- W4311894751 abstract "Axionlike particles (ALPs) can be produced by thermal processes in a stellar interior, escape from the star and, if sufficiently light, be converted into photons in the external Galactic magnetic field. Such a process could produce a detectable hard x-ray excess in the direction of the star. In this scenario, a promising class of targets is the red supergiants, massive stars which are experiencing the late part of their evolution. We report on a search for ALP-induced x-ray emission from Betelgeuse, produced via the combined processes of bremsstrahlung, Compton and Primakoff. Using a 50 ks observation of Betelgeuse by the NuSTAR satellite telescope, we set 95% C.L. upper limits on the ALP-electron (${g}_{ae}$) and ALP-photon (${g}_{aensuremath{gamma}}$) couplings. For masses ${m}_{a}ensuremath{le}(3.5--5.5)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}11}text{ }text{ }mathrm{eV}$, we find ${g}_{aensuremath{gamma}}ifmmodetimeselsetexttimesfi{}{g}_{ae}<(0.4--2.8)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}24}text{ }text{ }{mathrm{GeV}}^{ensuremath{-}1}$ (depending on the stellar model and assuming a value of the regular Galactic magnetic field in the direction transverse to Betelgeuse of ${B}_{T}=1.4text{ }text{ }mathrm{ensuremath{mu}}mathrm{G}$). This corresponds to ${g}_{ae}<(0.4--2.8)ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}12}$ for ${g}_{aensuremath{gamma}}>1.0ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}12}text{ }text{ }{mathrm{GeV}}^{ensuremath{-}1}$. This analysis supercedes by over an order of magnitude the limit on ${g}_{ae}ifmmodetimeselsetexttimesfi{}{g}_{aensuremath{gamma}}$ placed by the CAST solar axion experiment and is among the strongest constraints on these couplings." @default.
