TL;DR: In situ chemical analysis of Titan's aerosols by pyrolysis at 600 °C shows that the aerosol particles include a solid organic refractory core, and their presence demonstrates that carbon and nitrogen are in the aerosols.
Journal ArticleDOI
Mars atmospheric escape and evolution; interaction with the solar wind
TL;DR: In this article, a simplified approach of non-thermal escape was developed, treating in a specific way the different kinds of escape (photochemical escape, ion sputtering, ion escape and ionospheric outflow).
Journal ArticleDOI
Geochemistry of Carbonates on Mars: Implications for Climate History and Nature of Aqueous Environments
Paul B. Niles,David C. Catling,Gilles Berger,Eric Chassefière,Bethany L. Ehlmann,Joseph R. Michalski,Joseph R. Michalski,Richard V. Morris,Steven W. Ruff,Brad Sutter +9 more
TL;DR: Carbonate minerals have now been identified in a wide range of localities on Mars as well as in several martian meteorites as mentioned in this paper, and the presence of carbonates along with evidence for active carbonate precipitation suggests that a global acidic chemistry is unlikely and a more complex relationship between acidity and carbonate formation.
Journal ArticleDOI
Titan's Geometric Albedo: Role of the Fractal Structure of the Aerosols
TL;DR: In this paper, the optical behavior of Titan's aerosols is modeled assuming that each monomer radiates a dipole field in response to the incident radiation including the radiated fields of all the other elements in the aggregate.
Journal ArticleDOI
Fractal aggregates in Titan's atmosphere
TL;DR: In this article, a fractal model was used to estimate the formation altitude of photochemical aerosols in Titan's atmosphere and the vertical profile of the effective radius of aggregates was calculated as a function of the visible optical depth derived from Voyager imaging.
