Exoplanetary Atmospheres—Chemistry, Formation Conditions, and Habitability

Characterizing the atmospheres of extrasolar planets is the new frontier in exoplanetary science. The last two decades of exoplanet discoveries have revealed that exoplanets are very common and extremely diverse in their orbital and bulk properties. We now enter a new era as we begin to investigate the chemical diversity of exoplanets, their atmospheric and interior processes, and their formati...

Chemistry of Silicate Atmospheres of Evaporating Super- Earths

Non-equilibrium chemistry in the atmospheres of brown dwarfs

Carbon monoxide and ammonia have been detected in the spectrum of Gl 229B at abundances that differ substantially from those obtained from chemical equilibrium. Vertical mixing in the atmosphere is a mechanism that can drive slowly reacting species out of chemical equilibrium. We explore the effects of vertical mixing as a function of mixing efficiency and effective temperature on the chemical ...

High-Power Laser-Plasma Chemistry in Planetary Atmospheres

Currently generally accepted opinion considering Earth’s early atmosphere as a mildly reduced gas mixture of molecular gases represents a crucial difficulty for the classical Miller's experiments carried out originally in a strongly reducing gaseous mixture. In the weakly reducing environment they give a poor yield of amino acids and other compounds of relevance to the chemical evolution. In ou...
