High resolution observations of solar jets from the photosphere to the corona.

Abstract

Abstract: Solar jets are ubiquitous, sharp-edged collimated plasma ejections that are detected in all layers of the Sun from the photosphere to the corona. Observed as impulsive events, jets can originate in all kinds of solar environments, from active regions to the quiet Sun. Occasionally, these jets interact with large scale solar filaments and can set them into oscillation, sometimes followed by instability and eruption. I will present high spatial, temporal, and spectral resolution observational studies of jets to probe the fundamental physical process behind them and integrate these observations with theoretical models. We use the coordinated observations from space-borne (SDO, IRIS) and ground-based (SST) telescopes. Space-borne telescopes provide the EUV/UV data for the outer atmosphere of the sun (chromosphere, transition region and corona), while ground-based telescopes give access to high resolution data for the inner solar atmosphere (lower chromosphere, photosphere) through H-alpha, Ca II, and Fe I lines. In this way, coordinated observations cover the solar atmosphere in multi-wavelength range from the photosphere to the corona through the chromosphere and transition region.
