Question

Quizplus · Accepted Answer

X-ray busters are similar to novae as they both involve the rapid increase in X-ray emission due to material falling onto a compact object, such as a white dwarf in the case of novae and a neutron star or black hole in the case of X-ray busters. Planetary nebulae, type I and II supernovae, and hypernovae do not involve the same mechanism of X-ray emission and are therefore not as similar to X-ray busters.
