چکیده
It is found that 1E 1207.4-5209 could be a low-mass bare strange star if its smaller radius or low altitude cyclotron formation can be identified. The age problems of five sources could be solved by a fossil-disk-assisted torque. The magnetic dipole radiation dominates the evolution of PSR B1757-24 at present, and the others are in propeller (or tracking) phases.

متن کاملAccretion torque on magnetized neutron stars
The conventional picture of disk accretion onto magnetized neutron stars has been challenged by the spin changes observed in a few X-ray pulsars, and by theoretical results from numerical simulations of diskmagnetized star interactions. These indicate possible accretion during the propeller regime and the spin-down torque increasing with the accretion rate. Here we present a model for the accre...
متن کاملConstraints on the Steady-state R-mode Amplitude in Neutron Star Transients
Recent observations suggest that neutron stars in low-mass X-ray binaries rotate within a narrow range of spin frequencies clustered around 300Hz. A proposed explanation for this remarkable fact is that gravitational radiation from a steady-state r-mode oscillation in the neutron star’s core halts the spin-up due to accretion. For the neutron star transients, balancing the time-averaged accreti...
متن کاملAccretion onto Fast X-ray Pulsars
The recent emergence of a new class of accretion-powered, transient, millisecond X-ray pulsars presents some difficulties for the conventional picture of accretion onto rapidly rotating magnetized neutron stars and their spin behavior during outbursts. In particular, it is unclear from the standard paradigm how these systems manage to accrete over such a wide range in Ṁ (i.e., & a factor of 50)...
متن کاملAccretion-Assisted Spindown of Young Radio Pulsars
We present a model for the spindown of young radio pulsars in which the neutron star loses rotational energy not only by emitting magnetic dipole radiation but also by torquing a surrounding accretion disk produced by supernova fallback. The braking index predicted in our model is in general less than n = 3 (the value for pure dipole magnetic radiation), in agreement with the reported values of...
