What else can I help you with?
Does a accretion spin?
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.
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.
What is disturbed by an outside explosion for it to cause an accretion disk?
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
How does an accretion disk around a neutron star differ from an accretion disk around a white dwarf?
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.
How fast do quasars spin?
Quasars, which are powered by supermassive black holes at the centers of galaxies, can spin at significant fractions of the speed of light. Their rotational speeds can be over 90% of the speed of light, influencing the dynamics of the surrounding accretion disk and the jets they emit. This high spin rate can enhance their luminosity, making quasars some of the brightest objects in the universe.

What would happen to a neutron star with an accretion disk orbiting in a direction opposite to the neutron star's spin?
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.

What may form an an accretion disk?
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.
A solar system may form from a spinning disk of a material called?
accretion disk
What an accretion disk may eventually form a what?
Solar system
What may an accretion disk eventually form?
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.
When a is disturbed by an outside explosion it may form a accretion disk?
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
When a..... is disturbed by an outside explosion. It may form an accretion disk?
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
How the rocky inner planets were formed?
By "accretion" of "planetesimals" from the "protoplanetary disk".
When an... is disturbed by an outside explosion it may form an accretion disk?
nebula
