Does a non rotating BH have an accretion disc?
An accretion disc is a structure formed by swirling matter around a central object, such as a black hole or a young star. The matter in the disc is gradually pulled towards the center by gravity, causing it to spin faster and heat up due to friction.
Accretion discs are commonly observed around black holes. As matter falls towards the black hole, it forms an accretion disc around it. The intense gravitational pull of the black hole causes the matter in the disc to heat up and emit radiation, making it visible to telescopes.
Not all black holes have accretion discs. Smaller black holes, known as stellar-mass black holes, are more likely to have accretion discs compared to supermassive black holes that reside in the center of galaxies. However, even supermassive black holes can have accretion discs if they are actively feeding on surrounding matter.
Accretion discs form around black holes because of the intense gravitational pull of the black hole. As matter falls towards the black hole, it gets caught in its gravitational field and begins to orbit around it. Over time, the matter in the disc loses angular momentum and falls towards the black hole, causing it to grow in size.
Yes, we can observe accretion discs around black holes using various telescopes and instruments. The radiation emitted from the accretion disc can be detected in different wavelengths, such as X-rays, infrared, and radio waves. By studying the properties of the radiation, we can learn more about the structure and behavior of the accretion disc and the black hole at its center.
