We present a one-dimensional model of the formation and viscous evolution of protoplanetary disks. The formation of the early disk is modeled as the result of the gravitational collapse of an isothermal molecular cloud. The disk's viscous evolution is integrated according to two parameterizations of turbulence: the classical alpha...

It has been proposed that the enrichment in noble gases found by Galileo in Jupiter's atmosphere can be explained by their delivery inside cold planetesimals. We propose instead that this is a sign that the planet formed in a chemically evolved disk and that noble gases were acquired mostly in gaseous form during the planet's envelope capture...

We perform a survey of the Visible and Infrared Thermal Imaging Spectrometer-Mapper (VIRTIS-M) images onboard the Venus Express space mission, at four narrow wavelength bands that target different altitude regions on the cloud deck of Venus' atmosphere (280–320, 365–400, 580–600, 900–920 nm). Our goal was to detect and characterize atmospheric...
