Magnetic reconnection sustains the mass budget of the solar wind

Le résumé fourni par la source

The solar wind originates from regions of open magnetic fields on the Sun, but the relevant processes remain unsolved. We present a self-consistent numerical model of the source region of the wind, in which jets similar to those observed on the Sun naturally emerge due to magnetic reconnection between closed and open magnetic fields. In this process material is transferred from closed to open field lines and fed into the solar wind. We quantify the mass flux through the magnetic field connected to the heliosphere and find that it greatly exceeds the amount required to sustain the wind. This supports a decades-old suspicion based on spectroscopic observations and shows that magnetic reconnection in the low solar atmosphere could sustain the solar wind.
