Dark Stars ??

You're right, John, a black hole is a surface of infinite redshift. The radiation detected from black holes is from gas falling towards the hole, accelerating, and getting hot enough to emit X-rays (given out long before reaching the event horizon).

Hawking radiation is a separate effect, and can be understood as arising because black holes have temperature, and therefore glow. Like a lot of black-hole related things this sounds counter-intuitive because we think of black holes as regions that "trap everything", but that's not strictly accurate. The significance of Hawking's result was that it could be seen "classically" as the glow of a warm body ("black-body radiation") or equivalently as a quantum effect involving particle creation (as explained previously in this thread). But Hawking radiation has never been observed - the "temperature" of known black holes is too low for the effect to be detectable.

Are there any researchers\theorists on this forum that have any updates on the current status of Black Strings and Black Rings?

These are analogues of our Black Holes in higher dimensions.

I was wondering what would be different for these two cases

[1] Radiation by virtue of accretion of infall of matter

[2] Hawking Radiation

from Observational and Theoretically perspectives
