This is a coordinated HST+XMM-Newton program to address the conditions that affect habitability on Earth-like planets around Sun-like stars. Both wavelength regimes (far-UV with HST, X-rays with XMM) are needed to constrain models sufficiently to represent realistic conditions. An approved TESS program for our targets will provide additional information on surface inhomogeneities (spots) and their sizes and locations so that that can be taken into account as well. The FUV and X-ray fluxes from young stars are erosive of a planet's atmosphere, particularly for hydrogen, but also for oxygen and nitrogen, both chemically important elements.
