From One to Two: A Second Binary Millisecond Pulsar in the Globular Cluster M92 (NGC 6341)
Dejiang Yin, Li-yun Zhang, Baoda Li +4
We report the discovery and phase connected-timing solution of a second millisecond binary pulsar, PSR J1717+4308B (M92B), in the globular cluster M92 (NGC 6341) using the Five-hun…
