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…
Constraining Light QCD Axions with Isolated Neutron Star Cooling
Antonio Gómez-Bañón, Kai Bartnick, Konstantin Springmann +1
The existence of light QCD axions, whose mass depends on an additional free parameter, can lead to a new ground state of matter, where the sourced axion field reduces the nucleon e…
