      Open Access
      Saturn’s convective storms usually fall in two categories. One consists of mid-sized storms ~2,000¿km wide, appearing as irregular bright cloud systems that evolve rapidly, on scales of a few days. The other includes the ...
    • A planetary-scale disturbance in a long living three vortex coupled system in Saturn's atmosphere

      Article
      Open Access
      The zonal wind profile of Saturn has a unique structure at 60°N with a double-peaked jet that reaches maximum zonal velocities close to 100 ms-1. In this region, a singular group of vortices consisting of a cyclone surrounded ...

      The zonal wind profile of Saturn has a singular structure in the latitude range 50ºN-65ºN planetocentric, with a double peak that reaches maximum zonal velocities close to 100ms-1[1]. A survey of Cassini ISS images ...
    • 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 ...
    • Particle in cell simulation of electrostatic waves in Saturn's magnetosphere

      [ANGLÈS] The characteristics of electrostatic waves are investigated using PIC simulations of a four component plasma: cool and hot electrons, cool ions and an electron beam. The velocities are defined by Maxwellian ...
    • Reduction of Saturn orbit insertion impulse using deep-space low thrust 

      Fantino, Elena; Flores Le Roux, Roberto Maurice; Peláez Álvarez, Jesús; Raposo-Pulido, Virginia (American Institute of Aeronautics and Astronautics, 2020-02-17)
      Article
      Open Access
      Orbit insertion at Saturn requires a large impulsive manoeuver due to the velocity difference between the spacecraft and the planet. This paper presents a strategy to reduce dramatically the hyperbolic excess speed at ...
    • 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) ...
