Though pulsars spin regularly, the differences between the observed and predicted ToA (time of arrival), known as "timing noise", can still reach a few milliseconds or more. We try to understand the noise in this study. As proposed by Xu and Qiao in 2001, both dipole radiation and particle emission would result in pulsar braking. Accordingly, possible fluctuation of particle current flow is suggested here to contribute significant ToA variation of pulsars. We find that the particle emission…

Pulsar braking: magnetodipole vs. wind
Pulsars are good clocks in the universe. One fundamental question is that why they are good clocks? This is related to the braking mechanism of pulsars. Nowadays pulsar timing is done with
Recent glitches detected in the Crab pulsar
From 2000 to 2010, monitoring of radio emission from the Crab pulsar at Xinjiang Observatory detected a total of nine glitches. The occurrence of glitches appears to be a random process as described
Fluctuating neutron star magnetosphere: braking indices of eight pulsars, frequency second derivatives of 222 pulsars and 15 magnetars
Eight pulsars have low braking indices, which challenge the magnetic dipole braking of pulsars. 222 pulsars and 15 magnetars have abnormal distribution of frequency second derivatives, which also

We model the evolution of the spin frequency's second derivative $\ddot\nu$ and the braking index $n$ of radio pulsars with simulations within the phenomenological model of their surface magnetic
Testing Models of Magnetic Field Evolution of Neutron Stars with the Statistical Properties of their Spin Evolutions
We test models for the evolution of neutron star (NS) magnetic fields (B). Our model for the evolution of the NS spin is taken from an analysis of pulsar timing noise presented by Hobbs et al.. We

A novel high-speed tensile facility (HSTF) with special fixture is applied to research the dynamic failure characteristics of oxygen-free high-conductivity (OFHC) copper bars at different levels of


We investigate rotational spin noise (referred to as timing noise) in non-accreting pulsars: millisecond pulsars, canonical pulsars, and magnetars. Particular attention is placed on quantifying the
JPL pulsar timing observations. III. Pulsar rotation fluctuations.
Pulsar arrival-time data from a timing program carried out at the Jet Propulsion Laboratory from 1968 to 1982 at 2390 MHz were analyzed to study the precision of neutron star rotation rates. Most of
A Statistical Analysis of Radio Pulsar Timing Noise
We present an analysis of the timing observations on 27 radio pulsars, collected at Hartebeesthoek Radio Astronomy Observatory (HartRAO), with time spans ranging between ~ 9 and 14 yr. Our results
Detecting the Stochastic Gravitational Wave Background Using Pulsar Timing
The direct detection of gravitational waves is a major goal of current astrophysics. We provide details of a new method for detecting a stochastic background of gravitational waves using pulsar
An analysis of the timing irregularities for 366 pulsars
We provide an analysis of timing irregularities observed for 366 pulsars. Observations were obtained using the 76-m Lovell radio telescope at the Jodrell Bank Observatory over the past 36 years.
Pulsar Timing Noise
Pulsar timing techniques allow a pulsar's rotational, astrometric and binary parameters to be measured to high precision. Any features that remain in the timing residuals after fitting for the
Evidence for free precession in a pulsar
The discovery of long-term, highly periodic and correlated variations in both the pulse shape and the rate of slow-down of the pulsar PSR B1828-11, probably resulting from precession of the spin axis caused by an asymmetry in the shape ofThe pulsar.
Switched Magnetospheric Regulation of Pulsar Spin-Down
It is shown that the rotation of pulsars is not modulated by a single spin-down rate but typically by two, each accompanied by a unique pulse profile, and that for six pulsars the timing noise is correlated with changes in the pulse shape.
