Venus has no significant internal magnetic field, which allows the solar wind to interact directly with its atmosphere2,3. A field is induced in this interaction, which partially shields the atmosphere, but we have no knowledge of how effective that shield is at solar minimum. (Our current knowledge of the solar wind interaction with Venus is derived from measurements at solar maximum.) The bow shock is close to the planet, meaning that it is possible that some solar wind could be absorbed by… 

Disappearing induced magnetosphere at Venus: Implications for close‐in exoplanets

The solar wind interaction with a planetary atmosphere produces a magnetosphere‐like structure near the planet whether or not the planet has an intrinsic global magnetic field. In the case of planets

Oxygen Loss from Venus and the Influence of Extreme Solar Wind Conditions

The purpose of this dissertation is to expand our understanding of oxygen ion escape to space from Venus and its dependence on extreme solar wind conditions found during interplanetary coronal mass

The loss of ions from Venus through the plasma wake

Measurements of the atmosphere of Venus show that the dominant escaping ions are O+, He+ and H+.

Solar Wind Interaction and Impact on the Venus Atmosphere

Venus has intrigued planetary scientists for decades because of its huge contrasts to Earth, in spite of its nickname of “Earth’s Twin”. Its invisible upper atmosphere and space environment are also

Giant vortices lead to ion escape from Venus and re‐distribution of plasma in the ionosphere

The interaction of the solar wind with Venus has a significant influence on the evolution of its atmosphere. Due to the lack of an intrinsic planetary magnetic field, there is direct contact between

Solar energetic particle interactions with the Venusian atmosphere

In the context of planetary space weather, we estimate the ion production rates in the Venusian atmosphere due to the interactions of solar energetic particles (SEPs) with gas. The assumed concept

Measurements of the ion escape rates from Venus for solar minimum

[1] We report the first direct measurements of the Venusian atmospheric erosion rate due to the interaction with the solar wind. The erosion through the ion escape is determined during the period of

Mirror‐mode‐like structures in Venus' induced magnetosphere

[1] The solar wind interaction with Venus creates an induced magnetosphere around the planet. It is shown that within the space bound by Venus' bow shock and ionopause, there is a rich occurrence of

The Venus Express observation of Venus’ induced magnetosphere boundary at solar maximum

The Venusian plasma environment is divided into two distinct regions by the induced magnetosphere boundary (IMB): the domain of solar wind protons and the domain of local planetary ions. Previous



Solar and interplanetary control of the location of the Venus bow shock

The Venus bow shock location has been measured at nearly 2000 shock crossings, and its dependence on solar EUV, solar wind conditions, and the interplanetary magnetic field determined. The shock

The solar wind interaction with Venus - Pioneer Venus observations of bow shock location and structure

Pioneer Venus observations are used in conducting a study of the location and structure of the Venus bow shock. The trace of the shock in the solar wind aberrated terminator plane is nearly circular

The solar cycle dependence of the location and shape of the Venus bow shock

From initial Pioneer Venus observations during the maximum of solar cycle 21 it was evident that the position of the Venus bow shock varies with solar activity. The bow shock radius in the terminator

Solar wind flow about the terrestrial planets: 2. Comparison with gas dynamic theory and implications for solar‐planetary interactions

This study utilizes gas dynamic calculations in conjunction with observational bow shock models to investigate the solar wind flow patterns about the terrestrial planets. Average dayside bow shock

The magnetic barrier at Venus

The magnetic barrier at Venus is a region within which the magnetic pressure dominates all other pressure contributions. The barrier is formed in the inner region of the dayside magnetosheath to

Plasma near Venus from the Venera 9 and 10 wide-angle analyzer data

Preliminary results of ion and electron plasma measurements near Venus are presented and discussed. The data were obtained with wide-angle plasma analyzers carried on the Venera 9 and 10 spacecraft.

The solar wind interaction with Venus

This paper assesses our current understanding of the solar wind interaction with Venus in light of developments since the last major reviews were published in 1983. Suggestions for making further
