The Netherlands, scientists reported that the double Star J1906, for which they observed more than 5 years, disappeared from the field of view of the telescope in Arecibo Observatory. Astrophysics associated with the disappearance of the stars of the geodesic procession. Again see the object, scientists will be able to in about 160 years, and this is 2157.

The pulsar J1906 was discovered in 2004 by researchers Arecibo Observatory in Puerto Rico. This is – a tiny, but very dense neutron star is relatively recent, about 100 thousand years ago in the explosion. The space object is located at a distance of 25,000 light-years from Earth in the star cluster Terzian 5. Weight pulsar is about the same as that of the Sun, with a diameter of 10-20 kilometers.

At the moment, the pulsar disappeared. Emitted by them as they rotate pulsating signals now bypass the Earth. How to calculate the researchers, this phenomenon can be explained by a kind of precession: a dying star dived into a dent in space-time generated by its own orbit. Now J1906 «light” somewhere else and will shine for a while.

The tiny, but it has a huge mass of the pulsar tightly confined to a very close orbit to another star.

The force of attraction between two objects is so great that generates waves and warps space, causing tremors pulsar.

By tracking the motion of the pulsar for nearly five years, astronomers have determined its mass, and calculated the gravitational perturbation. But then the pulsar disappeared.

The emitted them as they rotate pulsating signals now bypass the Earth. How to calculate the researchers, this phenomenon can be explained by a kind of precession: a dying star dived into a dent in space-time generated by its own orbit.

Professor Dzhoeri van Leeuwen from the Netherlands Institute for Radio Astronomy says that pulsars, possessing mass as our sun in diameter, typically do not exceed 10-20 kilometers. When neutron stars occur in binary systems, they fall into the domain of applicability of Einstein’s general relativity and should generate around themselves undulating surface curvature of space-time – much like the ripples from a stone thrown. Such curvature, while existing only in theory, are called gravitational waves, and scientists are hoping to discover them once actually. It seems that it was done.

The study was published in “Astrophysical Journal” and presented at the 225th meeting of the American Astronomical Society.
