PROPERTIES AND EVOLUTION OF THE REDBACK MILLISECOND PULSAR BINARY PSR J2129–0429 [PDF]
, 2015 PSR J2129−0429 is a “redback” eclipsing millisecond pulsar binary with an unusually long 15.2 hr orbit. It was discovered by the Green Bank Telescope in a targeted search of unidentified Fermi gamma-ray sources.

Apparently Ultralong Period Radio Signals from Self-lensed Pulsar–Black Hole Binaries
The Astrophysical JournalPulsar–black hole (BH) close binary systems, which have not been found yet, are unique laboratories for testing theories of gravity and understanding the formation channels of gravitational-wave sources.

PSR J2150+3427: A Possible Double Neutron Star System
The Astrophysical Journal Letters, 2023 PSR J2150+3427 is a 0.654 s pulsar discovered by the Commensal Radio Astronomy FAST Survey. From the follow-up observations, we find that the pulsar is in a highly eccentric orbit ( e = 0.601) with an orbital period of 10.592 days and a projected ...

A formation scenario for the triple pulsar PSR J0337+1715: breaking a binary system inside a common envelope [PDF]
, 2015 We propose a scenario for the formation of the pulsar with two white dwarfs (WDs) triple system PSR J0337+1715. In our scenario a close binary system is tidally and frictionally destroyed inside the envelope of a massive star that later goes through an ...

Inferring the composition of super-Jupiter mass companions of pulsars with radio line spectroscopy
, 2017 We propose using radio line spectroscopy to detect molecular absorption lines (such as OH at 1.6-1.7 GHz) before and after the total eclipse of black widow (BW) and other short orbital period binary pulsars with low mass companions. The companion in such

KECK SPECTROSCOPY OF MILLISECOND PULSAR J2215+5135: A MODERATE- MNS, HIGH-INCLINATION BINARY [PDF]
, 2015 We present Keck spectroscopic measurements of the millisecond pulsar binary J2215+5135. These data indicate a neutron-star (NS) mass M NS = 1.6 M ⊙ ?> , much less than previously estimated.

New Direct Observational Evidence for Kicks in SNe [PDF]
, 2000 We present an updated list of direct strong evidence in favour of kicks being imparted to newborn neutron stars. In particular we discuss the new cases of evidence resulting from recent observations of the X-ray binary Circinus X-1 and the newly ...
