Revised Pulsar Spin‐down

A Study of the Gravitational Wave Pulsar Signal with Orbital and Spindown Effects

In this work we present analytic and numerical treatments of the gravitational wave signal from a pulsar which includes spindown. We consider phase corrections to a received monochromatic signal due to rotational and elliptical orbital motion of the Earth, as well as perturbations due to Jupiter and the Moon. We discuss the Fourier transform of such a signal, which is expressed in terms of well...

Constraints on Pulsar Evolution: The Joint Period-Spindown Distribution of Millisecond Pulsars

We calculate the joint period-spindown (P − Ṗ ) distributions of millisecond radio pulsars (MSRP) for the standard evolutionary model in order to test whether the observed MSRPs are the unequivocal descendants of millisecond X-ray pulsars (MSXP). The P − Ṗ densities implied by the standard evolutionary model compared with observations suggest that there is a statistically significant overabunda...

A ug 1 99 7 Implications of a constant observed braking index for young pulsar ’ s spindown

The observed braking index n obs which had been determined for a few young pulsars, had been found to differ from the expected value for a rotating magnetic dipole model. In addition, the observational jerk parameter, determined for two of these pulsars, disagrees with the theoretical prediction m obs = 15 in both cases. We propose a simple model able to account for these differences, based on ...

Quantum vacuum influence on pulsars spindown evolution

Disk-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 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 n < 3 for...
