Generation of solar coronal jets by 3D MHD simulations
Abstract
In the solar atmosphere, jet-like features are observed over a broad range of spatial and temporal scales. Recent solar missions (e.g. STEREO, Hinode, ...) have recently provided ground breaking observations of these active events. The high spatial and temporal resolution of the Hinode observations yields new insights into the origins of coronal jets, and provides detailed data that can be used to test and refine models. Despite their name, jet structure may not be fully formed by bulk flows. Physical process such as conduction and compressive wave may also explain many observed features. Numerical models have therefore appears as important tools to understand the underlying physics of these dynamic events. In this review, I will detail the results of several recent numerical experiments of the trigger of coronal jets. I will show that magnetic reconnection is the key process and I will discuss how 3D simulations are modifying our previous understanding of the driving process of solar jets.
