Bounds on KSVZ axions from high mass star evolution

In this paper we study the effects of axions on the theoretical stellar evolution of a 10 solar mass star from the Main-Sequence stage to a likely final stage. We found that if the axion mass is less than 0.1 eV, an acceptable stellar evolution model which is consistent with observations is derived. If the axion mass is larger than 0.1 eV, such a star has a significantly different behaviour at the later stages of the evolution in the H-R diagram compared with a star without axions. The structure variables change greatly which is in contradiction with the observations.
