In the summer of 2012, during a Pulsar Search Collaboratory workshop, two high-school students discovered J1930–1852, a pulsar in a double neutron star (DNS) system. Most DNS systems are characterized by short orbital periods, rapid spin periods, and eccentric orbits. However, J1930–1852 has the longest spin period ( P spin ∼ ?> 185 ms) and orbital period ( P b ∼ ?> 45 days) yet measured among known, recycled pulsars in DNS systems, implying a shorter than average and/or inefficient recycling…
