Pulsar glitch substructure and pulsar interiors

TL;DR

This study analyzes 24 years of pulsar timing data from Vela, revealing that its spin-up occurs instantaneously and discussing how higher resolution data could further illuminate neutron star interiors.

Contribution

It provides long-term, high-resolution timing observations of Vela, confirming the instantaneous nature of its spin-up and exploring implications for neutron star interior models.

Findings

Vela's spin-up is instantaneous within data uncertainties

Extended timing data reveals detailed pulsar behavior

Potential for higher resolution data to uncover neutron star interior insights

Abstract

Pulsar timing at the Mt Pleasant observatory focused on Vela, which could be tracked for 18 hours of the day. These nearly continuous timing records extend over 24 years allowing a great insight into details of timing noise, micro glitches and other more exotic effects. It has been found that the spin up for the Vela pulsar occurs instantaneously to within the uncertainties of the data. The potential for new, higher resolution data, to unveil insights of the Neutron Star interiors is discussed.
