Winds of Stars and Exoplanets (Iau S370)

Winds form an integral part of astronomy ¿ from regulating rotation of stars through enriching galaxies with fresh materials. Outflowing winds persist during the entire lives of stars and play a key role in shaping the exoplanet demographics we observe. In massive stars, their winds are a vital ingredient of their evolution, from the main sequence to the pre-supernova stage, determining black hole masses as measured from gravitational waves. In the case of low-mass stars, their winds dictate rotational evolution, which affect angular momentum distribution within the stellar interior and thus the generation of magnetic fields. In the case of planets, winds take the form of atmospheric escape, which can strongly affect their atmospheric evolution. IAU Symposium 370 brings together researchers on winds of exoplanets and stars, including the solar wind, to share insights into the physics and modelling tools used by these different communities.
