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.

'The very diverse strands are, however, brought together in a comprehensive, magisterial survey by Stan Owocki of the physical processes driving the outflows from stars and planets - ranging from the CAK formalism of the line-driven winds of massive stars, through the solar corona and wind, spin-down, planetary winds and mass loss, followed by a discussion of magnetospheres of stars and planets. The proceedings continue with a section on observational evidence for winds, led by reviews on low-mass stars, high-mass stars, and planets … Conference proceedings containing reviews and short communications giving a snapshot of current work are often suggested as a good means for beginners to get started in a new field; the present volume gives entry to three.'
