Understanding and Modeling Solar Eruptions: Where Do We Stand? 



Tibor Török 
Predictive Science, Inc. 
Solar eruptions, which are observed as prominence eruptions, flares and coronal mass ejections (CMEs), are the largest energy release processes in the solar system and the main driver of space-weather (SW) disturbances at Earth. While we have seen tremendous progress in both observations and modeling of solar eruptions over the past decades, there remain a number of open questions, such as of (i) the exact nature of the pre-eruptive magnetic configuration, (ii) the physical mechanisms that trigger and drive eruptions, and (iii) the conditions that determine SW-relevant CME properties. In this talk, I will discuss our current understanding of these fundamental aspects of solar eruptions, and how we can employ numerical simulations to study them.
