Yes. An accretion disk consists of material orbiting or spiraling into some central massive object.
Yes.
Accretion is the process by which matter is accumulated by gravitational forces. While the accumulation of matter can lead to the formation of objects that spin, such as stars and planets, accretion itself does not inherently involve spinning.
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.
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
An accretion disk around a neutron star is composed of gas and plasma spiraling into the dense neutron star due to its strong magnetic field and intense gravitational pull, leading to high-energy emissions. In contrast, an accretion disk around a white dwarf is typically composed of lighter elements like hydrogen and helium, with the white dwarf's lower mass resulting in lower energy emissions.
The central engine of a quasar contains a supermassive black hole at its core, which is surrounded by an accretion disk of hot gas and dust. The intense gravitational forces and high temperatures within the accretion disk lead to the emission of powerful electromagnetic radiation, making quasars some of the brightest objects in the universe.

The neutron star so affected wouldn't really notice. The mass of the neutron star is huge compared to that of the material in the accretion disk. And that matter, when it falls in, wouldn't really "slow" the spin of the star much unless there was a gigantic quantity of matter falling in and/or it acted over a very long period.

solar system Material that is in orbit around a massive central body is an accretion disk. This disk can eventually turn into a white dwarf star. An accretion disc may eventually form planets such as the ones in our solar system.
