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 کاملIonosphere of venus: first observations of the dayside ion composition near dawn and dusk.
The first in situ measurements of the composition of the ionosphere of Venus are provided by independent Bennett radio-frequency ion mass spectrometers on the Pioneer Venus bits and orbiter spacecraft, exploring the dawn and duskside regions, respectively. An extensive composition of ion species, rich in oxygen, nitrogen, and carbon chemistry is idenitified. The dominant topside ion is O(+), wi...
متن کاملPlasma Observations near Venus
Prel iminary results of tbe measurements of the electroQ and ion components of plasma obtained by means of wide-angle detectors onboard the Venera-9 and Venera-l0 satell ites are presented. Stable electron and fluctuating ion fluxes were detected in the optical and corpuscular umbra. As a result of the plasma characteristics ob served at a few hundred kilometers above the optical umbra, we ref...
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 ...
