It is shown that whistler mode waves from the ionosheath of Venus are absorbed by Landau damping at the dayside ionosphere boundary. This process heats the ionospheric electrons and it may provide an important energy input into the dayside ionosphere. Cyclotron damping of the waves does not occur in the same region. However, Landau damping of ionosheath waves is apparently not an important energy source in the nightside ionosphere. Impulsive events in the nightside ionosphere seem to fall into… 
Model 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
A source of plasma turbulence at the ionopause of Venus
The simultaneous measurements of suprathermal ions and low frequency electric field signals at the ionopause of Venus by Pioneer Venus instruments suggests that they may be causally related. Linear
Lightning on Venus: Orbiter Detection of Whistler Signals (invited).
Recently Taylor et al. (1979a) presented preliminary evidence for lightning on Venus, based on Pioneer Venus orbiter detection of whistler mode signals as the spacecraft first traversed the nightside
Pioneer Venus plasma wave observations: The solar wind‐Venus interaction
We briefly describe the Pioneer Venus plasma wave instrument and continue with a discussion of wave observations throughout the typical. near-noon and near-midnight orbits. This is followed by a
The Solar Wind Interaction with Unmagnetized Planets: A Tutorial
The interaction of the solar wind with the Venus ionosphere induces currents which can substantially exclude the solar wind and IMF from the dayside ionosphere beneath the 'ionopause', where
A two-dimensional model of the nightside ionosphere of Venus: Ion energetics
The energetics of the nightside ionosphere of Venus are still not well understood. Rather large ion temperatures have been observed on the nightside. We have constructed a two-dimensional theoretical
Magnetic field control of the dayside ion temperatures in the ionosphere of Venus
Ion temperatures measured by the retarding potential analyzer carried aboard the Pioneer Venus Orbiter were sorted according to the ionospheric magnetic field conditions. It was found that the
Energetics of the dayside ionosphere of Venus
A reanalysis of the Pioneer Venus electron temperature data base showed a strong correlation between elevated electron temperatures and induced magnetic fields in the day side ionosphere above about
Observations of the dayside ionopause and ionosphere of Venus
Some of the principal features of the dayside solar wind ionosphere interaction at Venus are presented. The dayside ionopause and ionosphere are observed to respond dramatically to solar wind
Plasma waves and field‐aligned currents in the Venus plasma mantle
Plasma waves, observed above the dayside Venus ionosphere by the Pioneer Venus Orbiter (PVO) plasma wave instrument, have been attributed to whistler mode waves, lower hybrid waves, or ion acoustic

Initial Pioneer Venus Magnetic Field Results: Dayside Observations
TLDR
Observations by the Pioneer Venus mangnetometer in the sunlit ionosphere reveal a dynamic ionosphere, very responsive to external solar-wind conditions, and indicates that the solar wind plays a significant role in the physics of the Venus ionosphere.
Initial Observations of the Pioneer Venus Orbiter Solar Wind Plasma Experiment
Initial results of observations of the solar wind interaction with Venus indicate that Venus has a well-defined, strong, standing bow shock wave. Downstream from the shock, an ionosheath is observed
Electron Temperatures and Densities in the Venus Ionosphere: Pioneer Venus Orbiter Electron Temperature Probe Results
TLDR
Elevated temperatutres observed at times of low solar wind flux exhibit height profiles that are consistent with a model in which less than 5 percent of the solar wind energy is deposited at the ionopause and is conducted downward through an unmagnetized ionosphere to the region below 200 kilomneters where electron cooling to the neutral atmosphere proceeds rapidly.
