Solar activity variations of the ionospheres of Venus and Mars
… in our understanding of how the ionospheres of Venus and Mars react to solar activity; namely, how the electron density and ion composition respond to changing solar irradiance in the highly variable region above the ionospheric peak. Using remote sensing observations from Venus Express and Mars …

Dynamique et composition des atmosphères supérieures de Mars et Vénus observées par les spectrographes ultraviolets à bord de Mars Express et Vénus Express
Venus has a dense CO2-dominated atmosphere. Above 50 km, the atmospheric circulation is composed of two dominants patterns: the Retrograde Superrotating Zonal (RSZ) circulation up to 65 km and the subsolar to antisolar (SSAS) circulation beyond 120 km. The SSAS is caused by the temperature gradient …

Multi-spectrum retrieval of maps of Venus' surface emissivity in the infrared
… in the infrared from radiance measurements of Venus. Since these data are diagnostic of the chemical composition and grain size of the surface material, they can help to improve knowledge of the planet’s geology. Spectrally resolved images of nightside emissions in the range 1.0-5.1 μm were …
