Abstract: A theoretical study is made to assess the importance of the solar EUV flux in the thermal energy balance of the Jovian thermosphere. A global averaged vertical temperature contrast in the thermosphere of 15K is calculated ...

Abstract: Specially prepared sections of pictures taken with the Mariner 10 television cameras are composited to show the time development of UV markings at various locations on Venus. A second series of composite pictures shows the ...

Abstract: We provide morphological and kinematic desc6ptions of the UV markings seen in the Mariner 10 imagery of Venus: the dark horizontal Y, bow-like waves, circumequatorial belts, subsolar disturbance, spiral streaks and bands, ...
