Chemical and Dynamical Processes in the Atmospheres of I. Ancient and Present-Day Earth, II. Jupiter and Galileo Satellite, III. Extrasolar “Hot Jupiters” [PDF]

open access: yes, 2006
When exposed to stellar UV radiation, chemical processes will be governed not only by temperature/pressure but also the spectrum of the incoming dissociative photon flux; the system will approach kinetic, or photochemical, equilibrium, instead of ...

A ring system detected around the Centaur (10199) Chariklo [PDF]

open access: yes, 2014
Hitherto, rings have been found exclusively around the four giant planets in the Solar System1. Rings are natural laboratories in which to study dynamical processes analogous to those that take place during the formation of planetary systems and galaxies.

Abiotic oxygen-dominated atmospheres on terrestrial habitable zone planets [PDF]

open access: yes, 2016
Detection of life on other planets requires identification of biosignatures, i.e., observable planetary properties that robustly indicate the presence of a biosphere. One of the most widely accepted biosignatures for an Earth-like planet is an atmosphere

Cassini observations reveal a regime of zonostrophic macroturbulence on Jupiter [PDF]

open access: yes, 2014
In December 2000, the Cassini fly-by near Jupiter delivered high-resolution images of Jupiter’s clouds over the entire planet in a band between 50°N and 50°S. Three daily-averaged two-dimensional velocity snapshots extracted from these images are used to

The Schumann resonance: A tool for exploring the atmospheric environment and the subsurface of the planets and their satellites [PDF]

open access: yesIcarus, 2008
The propagation of extremely low frequency (ELF) electromagnetic waves and resonance phenomena in the Earth atmosphere has been extensively studied, in relation with ionospheric dynamics, and thunderstorm and lightning activities. A similar investigation can be performed for any other planet and satellite environment, provided this body is wrapped into

Chemistry of Atmospheres: An Introduction to the Chemistry of the Atmospheres of Earth, the Planets and Their Satellites

open access: yesEos, Transactions American Geophysical Union, 1987
The author of this book states that he has attempted to produce a text that will be “intelligible to readers approaching atmospheric chemistry from any scientific discipline.” He proposes to provide the links between atmospheric chemistry and the traditional approaches to physics, chemistry, and biology.

The transmission spectrum of Earth-size transiting planets [PDF]

open access: yes, 2005
International audienceA variety of terrestrial planets with different physical parameters and exotic atmospheres might plausibly exist outside our Solar System, waiting to be detected by the next generation of space-exploration missions.

Magnetically controlled mass loss from extrasolar planets in close orbits [PDF]

open access: yes, 2014
We consider the role magnetic fields play in guiding and controlling mass-loss via evaporative outflows from exoplanets that experience UV irradiation. First we present analytic results that account for planetary and stellar magnetic fields, along with ...

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

The stability of short-period extrasolar giant planets [PDF]

open access: yes, 2008
A three-dimensional coupled thermosphere-ionosphere model for extrasolar giant planets (EXOTIM) has been developed. This is the first such model reported in the literature.
