The object is SAX J1808.4-3658, rotating 400 times a second on its axis. It is part of a neutron star system in which the pulsar steals a companion's material. The material is organized in an accretion disk and falls on the star periodically.

The flare is caused by this collision. When the material strikes the dense, warm neutron star, an energy explosion is thrown away. This is equivalent to the Sun's energy generated in only a few weeks in ten years.

Theories suggest that this process could take place within a few days, but these observations indicate that the process is at least longer for this system. The material spiraled in and collided with the pulsar in 12 days.

"These observations permit us to explore the structure and easily move the material inside the neutron star, as well as to study the structure of the accretion disk," said Adelle Goodwin, author of Monash University in a statement.

"The initial activity took 12 days for the disk to be hot in and material to spiral into the Neutron star and X-rays to be produced by using multiple, light-sensitive telescopes in various energies in the area of the accompanying star, at their outer bording.""

The composition of the disk is one way for the accretion length in this system. As the pulsar steals material from a star, hydrogen is usually the most abundant element in the stars. The second most abundant element, this disk is however 50 percent helium. The difference could be crucial for extending the "power-up" time.

In the Sagittarius constellation, SAX J1708.4-3658 is 11,000 light-years away.
