PSR J1719−1438
Millisecond pulsar in the constellation Serpens / From Wikipedia, the free encyclopedia
PSR J1719-1438 is a millisecond pulsar with a spin period of 5.8 ms located about 4,000 ly from Earth in the direction of Serpens Cauda,[1][2] one minute from the border with Ophiuchus. Millisecond pulsars are generally thought to begin as normal pulsars and then spin up by accreting matter from a binary companion.
