Microscopic magnetic dipole radiation in neutron stars
نویسندگان
چکیده
There is P2 neutron superfluid region in NS (neutron star) interior. For a rotating NS, the P2 superfluid region is like a system of rotating magnetic dipoles. It will give out electromagnetic radiation, which may provides a new heating mechanism of NSs. This heating mechanism plus some cooling agent may give sound explanation to NS glitches.

Gravitational waves from inspiralling compact binaries with magnetic dipole moments
We investigate the effects of the magnetic dipole-dipole coupling and the electromagnetic radiation on the frequency evolution of gravitational waves from inspiralling binary neutron stars with magnetic dipole moments. This study is motivated by the discovery of the superstrongly magnetized neutron stars, i.e., magnetar. We derive the contributions of the magnetic fields to the accumulated cycl...
متن کاملThe Disk-Magnetosphere Interaction in the Accretion-Powered Millisecond Pulsar SAXJ1808.4–3658
The recent discovery of the first known accretion-powered millisecond pulsar with the Rossi X-Ray Timing Explorer allows the first direct test of models for the interaction of the accretion disk and the magnetic field of weakly magnetic (B ∼< 10 10 G) neutron stars in X-ray binaries. The simple Ṁ3/7 scaling law for the Keplerian frequency at the magnetic interaction radius, widely used to model...
متن کاملDifferent Magnetic Field Distributions in Deformed Neutron Stars
In this work, we review the formalism which would allow us to model magnetically deformed neutron stars. We study the effect of different magnetic field configurations on the equation of state (EoS) and the structure of such stars. For this aim, the EoS of magnetars is acquired by using the lowest order constraint variational (LOCV) method and employing the AV18 potential....
متن کاملSoft Gamma Ray Repeaters and Anomalous X-Ray Pulsars: Magnetars or Young Quark Stars?
Recent measurements of the spin-down rates of soft gamma ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) have been interpreted as evidence that these objects are “magnetars”: neutron stars spinning down by magnetic dipole radiation, but with a magnetic field two orders of magnitude larger than that of ordinary neutron stars. We discuss the evidence disfavouring this interpretation. We a...
متن کاملR-Mode Oscillations and Spindown of Young Rotating Magnetic Neutron Stars
Recent work has shown that a young, rapidly rotating neutron star loses angular momentum to gravitational waves generated by unstable r-mode oscillations. We study the spin evolution of a young, magnetic neutron star including both the effects of gravitational radiation and magnetic braking (modeled as magnetic dipole radiation). Our phenomenological description of nonlinear r-modes is similar ...
