Magnetic fields play a crucial role in the birth, evolution and variability of stars. From atmospheric structure to flares, the presence of magnetic fields has a direct or indirect influence on recorded data and on the properties deduced from observations.

In the recent years, the new generation of high-resolution spectrometers and spectropolarimeters led to an increasing number of publications focused on measurements of magnetic fields of the Sun stars and low-mass stars. Those require innovative techniques and state of the art models, and raise fundamental questions regarding stellar magnetic fields: how are they generated? How do they evolve? How do large-scale and small-scale fields relate to one another? How do those magnetic fields affect the habitability and evolution of planetary systems?

In this session, we aim at addressing those questions by inviting experts on magnetic fields in the Sun and low-mass stars.
