A Universal Bound on QCD Axions from Supernovae
Konstantin Springmann, Michael Stadlbauer, Stefan Stelzl +1
We identify a new production channel for QCD axions in supernova environments that contributes to axion emissivity for all models solving the strong CP problem. This channel arises…

From Supernovae to Neutron Stars: A Systematic Approach to Axion Production at Finite Density
Konstantin Springmann, Michael Stadlbauer, Stefan Stelzl +1
We present a systematic study of QCD axion production in environments with finite baryon density and temperature, implying significant changes to axion phenomenology. Within heavy…
