Stellar magnetic activity and their effects on planetary environments
Aline Vidotto (Trinity College Dublin)

In this talk I will review some recent works on the magnetic activity of Sun-like stars, their winds and potential impact on surrounding exoplanets. Stellar magnetic fields drive space weather on (exo)planets, being responsible for the ejection of stellar winds and bursty events, such as flares and coronal mass ejections. Therefore, understanding the host star magnetism is a key step towards characterisation of exoplanetary environments. Although these environments may be potentially dangerous for a planet's atmosphere, the interaction between exoplanets and the host star winds can provide other avenues for planet detection and maybe even assess planetary properties, which would otherwise remain unknown.
