Новый пульсар делает 11 000 оборотов вокруг собственной осиA group of astronomers from Germany and the USA opened the brightest and the young of rapidly rotating stars. Researchers say the discovery as a very old and very young and rapidly rotating stars suggests that such objects can be significantly more common in the Universe than previously thought.

Rapidly rotating star or, to put it more scientific, millisecond pulsar, called J1823-3021A. It is located within a conglomerate of stars called a globular cluster with several thousand stars, distant from the Earth of about 27 000 light-years away in the constellation Sagittarius.

Pulsar emits incredibly dense beams of gamma rays of high energy, which was found this unusual object. Gamma emissions of a pulsar discovered space telescope NASA's Fermi working in the field of research of high-energy radiation in space. According to the analysis of emissions, the age of the pulsar at over 25 million years, which by the standards of pulsars very slightly. Most millisecond pulsars are the age of billions of years.

From the point vision scientists, extreme brightness precisely due to the young age of the object. In addition, experts say that if the age of pulsars can be counted in billions of years, then such objects in the Universe can be a lot, at least in globular clusters.

Paolo Fiere, study author and astronomer from the Institute of radio astronomy at the max Planck Institute in Germany, believes that in reality millisecond pulsars can form a previously unknown ways for the Universe pulsars may not be as exotic formations. "I suspect that the formation of pulsars - a kind of the tip of the iceberg that represents only a small proportion of the mysteries of the Universe," he says.

Pulsars are the remnants of massive stars, left after the explosion last and cowering under its own gravity to an incredible density. Density here is that all elementary particles there are only neutrons and electrons. Scientists say that when the object whose mass is comparable to the mass of the Sun is compressed to the size of the super-dense "stone" in diameter of 15-20 km, then under the action of centrifugal forces that object starts very quickly turning, throwing out beams of gamma radiation.

Ordinary pulsars rotate at a speed of 7 to 3750 rpm, but millisecond pulsars rotate much faster - up to 43 000 rpm. These rotating objects often coexist with the stars, a matter which they eat. Up to 80% of pulsars exist in binary systems.

Let's remind, that recently with the same telescope Fermi were discovered nine previously unknown gamma-ray pulsar. These pulsars are not thrown large bundles of energy, so they remained unnoticed. To open these objects were used new algorithms.

In respect of the pulsar J1823-3021A scientists say that he makes every minute of about 11 000 turns on its axis, that is, one full turn he does for 5,44 milliseconds (for comparison, the Earth is 24 hours). Strictly speaking, German scientists were not opened J1823-3021A. Technically, its radiation has been known since the 90-ies, but until recently the source of this radiation remained unclear.
