WebBlack holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays. A supermassive black hole’s intense gravity can cause stars to orbit …
WebThis is 6% of mc2 for a nonrotating black hole, and up to 42% for a maximally rotating black hole. Therefore, the accretion e ciency for black holes can in principle be the highest accretion e ciencies in astrophysics. Unlike stars, for black holes all the emitted energy must come from the accretion disk.
