A kutatási téma leírása:
(Macro)spicules are one of the longest studied yet unsolved phenomena of small-scale solar atmospheric dynamics. Since the discovery of spicules a number of theories have been developed to model the generation, propagation and energy transport capability of spicules. The key question is whether these highly collimated magnetised plasma jets are indeed able to supply the measured mass flux of solar wind. Their big cousins, macrospicules, were discovered more recently. They are less ubiquitous when compared to spicues, however, their extent is often an order of magnitude larger. Therefore, their role may be also key in solar wind flows. This project is about to study the properties of (macro)spicules and model their generation and propagation by means of magnetohydrodynamic wave physics. The study will involve observational data analysis using high spatial, temporal and spectral resolution telescopes and numerical simulations by means of our state-of-the-art numerical code.
This project requires interest in taking observations by either ground- or space-based telescope. Therefore it is expected that the student may undertake such work at ground-based solar observatories. Further, the project also likely requires collaboration with colleagues from Solar Physics and Space Plasma Research Centre (SP2RC), University of Sheffield (UK). Therefore it is anticipated the student to spend some more extensive time at SP2RC within the framework of Erasmus+ or otherwise.
