Title: Physics Potential of IAXO for Supernova Axions

Abstract:
The International Axion Observatory (IAXO) is the next-generation axion helioscope, designed to push the sensitivity to axion–photon couplings well beyond current limits. While primarily conceived to search for solar axions, IAXO and its intermediate stage, BabyIAXO, also offer a unique opportunity to detect axions produced in core-collapse supernovae.

In this talk, I will present recent results on the prospects for IAXO and BabyIAXO to detect a supernova axion burst. We show that these experiments can probe regions of parameter space inaccessible to solar searches, and that a nearby supernova — at distances of order ∼100 pc — could yield a detectable signal for couplings g_{aγ} ≳ 10⁻¹¹ GeV⁻¹. Such an observation would provide valuable insight into axion production in dense nuclear matter and shed light on key aspects of supernova physics, including pion abundance and the nuclear equation of state. The discussion will be framed within a broader overview of the IAXO project and its experimental capabilities.
