Arecibo Pulsar Survey Using ALFA. II. The Young, Highly Relativistic Binary Pulsar J1906+0746
We report the discovery of PSR J1906+0746, a young 144-ms pulsar in a highly relativistic 3.98-hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of ∼ 300 Myr.The new pulsar was found during precursor survey observations with the Arecibo 1.4-GHz feed array system and retrospectively detected …
