Planet erosion by coronal radiation
According to theory, high energy emission from the coronae of cool stars can severely erode the atmosphere of orbiting planets. To test the long term effects of the erosion we study a large sample of planet-hosting stars observed in X-rays. The results reveal that massive planets (M_p sin i > 1.5 Mjup) may survive only if exposed to low accumulated
