Axionlike particles produced in the core collapse escape from the star and decay into photons that can be observed as a delayed and diffuse burst. We discuss the time and angular distribution of such a signal. Looking into the future, we also estimate the possible improvements caused by better gamma-ray detectors or the explosion of the red supergiant Betelgeuse in a supernova event. 000075829 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FPA2015-65745-P$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 690575-InvisiblesPlus$$9info:eu-repo/grantAgreement/EC/H2020/690575/EU/InvisiblesPlus/InvisiblesPlus$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 674896-ELUSIVES$$9info:eu-repo/grantAgreement/EC/H2020/674896/EU/The Elusives Enterprise: Asymmetries of the Invisible Universe/ELUSIVES 000075829 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000075829 590__ $$a4.368$$b2018 000075829 591__ $$aASTRONOMY & ASTROPHYSICS$$b17 / 69 = 0.246$$c2018$$dQ1$$eT1 000075829 591__ $$aPHYSICS, PARTICLES & FIELDS$$b7 / 29 = 0.241$$c2018$$dQ1$$eT1 000075829 592__ $$a1.703$$b2018 000075829 593__ $$aPhysics and Astronomy (miscellaneous)$$c2018$$dQ1 000075829 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000075829 700__ $$aMalta, P.C. 000075829 700__ $$0(orcid)0000-0002-1044-8197$$aRedondo, J.$$uUniversidad de Zaragoza 000075829 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
