Abstract
Recent missions have revealed that young solar-like planet hosts produce frequent superflares, which may have profound effects on the ability of terrestrial planets to retain their atmospheres. Observations also suggest that superflares are associated with filament or prominence eruptions that signify coronal mass ejections (CMEs). X-ray and EUV emission from superflares and dynamic pressure exerted by CMEs on exoplanets influence atmospheric chemistry and heating. In order to develop theoretical models of such events and assess their impact on habitable environments, we propose to perform a multi-wavelength campaign to observe various forms of magnetic activity of a young (~ 100 Myr) solar analog, EK Dra known to produce frequent flares and filament eruptions.
