Rotation of Neutron Star Influences Rate of Thermonuclear Explosions at Surface

(Best Syndication News) Scientists have been studying neutron stars for decades and believe they have discovered one that could change the way they view their behavior.
Neutron stars are typically small, perhaps just 10 miles in width, but contain up to two solar masses. They are created when a massive star collapses after a supernova event. Several years ago scientists spotted eruptions on IGR J17480–2446, a neutron star near our galaxy’s center. They dubbed the neutron star, which is orbiting a star about the size of our sun, T5X2.
In 2010 astronomers noticed hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the neutron star's surface. T5X2, which lies about 25,000 light years from earth, began to emit regular pulses like a pulsar.
Through accretion, matter is being transferred from the star to the neutron star. Explosions occur as the matter makes contact with the neutron star.
