The GMRT High-resolution Southern Sky Survey for Pulsars and Transients. VII. Timing of the Spider Millisecond Pulsar PSR J1242–4712, a Bridge between Redback and Black Widow Pulsars

The Astrophysical Journal
We present a timing solution for the 5.31 ms spider millisecond pulsar (MSP) J1242−4712, discovered with the GMRT. PSR J1242−4712 orbits a companion of minimum mass 0.08 M _⊙ with an orbital period of 7.7 hr and occupies a relatively unexplored region in

Identifying Pulsar Candidates in Interferometric Radio Images Using Scintillation

The Astrophysical Journal
Pulsars have been primarily detected by their narrow pulses or periodicity in time domain data. Interferometric surveys for pulsars are challenging due to the trade-off between beam sensitivity and beam size and the corresponding tradeoff between survey ...

A Binary Origin for Ultralong-period Radio Pulsars

The Astrophysical Journal Letters
We propose a possible binary evolution model for the formation of ultralong-period pulsars. The model involves two key stages: first, a neutron star (NS) in wide binaries undergoes an effective spin-down phase through wind-fed accretion from its massive ...
