NASA discovers X-ray breakers by massive cosmic explosions



AKURAT.CO, Astronomers observe X-ray flashes caused by thermonuclear explosions in space. In 20 seconds as much energy is released as from the sun for 10 days.

The explosion occurred on the pulse surface of neutron stars and quickly turned with a strong magnetic field that fires the radiation of the poles, which is often equated with interstellar lighthouses. Neutron stars are the remnants of very dense stars that exploded towards the end of their lives as a supernova.

Last August, astronomers detected a sudden increase in X-rays that began around 10 am in J1808. NASA states that this is the brightest X-ray detected by NICER since the telescope was put into service in 201

Among the most unusual explosive elements, astronomers found that there were temporary pauses in increasing the brightness of X-rays. After this break, the X-rays start to get brighter. The scientists themselves are not sure why this happened.

The type of thermonuclear explosion observed by scientists is called the Type I X-ray explosion and occurs in the surface layer of neutron stars, which accumulate hydrogen and / or helium from companion stars. [19659002] In the case of J1808, the pulsar is part of a binary star system (twins) in which the other body is a brown dwarf class of astronomical objects larger than giant planets, but too small to be stars of brown dwarfs slices around the remnants of solid stars.

Every few years, the gas disks around these pulsars become so dense that the atoms in the gas lose their electrons or, in other words, ionize

This traps radiation and initiates an uncontrolled and widespread warming process. At some point, hydrogen gas begins to split off into the pulsar, forming a hot global ocean.

When the temperature and pressure on the deepening ocean floor rise high enough, the hydrogen nucleus begins to fuse and form helium nuclei, in which energy is generated in large quantities. This process is the same as in the core of our Sun, which triggers a star.
