SUMMARY:IAU G5: Exo-space weather: The impact of stellar activity and outfl
 ows on the escaping atmospheres of exoplanets
DESCRIPTION:IAU G5: Exo-space weather: The impact of stellar activity and o
 utflows on the escaping atmospheres of exoplanets\nProf. Aline Vidotto\n\n
 Activity of cool dwarf stars can reveal itself in the form of       high-e
 nergy radiation (eg, enhanced X-ray coronal emission,       flares) and pa
 rticles (eg, winds, coronal mass ejections).       Together, these phenome
 na shape the space weather around       (exo)planets. Because most of the 
 known exoplanets have       significantly closer orbital distances than so
 lar system planets,       they are often embedded in much harsher particle
  and radiation       environments, leading to stronger interactions betwee
 n the       exoplanet and its surrounding environment. In this talk I will
        present an overview of how stellar activity and outflows can       
 induce and shape atmospheric escape in exoplanets. I will focus       most
 ly on close-in gas giant planets, whose escaping atmospheres       are som
 ewhat easier to observe. I will then discuss how the       observability o
 f atmospheric escape, through spectroscopic       transits, evolve on bill
 ions of years timescales.
