Resumo
During the observation of the 4th November 2003 large solar flare, a new and intense spectral component was observed with a maximum lying in the terahertz range. The origin of such component is still unknown, constituting a problem that goes beyond the application of canonical models used to describe the well-known microwave spectrum observed at frequencies below 100 GHz. In this work we investigate a possible contribution to the terahertz synchrotron emission in solar flares from positrons produced by Drell-Yan process in proton-proton collisions in the solar- atmosphere. © World Scientific Publishing Company.
