Magnetar Spin-Down.
We examine the effects of a relativistic wind on the spin-down of a neutron star and apply our results to the study of soft gamma repeaters (SGRs), which are thought to be neutron stars with magnetic fields greater than 1014 G. We derive a spin-down formula that includes torques from both dipole radiation and episodic or continuous particle winds. We find that if SGR 1806-20 puts out a continuo...
متن کاملBeating the Spin-down Limit on Gravitational Wave Emission from the Vela Pulsar
We present direct upper limits on continuous gravitational wave emission from the Vela pulsar using data from the Virgo detector’s second science run. These upper limits have been obtained using three independent methods that assume the gravitational wave emission follows the radio timing. Two of the methods produce frequentist upper limits for an assumed known orientation of the star’s spin ax...
متن کاملShort Duration Gamma-Ray Bursts with Extended Emission from Proto-Magnetar Spin-Down
Evidence is growing for a class of gamma-ray bursts (GRBs) characterized by an initial ∼ 0.1 − 1 s spike of hard radiation followed, after a ∼ 3 − 10 s lull in emission, by a softer period of extended emission lasting ∼ 10 − 100 s. In a few well-studied cases, these “short GRBs with extended emission” show no evidence for a bright associated supernova (SN). We propose that these events are prod...
متن کاملFormation of Millisecond Pulsars from Accretion Induced Collapse and Constraints on Pulsar Gamma Ray Burst Models
We study accretion induced collapse of magnetized white dwarfs as an origin of millisecond pulsars. We apply magnetized accretion disk models to the pre-collapse accreting magnetic white dwarfs and calculate the white dwarf spin evolution. If the pulsar magnetic field results solely from the flux-frozen fossil white dwarf field, a typical millisecond pulsar is born with a field strength ∼ 10 − ...
متن کاملIsolated Magnetar Spin-down, Soft X-ray Emission and Rxj1856.5-3754
When an isolated magnetar with magnetic dipole field B ∼ 10 G moves at high velocity (v > 10 cm s) through the ISM, its transition into propeller effect driven spin-down may occur in less than 10 years. We propose that the nearby neutron star RXJ1856.5-3754 is such a magnetar, and has spun down by the propeller effect to a period greater than 10 sec within ∼ 5 × 10 years. This magnetar scenario...
