According to the Unruh effect an observer who is has an acceleration ##g## will observe the temperature of the vacuum to be
$$T=\frac{\hbar g}{2 \pi c k_B}.$$
According to the equivalence principle the observer should measure the same Unruh temperature if he is sitting on a planet whose surface gravitational field has a strength of ##g##.
Is this correct?
As the Unruh and Hawking temperature are very similar does this mean that all gravitating bodies have a Hawking/Unruh temperature that could in principle be detected by a distant observer?
