New star-pulsar emits just two types of radiation

Scientists have discovered a strange star, may surprisingly spontaneously switch between two different types of emissions: hard X-ray emission and an intense emission of radio waves in space. Although by themselves these two radiation is not unusual for the stars and the universe is a set of objects that are in the rotation and emit X-rays and radio waves, have not opened a single object that is to throw out the two different radiation immediately.

According to experts, the closest example of the similarity of the new object is a star, which at one stage of its evolution, emit X-rays, and the other — the radio waves. A new star is on his classification of a pulsar and immediately emits two types of emissions. Initially, experts suspect that they are dealing with the two are very close to each other objects, but later it was confirmed that the object is, after all, one.

"When we looked at previously published scientific publications, trying to find something similar to our facility, we have found nothing. While we certainly can not explain what can be associated emissions of this duality, but most likely, it is due to the unique magnetic shell star which is under the influence of some unknown reason can quickly switch between different states, "- says Wim Hirmshem, an astronomer at the University of Amsterdam.

According to him, as long as such changes in the magnetosphere of stars is very poorly understood by science.

A new star was classification number PSR B0943 +10. According to experts, its age is about 5 million years, and one full rotation on its axis makes the object for 1.1 seconds, which is slow enough for young pulsars. Changing the types of radiation in the star once a second. From the earth this strange object is removed by 3000 light years.

Exploring unusual pulsar is by x-ray Telescope European Space Agency's XMM-Newton, as well as ground-based telescopes in the Netherlands and India.

According to scientists, amazing looks that stellar magnetosfera can very quickly move to different states, producing a single type of emission, then the other. Now scientists have no answer to the question of what triggers these changes in a magnetic medium-star pulsar.
