Signatures of X-ray dominated chemistry in the spectra of exoplanetary atmospheres
Daniele Locci, Giambattista Aresu, Antonino Petralia +3
High-energy radiation from stars impacts planetary atmospheres deeply affecting their chemistry, providing departures from chemical equilibrium. While the upper atmospheric layers…
Extreme ultraviolet and X-ray driven photochemistry of gaseous exoplanets
Daniele Locci, Antonino Petralia, Giuseppina Micela +3
The interaction of exoplanets with their host stars causes a vast diversity in bulk and atmospheric compositions, and physical and chemical conditions. Stellar radiation, especiall…
A systematic study of \ce{CO2} planetary atmospheres and their link to the stellar environment
A. Petralia, E. Alei, G. Aresu +5
The Milky Way Galaxy is literally teeming with exoplanets; thousands of planets have been discovered, with thousands more planet candidates identified. Terrestrial-like planets are…
Synthesis of complex organic molecules in soft x-ray irradiated ices
A. Ciaravella, A. Jiménez-Escobar, C. Cecchi-Pestellini +4
We study the chemical evolution of H2O:CO:NH3 ice mixtures irradiated with soft X-rays, in the range 250-1250 eV. We identify many nitrogen-bearing molecules such as e.g., OCN-, NH…
Photo-evaporation of close-in gas giants orbiting around G and M stars
Daniele Locci, Cesare Cecchi Pestellini, Giuseppina Micela
X-rays and extreme ultraviolet radiation impacting on a gas produce a variety of effects that, depending on the electron content, may provide a significant heating of the illuminat…
Photo-desorption of H2O:CO:NH3 circumstellar ice analogs: Gas-phase enrichment
A. Jimenez-Escobar, A. Ciaravella, C. Cecchi-Pestellini +4
We study the photo-desorption occurring in HO:CO:NH ice mixtures irradiated with monochromatic (550 and 900 eV) and broad band (250--1250 eV) soft X-rays generated at the N…
