In the Crab Nebula pulsar found deadly

October 14, 2011 15:18

In the Crab Nebula in Taurus astrophysicists discovered an exploding star, which force us to reconsider the theory of gamma radiation from the star.

Gamma rays — a light with the highest energy generated by subatomic particles moving at near-light speed. Powerful sources of gamma-ray pulsars are rotating neutron stars formed after the supernova explosion.

Astronomers have found the center of the Crab Nebula pulsar, which emits gamma rays with incredible energy — more than 100 billion electron volts. This is an incredible figure, because existing theories gamma pulsars suggest abrupt cessation of emission of high-energy

Astronomers observe the brightest bursts of radiation emitted by the pulsar, located at a distance of 12,000 light-years from Earth. Outbreaks length of only 15 nanoseconds each (15 billionths of a second) fixed radio telescope in the town of Tidbinbilla (Australia).

Despite the fact that the pulsar

The pulsar B1937 +21 (he was the first millisecond pulsar) was discovered a few decades ago. B1937 +21 is known that emits high power electromagnetic pulses every 1,557 milliseconds. Such a violent eruption registered for the first time, reports New Scientist.

Pulsars are superdense remains of burned-out

Quirk of nature in the cube

Magnetar, pretending to be a pulsar, has puzzled astronomers

Using several large radio telescopes located on different continents, managed to clarify some of the amazing details of the "life" of a unique facility, opened in 2003 X-ray Observatory NASA Rossi (as transient anomalous X-ray pulsars) and the designation XTE J1810-197. Expected that XTE J1810-197 is a single rotating neutron star, which has a high-powered magnetic field — the so-called magnetars (magnetar).

However, despite the fact that all magnetars represent a very small class of objects, XTE J1810-197 and of magnetars was truly unique, capable of such tricks, which previously

Scientists point out that before the pulsar, which is called PSR B0531 +21, the graph of the photon distribution of the radiation in the energy An "obrubanie" in the high-energy part of the spectrum from what astronomers have concluded that some of the radiation, particularly gamma rays not recorded with the device, writes Lenta.ru.
