Pulsar J1411+2551: A Low Mass New Double Neutron Star System

Understand

In this work, we report the discovery and characterization of PSR J1411+2551, a new binary pulsar discovered in the Arecibo 327 MHz Drift Pulsar Survey.

• Our timing observations of the radio pulsar in the system span a period of about 2.5 years.
• This timing campaign allowed a precise measurement of its spin period (62.4 ms) and its derivative (9.6 $\pm$ 0.7) $\times 10^{-20}\, \rm s\, s^{-1}$; from these, we derive a characteristic age of $\sim 10\,$Gyr and a surface magnetic field strength of 2.5 $\times 10^{9}$ G.
• These numbers indicate that this pulsar was mildly recycled by accretion of matter from the progenitor of the companion star.
