Discovered the most rapidly rotating superdense star

Scientists have found evidence of what may be the fastest moving pulsar. During the observation using three different telescopes - NASA's X-ray Observatory "Chandra", ESA XMM-Newton, located in space, and a radio telescope Parks in Australia.

X-ray observations, "Chandra" and XMM-Newton were combined with infrared data of the project 2MASS optical data and digital images of the sky.

During the observation was reported explosion of a massive star that turned into a supernova (MSH 11-16A), leaving behind a vast field of debris. The explosion of a rapidly rotating superdense star (known as "pulsar") was ejected in the explosion and is now racing away from the supernova remnant at the rate of millions of miles per hour.

Based on earlier observations, astronomers believe that the age of MSH 11-61A is about 15,000 years old and is located about 30,000 light-years from Earth. According to these data and the distance of the pulsar from its original location, astronomers calculated that its speed is between 5.4 to 6.5 million km / h .

The only other neutron star associated with the remnant of a supernova that can compete with this speed, is the candidate who is in the supernova remnant known as G350.1-0.3. The rate of the neutron star is about 6.3 million km / h.

If these data are confirmed, then, according to scientists, such a high rate of neutron stars is a serious threat to the existing model of a supernova explosion.
