    Context. A peculiar atmospheric feature was observed in the equatorial zone (EZ) of Jupiter between September and December 2012 in ground-based and Hubble Space Telescope (HST) images. This feature consisted of two low ...
  • An enduring rapidly moving storm as a guide to Saturn's Equatorial jet's complex structure 

    Sanchez-Lavega, Agustin; García Melendo, Enrique José; Perez-Hoyos, Santiago; Hueso, Ricardo; Wong, Michael; Simon, Amy A.; Sanz-Requena, Jose Francisco; Antuñano, Arrate; Barrado-Izaguirre, Naiara; Garate-López, Itziar; Rojas, Jose Félix; del Rio-Gaztelurrutia, Teresa; Gómez-Forrellad, Josep M.; de Pater, Imke; Li, Liming; Barry, Trevor (2016-11-08)
    Article
    Open Access
    Saturn has an intense and broad eastward equatorial jet with a complex three-dimensional structure mixed with time variability. The equatorial region experiences strong seasonal insolation variations enhanced by ring ...

    Article
    Open Access
    We describe a huge planetary-scale disturbance in the highest-speed Jovian jet at latitude 23.5°N that was first observed in October 2016 during the Juno perijove-2 approach. An extraordinary outburst of four plumes was ...
  • PlanetCam UPV/EHU: a two-channel lucky imaging camera for solar system studies in the spectral range 0.38-1.7 µm

    We present PlanetCam UPV/EHU, an astronomical camera designed fundamentally for high-resolution imaging of Solar System planets using the “lucky imaging” technique. The camera observes in a wavelength range from 380 nm to ...
  • Shallow water simulations of Saturn's giant storms at different latitudes 

    García Melendo, Enrique José; Sanchez-Lavega, Agustin (2017-04)
    Article
    Open Access
    Shallow water simulations are used to present a unified study of three major storms on Saturn (nicknamed as Great White Spots, GWS) at different latitudes, polar (1960), equatorial (1990), and mid-latitude (2010) ...
