An Accreting Neutron Star
Most ultraluminous X-ray sources (ULXs) are believed to be X-ray binary systems, but previous observational and theoretical studies tend to prefer a black hole rather than a neutron star accretor.Expand
Accretion by rotating magnetic neutron stars. III. Accretion torques and period changes in pulsating X-ray sources.
We use the solutions of the two-dimensional hydromagnetic equations obtained previously to calculate the torque on a magnetic neutron star accreting from a Keplerian disk. We find that the magneticExpand
Optically thick envelopes around ULXs powered by accreating neutron stars
Magnetized neutron stars power at least some ultraluminous X-ray sources. The accretion flow in these cases is interrupted at the magnetospheric radius and then reaches the surface of a neutron starExpand
Propeller effect in action in the ultraluminous accreting magnetar M82 X-2
We present here the first convincing observational manifestation of a magnetar-like magnetic field in an accreting neutron star in binary system - the first pulsating ultra-luminous X-ray source X-2Expand
On the Formation of Ultraluminous X-ray Sources with Neutron Star Accretors: the Case of M82 X-2
The recent discovery of a neutron star accretor in the ultra-luminous X-ray source M82 X-2 challenges our understanding of high-mass X-ray binary formation and evolution. By combining binaryExpand
Modelling the spin equilibrium of neutron stars in low‐mass X‐ray binaries without gravitational radiation
In this paper we discuss the spin equilibrium of accreting neutron stars in low-mass X-ray binaries (LMXBs). We demonstrate that, when combined with a naive spin-up torque, the observed data lead toExpand
