Stellar control on atmospheric carbon chemistry, CO runaway, and organic synthesis on lifeless Earth-like planets
Yoshiaki Endo, Yasuto Watanabe, Kazumi Ozaki
The abundances of atmospheric carbon species--carbon dioxide (CO2), carbon monoxide (CO), and methane (CH4)--exert fundamental controls on the climate, redox state, and prebiotic e…
Behaviors of Martian CO2-driven dry climate system and conditions for atmospheric collapses
Yasuto Watanabe, Eiichi Tajika, Arihiro Kamada
The present Martian climate is characterized by a cold and dry environment with a thin atmosphere of carbon dioxides (CO2). In such conditions, the planetary climate and habitabili…
Controls of Atmospheric Methane on Early Earth and Inhabited Earth-like Terrestrial Exoplanets
Aika Akahori, Yasuto Watanabe, Eiichi Tajika
Methane (CH4) is a primarily biogenic greenhouse gas. As such, it represents an essential biosignature to search for life on exoplanets. Atmospheric CH4 abundance on Earth-like inh…
Relative abundances of CO2, CO, and CH4 in atmospheres of Earth-like lifeless planets
Yasuto Watanabe, Kazumi Ozaki
Carbon is an essential element for life on Earth, and the relative abundances of major carbon species (CO2, CO, and CH4) in the atmosphere exert fundamental controls on planetary c…
