From Spicules to Coronal Jets: Origin, Dynamics and Their Contribution to Solar Atmospheric Heating

About this Research Topic

Solar jets, manifesting as multi-thermal elongated structures with various lengths from several to several hundred megameters and lifetimes from minutes to hours, have been found ubiquitous throughout the solar atmosphere from the chromosphere to the upper corona. Based on their different sizes, dominant temperatures and wavelengths they are observed, they have been given different names including spicules, surges, RBEs/RREs and EUV/X-RAY/White-light jets. Solar jets have often been found to be accompanied or associated with a number of different phenomena in the Sun including the p-mode oscillation, magnetic reconnections, (nano-)flares, filament (eruptions), corona mass ejections and transient events in the solar wind. Solar jets are also one of the perfect carriers or drivers of a wide range of MHD wave modes and incubators for a variety of instabilities that subjects for corona seismology and suggested to play important roles in the heating of the upper atmosphere of the Sun.

Since the first modern observations of coronal jets and macro-spicules in the solar atmosphere in the 1970s, the understanding of solar jets has been much advanced thanks to the development of MHD and plasma-astrophysics theories, the improvement of computational powers and the realisation of a number of state-of-the-arts observational facilities with high spatial and spectral resolution and temporal cadence. Though solar jets have been mostly observed in active regions, coronal holes, quiet regions and even the solar wind, many vital questions about their origin and nature are yet to be fully understood. These include but are not limited to:
* the triggering mechanism of jets at different scales
* the intrinsic relationship between jets with different scales
* their static and dynamic properties
* their correlation with different scales of solar flares and filament eruptions
* their relationship with the solar cycle and magnetic and helicity variations
* their relationship with different MHD wave modes
* the role of kink and Kelvin-Helmholtz instabilities in solar jets
* their interactions with other solar wind transient events

In this Research Topic, we search for and invite contributions of original and review papers with theory, numerical simulations, observations and machine learning studies of solar jets. The submitted papers would cover one to several aspects of any of the current research topics of solar jets, including the above listed ones. We especially encourage submissions on the origin, dynamics and contribution to solar atmospheric heating by solar jets.
