An international team of astrophysicists from the University of Amsterdam and the Netherlands Institute for Radio Astronomy today announced that the binary pulsar, called «PSR J190 + 0746″ disappeared from sight.
He became invisible even to the most sensitive telescopes. Astrophysicists were able to study some of the characteristics of the binary pulsar J1906 shortly before the deformation of the space-time plane hid him from the field of view.
According to The Astrophysical Journal, the pulsar PSR J190 + 0746 is in the system, which is located in the globular star cluster “Terzian 5″. Distance from the Sun 7670 parsecs from Earth and – 25 thousand light years. The next time it can be seen only through 160 years.
«Pulsar is now out of sight, and it is now invisible for even the largest telescopes. We first observed as a pulsar disappeared as a result of the precession – say astrophysics – This cosmic top again to appear in sight, when the axis outline the full circle, but it can take up to 160 years. ”
Recall that in 2008 was discovered the anomalous precession of the rotation axis of the pulsar by a strong gravitational field of his neighbor. The observed effect is known as the spin precession, was predicted by Einstein some 90 years ago, but up to this point has not yet been observed. According to general relativity, two massive bodies circulating around, should cause the curvature of space, enough to shift the axis around which they revolve.
