Abstract: (APS)

We calculate the bremsstrahlung emission rate of axions from a degenerate but weakly coupled plasma, using a Debye structure factor to take account of the nuclei correlations. This result pertains to axion emission from red giants near the helium flash and thus could be used to make a previous bound precise which involves the suppression of helium ignition in red giants by axionic energy losses.
