Paradoxically PULSAR: AGE PROBLEMS

Unusually slowly rotating pulsar is paradoxical: it seems he's older than a supernova explosion, which would have to rise.
Pulsars are called small powerful sources of radiation fluxes. These small body releasing a strictly periodic pulses, so that in the late 1960s, when they were discovered, some time this result remained classified because there was a suggestion that they have an artificial origin.

Now we know where they come from. It is believed that when a large star is approaching the moment of death and supernova explodes, its upper shell explosion discarded, and the core collapses rapidly. If it is not enough mass to form a black hole, there is an extremely dense neutron star. Rapidly revolving, it becomes a pulsar: a neutron star of ...

Due to the rotation of the pulsar, these flows are visible only occasionally, when they are more or less directed towards the observer. Over time, the speed slows down, so does the frequency with which observed pulsating radiation. Accordingly, the period of the radiation coming flashes can be very accurately set speed, and with it - and the age of the pulsar.

It so happened at this time: observations in Scotland working astronomer Gene Vincent - Brunet (Vincent Hénault-Brunet) and his colleagues showed that the pulsar SXP 1062 rotates relatively slowly, and therefore has a fairly large age. On the other hand, the consideration of the clouds of gas and dust flying from the explosion of a supernova, which would seem to have created this pulsar showed that the crash occurred less than 40 thousand. years ago - very recently!.

Data on radiation obtained using X-ray space telescope XMM-Newton, and the study of gas and dust clouds carried by the optical Hubble.

Pulsar SXP 1062 is located in the Large Magellanic Cloud, a dwarf galaxy, the Milky Way companion. Against the background of other pulsars, typically make hundreds of revolutions per second, SXP 1062 unhurried wonder: calculations show that for a full revolution around its axis, it takes about 18 minutes ( the frequency of its surveillance of outbreaks of 1.062 s). That in itself makes him a rarity: the present time few such objects are known at intervals longer than a few thousandths of a second.

Perhaps this fact has something to do with the paradoxical mismatch ages of the pulsar and the supernova. Certain ideas about what caused this situation, there is no. Perhaps some factors that led to slow the rotation of the pulsar outside the box quickly. Perhaps he was born rotating unusually slowly. The authors findings promise to find the answer to these questions. Well, we'll tell you about the results to which they will come.
