Weiss (CXC) The motion of ultra-fast jets shooting out from a candidate black hole star system have now been documented by observations from the orbiting Chandra X-ray Observatory. In 1998, X-ray source XTE J1550-564 underwent a tremendous outburst. Jets of material sent streaming into space at near light-speed impacted existing gas heating it so much it glowed in X-ray light. The panels on the left of the above image show in X-rays that the hot spots have moved out by more than three light years in the time since the explosion, with the left jet recently fading below detectability. The drawing of the right depicts the binary star system that likely produced the X-ray jets, with a normal red star on the left dumping matter into an accretion disk around the black hole on the right. The jets are thought to be emitted along the spin axis of the black hole.
Hi Wet1 Hi all i have not undestod how gas or matter may break the black hole gravitational force and go away from it. may someone explain? Bye Lund.Please Register or Log in to view the hidden image!
Welcome to sciforums, Lund. Please Register or Log in to view the hidden image! While the process is not completely understood, it is thought that infalling material, from an accreation disc is the start. As this material loses angular momentum and falls towards the black hole it is heated. Anything that goes beyond the event horizon is gone. Before it reaches the event horizon is when material can escape. It is thought that black holes have huge magnetic feilds of force. These field lines affect the escaping radation gathering it at the poles of the magnetic feilds. This is propelled at near light speed from the poles. The force of gravity pulls us towards the centre of the earth. Only objects with very high speeds, like rockets, can escape earth's gravity. Black holes have so much mass and such a high density that nothing, not even light can escape from them. As light cannot escape from black holes, we cannot see them directly. Sometimes, material surrounding a black hole can be sucked in by it's huge gravitational force. As it falls into the black hole, it heats up and gives off radiation. Often the material gets so hot it emits in the X-ray, rather than visible light. Please Register or Log in to view the hidden image! Some of these jets can be seen in the X-rays of the giant radio galaxy CENTAURUS-A. The pink blobs extending off to the top left of the picture are hot spots in the jet which carries a huge amount of kinetic energy and mass. Jets of radation
Hi So pheraps i have understand something : 1) A black hole generate an intense magnetic field porbably the event orizont generate it ? or black h. may have thomething that have a + or - to generate a field? 2) an electron or proton in the event orizont is accellerate bay the magnetic field and generate x ray or others electromagnetic waves while is going away from the event orizon. Does it may go? 3) a magnetic field is not distorted by the intense gravitational force ? , it seem by the picture to be stright . Thank all Lund
