Discovery of Eight Recycled Pulsars - The Swinburne Intermediate Latitude Pulsar Survey

TL;DR

This paper reports a successful pulsar survey at intermediate Galactic latitudes, discovering 58 new pulsars, including eight recycled ones, providing insights into white dwarf pulsar binary formation and characteristics.

Contribution

The survey's rapid discovery of 58 pulsars, especially eight recycled systems, offers new data on binary evolution and white dwarf companions in pulsar systems.

Findings

Discovered 58 new pulsars in 14 days

Identified 8 recycled pulsars with binary companions

Found systems with massive and low-mass white dwarf companions

Abstract

We have conducted a pulsar survey of intermediate Galactic latitudes (15deg < |b| < 5deg) at 20 cm. The survey has been highly successful, discovering 58 new pulsars, eight of which are recycled, in only ~14 days of integration time. One pulsar has a very narrow (2deg FWHM) average profile for the pulsar's period (278 ms). The six new recycled binary systems provide valuable information on the formation of white dwarf pulsar binaries. Two systems have massive white dwarf companions (> 0.57 Mo and > 1.2 Mo), while anotherhas a low mass (~0.2 Mo) companion in a 23.3-d orbit, residing the well-known orbital period ``gap''.
