22 Pulsars Found in The Star Cluster in Our Galaxy

As reported by New Scientist, American astronomers, used the hundred-meter radio telescope in Green Bank, West Virginia, were able to detect 21 previously unknown pulsars. Pulsars are hidden in a cluster of ancient (not to say the oldest) stars in globular clusters Terzan five near the center of our galaxy. Earlier in this cluster have been three known pulsar. This is so far the absolute record of any known star cluster. The previous record holder – 47 Tucanae (47 Tucanae) contains only 22 of the pulsar.

As reported by New Scientist, American astronomers, used the hundred-meter radio telescope in Green Bank, West Virginia, were able to detect 21 previously unknown pulsars. Pulsars are hidden in a cluster of ancient (not to say the oldest) stars in globular clusters Terzan 5 near the center of our galaxy. Earlier in this cluster have been three known pulsar. This is so far the absolute record of any known star cluster. The previous record holder – 47 Tucanae (47 Tucanae) contains only 22 of the pulsar.

It is believed that a pulsar – the remnants of ordinary stars, extremely dense blob of matter that remains after the collapse of stars, the rapidly rotating and emitting a flood of radio waves. Due to rotation of the pulsar and its emission recorded on Earth in the form of cyclic pulses.

The average age of “living” stars in the cluster Terzan 5 is 10 billion years (ie, they average only 3-4 billion years younger than the Big Bang).

All newly discovered pulsars spin hundreds of times faster than most of the 1,500 currently known pulsars. The fastest of these rotates with a period of 600 times per second. Astronomers speculate that these pulsars are rotating so fast because of the fact that at some point they draw closer to other stars to give them additional angular acceleration. In the globular cluster Terzan 5 Pulsars are rapidly rotating in such abundance is due to the fact that the stars are there extremely tight up to 10,000 stars per cubic light year.

Accordingly, the pulsars can be delivered in the most complex and exotic stellar connections. It is obvious that there were “change partners” and the collision. It was probably a result of such collisions, and champions were formed by mass: a cluster Terzan 5 contains two pulsars, by weight exceeding twice the mass of our Sun. Hitherto the most “severe” was considered a pulsar mass exceeding our Sun to 1.68 times.

Astronomers believe that pulsars heavyweights have formed in a collision with a smaller pulsar red giant.

The very existence of such a massive pulsars allows astronomers to exclude certain assumptions about the structure of the objects of this kind: in particular, now just to say that this is not star in “neutron shell,” and filled with a viscous substance, consisting of quarks.

According to researchers who have studied the cluster, 24 of the pulsar – is not the limit. You may be able to detect and even more: 13 new pulsars in orbit around other ordinary stars (thus forming a steam system), and there is reason to believe that Terzan 5 may exist and such pairs, as a pulsar – black hole or a pair of high-speed millisecond pulsars.

However, the lock signal from the rotating binary system – a daunting task that requires to address the enormous computing power.
