What the temperature of a black dwarf star?

Answer 1

It depends, the radiation that comes off of Black Holes weren't observed in a way we can measure. However, there were different measurements for the total kinetic energy being produced.

An example:

The higher you go up into the atmosphere the colder it gets, but the temperature increases due to the higher kinetic energy.

Answer 2

The temperature of a black hole varies massively, and is inversely proportional to size. The smaller a black hole found in space is, the greater its temperature. The hottest black hole in the universe will almost definitely be hotter than any temperature we have recorded on Earth. However, it is expected that a supper massive black hole (more than a million times the size of our Sun) can have very cold temperatures equal to near zero kelvin.

Answer 3

The "surface" of a black hole in this context is taken to mean the "event horizon". Theoretically at least, there will be nothing radiating out from the event horizon of the black hole and thus the temperature should be absolute zero (0 degrees Kelvin) by definition. However, the theory of "Hawking Radiation" from an incredibly thin layer just outside the event horizon should give rise to a temperature that is a few billionths of a degree above absolute zero, the actual temperature being dependent on the mass of the black hole. This would only apply if the black hole was completely on its own in space with no other matter falling into it. Where particles of matter are falling into a black hole, they can be accelerated up to speeds close to the speed of light and as these particles of matter rub against one another, the friction may produce temperatures of several million degrees.

Answer 4

There is no weather in a black hole. Black holes exist in space. Scientists are not sure what conditions exist inside a black hole. We know that space and time are severely distorted, but beyond that we know little. Quantum mechanics and general relativity come into conflict.

Answer 5

since there can be no motion in a singularity, by ordinary thermodynamic definitions the temperature must be absolute zero. however as singularities produce contradictions in many laws of physics, ordinary thermodynamics may not apply.

Answer 6

A black dwarf star is a theoretical endpoint in stellar evolution, where a white dwarf star has cooled down completely and no longer emits heat or light. Their temperature would approach absolute zero, near 0 Kelvin.

Answer 7

To be called a black dwarf star, a white dwarf has to drop to a temperature of at least 5 k (-450 f) i like rain.
