Spin Down of Rotating Compact Magnetized Strange Stars in General Relativity

TL;DR

This paper investigates how the rotation of magnetized strange stars slows down faster than neutron stars in general relativity, suggesting pulsar spindown data could help identify strange stars.

Contribution

It demonstrates that strange stars experience a more rapid rotational slowdown due to magnetodipolar radiation compared to neutron stars of the same mass.

Findings

Strange stars spin down faster than neutron stars in general relativity.

Pulsar spindown data can potentially distinguish strange stars from neutron stars.

Abstract

We find that in general relativity slow down of the pulsar rotation due to the magnetodipolar radiation is more faster for the strange star with comparison to that for the neutron star of the same mass. Comparison with astrophysical observations on pulsars spindown data may provide an evidence for the strange star existence and, thus, serve as a test for distinguishing it from the neutron star.
