Strong solar flares and coronal mass ejections, here defined not only as the bursts of
electromagnetic radiation but as the entire process in which magnetic energy is released …

This publication provides an overview of magnetic fields in the solar atmosphere with the
focus lying on the corona. The solar magnetic field couples the solar interior with the visible …

The European Union funded the FLARECAST project, that ran from January 2015 until
February 2018. FLARECAST had a research-to-operations (R2O) focus, and accordingly …

A workshop was recently held at Nagoya University (2017 October 31–November 2),
sponsored by the Center for International Collaborative Research, at the Institute for Space …

Solar flares are extremely energetic phenomena in our solar system. Their impulsive and
often drastic radiative increases, particularly at short wavelengths, bring immediate impacts …

A clear understanding of the nature of the pre-eruptive magnetic field configurations of
Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting …

An introduction into the subject of solar physics has been previously presented in the
textbook Physics of the Solar Corona by the same author, which covered most of the science …

Aims. We investigate the role of the accumulation of magnetic helicity and magnetic energy
in the generation of coronal mass ejections (CMEs) from emerging solar active regions …

Context. The discovery of clear criteria that can deterministically describe the eruptive state
of a solar active region would lead to major improvements on space weather predictions …

The relative magnetic helicity is a quantity that is often used to describe the level of
entanglement of non-isolated magnetic fields, such as the magnetic field of solar active …
