The Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter (SolO) is providing novel and unprecedented observations of the solar corona and chromosphere, revealing us the details on the coronal structures not seen up to now. These observations are crucial for improving our understanding of the structure and dynamics of the sun's atmosphere. The main scientific objective of this PhD project is to study and characterize Coronal Mass Ejections ...

Coronal mass ejections (CMEs) are considered to be one of the main drivers of space weather. They consist of large-scale eruptions of magnetised plasma, originating predominantly from active regions in the low solar corona and are extremely common events. During solar maxima, they occur on a daily basis, at times exceeding 10 events per day. CMEs can affect space missions and when they propagate towards Earth and interact with the ...

This project focusses on the intiation and evolution of CMEs through observations and 2.5D MHD numerical modelling. Two models are used, one describes the initiation of the eruption and the other neglects the initiation phase by superimposing a high density/pressure sphere on a background solar wind. The effect of the initial parameters, such as the polarity of the CME, on its evolution can then be studied.The observational study concerns ...

Coronal Mass Ejections (CMEs) are huge expulsions of ionised gas, called plasma, from the atmosphere of the Sun into the interplanetary (IP) medium. At times, they propagate toward the Earth, eventually resulting in hazardous space weather conditions. Therefore, being able to forecast both the CME initiations and their trajectories is of crucial relevance for all space-born and ground-based systems that are affected by the space weather. ...

Since the advent of the Space Age, our society has become more and more susceptible to the conditions of the near-Earth space, which is primarily shaped by solar activity. Coronal mass ejections (CMEs) are the most energetic and largest scale solar eruptions and are the main drivers of severe space weather disturbances at Earth. When launched in rapid succession, CMEs can interact during propagation through interplanetary space, undergoing ...

Space weather refers to the physical and phenomenological state of natural space environments. It is often defined in a more limited sense as those conditions in the near-Earth space that affect human-made technology and biological systems in orbit. In both scopes space radiation is a key component of space weather. Solar energetic particles (SEPs) are one of the most severe radiation threats to space missions outside the Earth’s protective ...
