  The Sun is a well-studied astrophysical source of axion-like particles
(ALPs), produced mainly through the Primakoff process. Moreover, in the Sun
there exist large-scale magnetic fields that catalyze an additional ALP
production via a coherent conversion of thermal photons. We study this
contribution to the solar ALP emissivity, typically neglected in previous
investigations. Furthermore, we discuss additional bounds on the ALP-photon
coupling from energy-loss arguments, and the detection perspectives of this new
ALP flux at future helioscope and dark matter experiments.
