Abstract: The low braking-index pulsar PSR J1734$-$3333 could be born with superhigh internal magnetic fields $B_{\rm in}\sim10^{15}-10^{16}$ G, and undergo a supercritical accretion soon after its formation in a supernova explosion. The buried multipole magnetic fields… read more here.

DOI: 10.1016/j.actaastro.2019.10.016
Abstract: Abstract Existing methods for simulating pulsar signals at a spacecraft are inapplicable for large flux or high frequency because of their low efficiency, hindering research on X-ray pulsar-based navigation. To solve the problem, we propose… read more here.

DOI: 10.1038/s41550-017-0266-2
Abstract: Millisecond pulsars are neutron stars that attain their very fast rotation during a 108–109-yr-long phase of disk accretion of matter from a low-mass companion star1,2. They can be detected as accretion-powered millisecond X-ray pulsars if… read more here.
