black hole gravitational effects
« on: July 12, 2012, 12:49:19 PM »
Hi folks, I was messing around with a large black hole, and found this effect after turning two large stars to dust:





Is there a name for this effect? It seems to be caused partly by tidal effects. The black hole is about 90m suns in mass, rotating at a very high rate, and has a diameter of less than a mm for reference, and the dust is orbiting from 0.95c to a little over c

an 'accreation disk' i guess. objects closer naturally orbit faster. (btw i don't think the rotation rate of the blackhole does anything.

The first screenshot is the Accretion Disk [Event Horizon] that orbits the Black Hole. The second screenshot looks like a Gamma Burst, but it could be the simulation looked on by side view.

Whats the weird blurred 'reflection' in the middle of both images?

The first one does look like an accretion disk and the second one is just looking at it from a side view.

It would be awesome to see what it looks like with Ubox3.

Thank you for the replies. the weird glow is some bug I have with the glow option, I'm not sure why it's there. The second image is a side view after the dust in the original photo stabilized.

I found my answer, on top of the tidal effects, it started off orbiting.. adding 4 clouds of dust in a square around the black hole creates a normal ring.

The first is indeed an accretion disk, the second, should be a quasar. Which is the same as a GRB, but for black holes, If I'm right, the Gamma Ray Burst is the moment a VERY large star collapses into a black hole, and emits lots of gamma rays during the process.

I'm probebly wrong on the quasar part; it has another name when particles, instead of electromagnetic waves are emited.

Just to clear up a bit on some terminology: a quasar is an active galactic nuclei, a supermassive blackhole at the center of a galaxy which chews up matter and spits out energy.
