Abstract

We consider the contribution of bremsstrahlung emission of axions to stellar energy losses. This process has a much weaker temperature dependence than previously considered axion emission processes. It is comparable to these processes in the sun, and for objects with non-degenerate core temperatures less than 85% that of the solar core, axion bremsstrahlung will dominate. We briefly consider the implications of these axionsemission losses for altering the evolution of old globular cluster stars.
