HST observations show that three of the brightest transiting exoplanets areevaporating (HD209458b, HD189733b and GJ436b) and models suggest that theevolution of closein lowmass planets may be dominated by this mass loss.Simultaneous Xray and ultraviolet observations of planetary transits are neededto constrain selfconsistent models of the exoplanetary winds. Here we proposetransit observations of four bright exoplanets with XMM in order to determinemass loss rates.
