Probing the XUV environments of small comma nearby transiting planets

As both the software and hardware for detecting exoplanets has improved inrecent years, the population of small exoplanets in the Solar neighbourhoodknown to transit their star has increased significantly. Models suggest thatsuch planets may be the rocky remains of once much larger planets that werestripped of their outer envelope due to the intense level of high energyradiation impacting their atmosphere. We propose to study five nearby stars thatare known to host one or more planets of Earth and superEarth size, in order tocharacterise their high energy environment, and provide results to complementfuture atmospheric studies with instruments such as HST and JWST. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
