Of the Venus Ionosphere
• A two-dimensional, time-dependent, shock capturing single-sp•ies (O +)hydrodynamic odel of the Venus ionosphere, which solves the coupled continuity, momentum and energy _,•ons for the altitude range of 150 500 km and the solar zenith angle range of 0O 180 ø has been developed and is presented in this paper. It was again demonstrated thathe introduction of topside heat inflows leads to calcul...
متن کاملThe Venus Ionosphere and Solar Wind Interaction
The current state of knowledge of the chemistry, dynamics and energetics of the upper atmosphere and ionosphere of Venus is reviewed together with the nature of the solar wind-Venus interaction. Because of the weak, though perhaps not negligible, intrinsic magnetic field of Venus, the mutual effects between these regions are probably strong and unique in the solar system. The ability of the Pio...
متن کاملGiant flux ropes observed in the magnetized ionosphere at Venus
[1] The Venus ionospheric response to solar and solar wind variations is most evident in its magnetic field properties. Early Pioneer Venus observations during the solar maximum revealed that the Venus ionosphere exhibits two magnetic states depending on the solar wind dynamic pressure conditions: magnetized ionosphere with large-scale horizontal magnetic field; or unmagnetized ionosphere with ...
متن کاملModel Calculations of the Dayside Ionosphere of Venus Energetics
A model of the energy balance of the dayside ionosphere of Venus is presented. Calculations of the dayside electron and ion temperature profiles are carried out and compared with data from experiments on the Pioneer Venus orbiter. The coupled heat conduction equations for electrons and ions are solved for several values of the solar zenith angle. It is shown that thermal conductivities are inhi...
متن کاملWhistler-mode Propagation in the Collisional Ionosphere of Venus
Waves identified as whistler-mode waves have been observed in the nightside ionosphere of Venus by the Pioneer Venus Orbiter. These waves are propagating in a collisional, weakly magnetized ionosphere, and it has been argued that as such they should be damped through collisions, and the wave should not retain the characteristics of the whistler-mode because of non-linear modifications to the di...
