Photospheric flows as possible drivers of solar eruptive events
Coronal mass ejections (CMEs) and flares are large scale eruptive events that are among the most studied topics in solar physics due to their fundamental role in the release of energy, mass and magnetic field which can impact the Earth environment. Solar eruptive events can also happen on smaller spatial scales, like mini-filament eruptions, jets or nanoflares. In this presentation we show the photospheric flows at the footpoints of coronal jets. These flow characteristics are very common and seem to play a vital role in the energy build-up and its explosive release in the solar atmosphere. In addition, we study the photospheric magnetic field evolution which can give important clues on the driving and triggering of coronal jets.
