A Unique Star

The astronomers were made confused by the discovery of a pulsar with an abnormal orbit that had never been seen before, in similar neutron stars proceeding fast and broadcast a radio waves vibration in an orderly fashion.

Pulsar usually has a round orbit around the young white stars, but this space object that was found moved in oval or "eccentric" tracks around the stars.

The pulsar, that was called J1903+0327, the distance 20.000 lightyear from Earth and had a mass around 1.74 sun times, that make the pulsar heavier than usually.

The pulsar had the speed 2.15 millisecond rotation period or 465 cycle per second, so the object as the 5th proceeding fastest pulsar that was known in our galaxy.

The international astronomer team felt was sure this pulsar was born in the densely populated star region that was known as the round group, before being thrown out by the star that had been circled by it.

The other theory stated that pulsar might be consisting of two stars. The pulsar possibly a system of three first stars, while approximately 100 pulsars were part of two stars team .

The team identified the pulsar as most likely being associated with the remnant of a supernova that exploded in the Large Magellanic Cloud, a companion to our Milky Way galaxy, about 4,000 years ago. Nevertheless, often the phenomenon created a black hole or vanished without a trace.

The first pulsar was observed in July 1968 by an English physicist Antony Hewish, and his pupils, Jocelyn Bell Burnell.
