Found the smallest black hole

Found the smallest black hole Facts

The smallest black hole is detected by X-rays, called palpitations because of its similarity to the electrocardiogram. She was given the name IGR J17091-3624. A hole is referred to the binary system, in which a normal star rotates with the black hole, weighing three times less than the mass of the Sun.

Aware of only one similar star system — GRS 1915 +105, which also consumes less gas with stars shine. This system exceeds the IGR J17091-3624 to 5 times.

Many binary systems with black holes is highly structured, but only two, IGR J17091-3624 and GRS 1915 +105, is characterized by fluctuations, which are called by astronomers "heartbeat." Model "heartbeat" explains the accumulation and subsequent ejection of matter from the accretion disk. Strong magnetic field around the radius of the black hole gas emitted in two opposite directions at the speed of light. Flows occur at the height of emissions. Changes in the X-ray spectrum at each "hit" show that the inner part of the disk emits enough radiation to push the gas and stop emissions, thereby "draining" the hole. After this "weakened" internal drive again gaining brightness and temperature sufficient to restart the cycle emissions. In the solar system, GRS 1915 +105 cycle occurs every 40 seconds, and in IGR J17091 — 8 times more often (data obtained from orbiting X-ray observatory RXTE).
