What else can I help you with?
Do all black holes have accretion disks?
Not all black holes have accretion disks. The presence of an accretion disk depends on the black hole's surroundings and whether it is actively consuming nearby matter.
Why do stars of galaxy's only orbit black holes in 2 dimensions and never totally in gulf the black hole?
because the black holes that they think are at the center of galaxies most likely have rotation, and the stars around it orbit the black hole somewhat like an accretion disc.
What is a burst of light from a black hole?
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
Will you explain about the outflow from the accretion disc?
Whats an accretion disc? Accretion disc is a disc of matter that falls on the black hole. It rotates around it rapidly, heating up and emitting radiation. Jets are due to twisting magnetic fields that if there are appropriate conditions cause particles from the disc to escape along its axis, forming jets.
What is an accretion disc?
An accretion disc is a structure formed around a central object, often a black hole or a young star, as it gathers material from its surrounding environment. The material in the disc spirals inward due to gravity, releasing energy in the form of heat and light. Accretion discs play a key role in powering some of the brightest phenomena in the universe, such as quasars and X-ray binaries.
Can black holes grow and how?
Black holes can increase in mass (and therefore size; the diameter of a black hole's event horizon is directly proportional to its mass) by accretion, or taking in additional matter and/or energy.
Was the earth formed by black holes scattered throughout the galaxy?
No. Earth was formed by the accretion of material in the protoplanetary disk around the newly formed sun. Black holes were not involved.
Why are black holes swirly?
The "swirly" part of the black hole you are referring to is called the accretion disk which consists of the matter being attracted to the black hole.
What is a spinning disc of material that forms a solar system?
accretion disc
What is the accretion disk of a black hole and how does it contribute to the feeding process of the black hole?
The accretion disk of a black hole is a swirling disk of gas and dust that orbits around the black hole. As material from the disk falls towards the black hole, it heats up and emits energy in the form of X-rays and other radiation. This process of material falling into the black hole through the accretion disk is how black holes "feed" and grow in mass.
Why wouldn't an accretion disk orbiting a giant star get as hot as an accretion disk orbiting a compact object?
An accretion disk is heated by friction and compression, both of which are greater for material falling into a compact object as the material is forced into a smaller space. The hottest accretion disks would be found around black holes.
Do black holes form X-ray energy?
It could be said that black holes form X-ray energy. As gases gather and become accelerated and compressed in the accretion disc, they get hotter and hotter. By the time these gases cross the event horizon, they can be generating (emitting) X-rays. The black hole itself doesn't emit the X-rays because nothing can escape its intense gravity. Not even light. But the X-rays are a result of the effect of the black hole's gravity.
