NUV transits probe a variety of exoplanet phenomena including atmosphericescape vertical distribution of aerosols and interactions of the planetaryatmosphere with a stellar wind. XMM hosts one of the three most powerful NUVtelescopes and with the longest orbital period is best suited to monitoringexoplanet transits in the NUV. These transits can be up to four times deeperthan the optical transit and show tentative trends with planet equilibriumtemperature and mass loss rates. We propose to observe five transiting hotJupiters that will fill gaps in the range of exoplanet equilibrium temperaturesprobed to date. We will also use the EPIC cameras measure the X-ray luminosityof the exoplanet host stars measuring the photoevaporative mass loss rates of each hot Jupiter. [truncated!
