Science Questions and Aims

The proposed multi-disciplinary ISSI team targets two key science questions in solar and stellar research:

1. How are coronal mass ejections initiated?
2. Can we use coronal dimmings to detect and characterize stellar mass ejections?

These questions will be addressed with an innovative two-pronged approach; namely, exploiting the unique
potential offered by coronal dimmings associated with coronal mass ejections (CMEs), and extending the recent
advances in the simulations and observations for solar eruptions toward the stellar case.

We have two main aims:

1. to better understand the initiation, magnetic configuration, and mass loss of CMEs through the investi-
   gation of the magnetic and thermodynamic evolution of the associated coronal dimmings. The team will perform detailed multi-disciplinary studies, combining observations and simulations and will relate these results to Sun-as-a-star observations to investigate the potential of coronal dimmings for detection and characterization of CMEs on solar-like stars;
2. to write a review paper on coronal dimmings and their relevance in better understanding and characterizing solar and stellar CMEs. This will be the first review on coronal dimmings, 45 years after their detection.
