- Vela Pulsar
The Vela Pulsar (PSR B0833-45 or PSR J0835-4510) is a radio, optical, X-ray and gamma-emitting
pulsar associated withVela Supernova Remnant , in theconstellation ofVela . The association of the Vela pulsar with theVela Supernova Remnant , made by astronomers at theUniversity of Sydney in1968 , [http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1968Natur.220..340L] was direct observational proof thatsupernovae formneutron stars .It has a period of 89 ms (the shortest known at the time of its discovery) and the remnant from the supernova explosion is estimated to be travelling at 1,200 km/s. [cite book |last= Lyne |first= Andrew G. |coauthors= Francis Graham-Smith |title= Pulsar Astronomy |publisher= Cambridge University Press |year= 1998 |isbn= 0-521-59413-8 ] It has the third brightest optical component of all known pulsars (magnitude 23.6) [cite journal |journal= Astronomy & Astrophysics |year=2007-10-01 |author= Mignani et al |title= The optical spectrum of the Vela Pulsar] which pulses twice for every single radio pulse. The Vela pulsar is the brightest persistent object in the high energy gamma ray sky.
