Accretion disk?

[Demon of Elru]

Just curious before I buy, do black holes generate accretion disks?

[OuijaMawl]

No they do not yet have this capability in the game. It is something to look forward to in the future for the game.

Thank you.

i have sort of created on by putting a large star like Betelgeuse in the roche limit using orbit

I've seen custom made black holes that have accretion disks and relativistic jets; but they are not there by default.

Those would likely have been made in the same manner as the poster above you has stated or by putting in a ring of materials around the said black hole. The game doesn't support the conservation of momentum in a way that would make these discs be naturally forming in the game. As for jets I've only seen those available when using Pulsars

This black hole has jets and an accretion disk. I have played this sim and can confirm that the accretion disk doesn't come from the star.

This is not an accretion disk as these fragments are not coming together in any way around the black hole they simply orbit as a ring of material. I can speed this sim up to days a second or faster and the material will just spin around the hole never getting any closer to the center of gravity.

Second there is literally a star in orbit here around this black hole it definitely not outside the Roche Limit of the black hole and is shedding the material that is creating the ring in the first place which is exactly the process I was referring to in my last post. The person who wrote the description also states that it is "eating a star"

I see how the jets were made by increasing the magnetic field to insane numbers, this is just a pulsar effect on a black hole object.

Delete the star and look at the black hole from a camera angle of -42.5 degrees. There is an accretion disk.

This is still not accretion material, what I see at increased angles looks more associated with the jet texture than the black hole, I can decrease the magnetic field of the black hole to 0 and this effect vanishes completely.

I am aware that the black hole is not making the accretion disk. It is just a render. The point is that an accretion disk effect has be made by people. These seem to be made using an external editor because I tried to recreate the effect but it didn't work.
