题目：Ultraluminous X-ray pulsar: accreting magnetar?
摘要：Abstract One ultraluminous X-ray source in M82 is identified as an accreting neutron
star recently (named as NuSTAR J095551+6940.8). It has a super-Eddington luminosity
and is spinning up. For an aged magnetar, it is more likely to be a low magnetic field
magnetar. An accreting low magnetic field magnetar may explain both the super-Eddington
luminosity and the rotational behavior of this source. Considering the effect of beaming,
the spin-up rate is understandable using the traditional form of accretion torque. The
transient nature, spectral properties of M82 X-2 are discussed. The theoretical period
range ofaccreting magnetar is provided. Three observational appearances of accreting
