On the speed and acceleration of electron beams triggering interplanetary type III radio bursts

Original language description

Aims. Type III radio bursts are intense radio emissions triggered by beams of energetic electrons often associated with solar flares. These exciter beams propagate outwards from the Sun along an open magnetic field line in the corona and in the interplanetary (IP) medium. Methods. We performed a statistical survey of 29 simple and isolated IP type III bursts observed by STEREO/Waves instruments between January 2013 and September 2014. We investigated their time-frequency profiles in order to derive thespeed and acceleration of exciter electron beams. Results. We show these beams noticeably decelerate in the IP medium. Obtained speeds range from similar to 0.02c up to similar to 0.35c depending on initial assumptions. It corresponds to electron energies between tens of eV and hundreds of keV, and in order to explain the characteristic energies or speeds of type III electrons (similar to 0.1c) observed simultaneously with Langmuir waves at 1 au, the emission of type III bursts near the
