Elastic and inelastic cross sections for C+CO and C+CO scattering at superthermal energies
Marko Gacesa
We report elastic and inelastic cross sections for fast superthermal C() and C() atoms scattering on CO. The cross sections were computed using q…
O()+CO scattering cross sections at superthermal collision energies for planetary aeronomy
Marko Gacesa, Robert J. Lillis, Kevin J. Zahnle
We report new elastic and inelastic cross sections for O()+CO scattering at collision energies from 0.03 to 5 eV, of major importance to O escape from Mars, Venus, and CO$…
Impacts of Quantum Chemistry Calculations on Exoplanetary Science, Planetary Astronomy, and Astrophysics
Der-you Kao, Marko Gacesa, Renata M. Wentzcovitch +26
Several of NASA missions (TESS, JWST, WFIRST, etc.) and mission concepts (LUVOIR, HabEx, and OST) emphasize the exploration and characterization of exoplanets, and the study of the…
Strange messenger: A new history of hydrogen on Earth, as told by Xenon
Kevin J. Zahnle, Marko Gacesa, David C. Catling
Atmospheric xenon is strongly mass fractionated, the result of a process that apparently continued through the Archean and perhaps beyond. Previous models that explain Xe fractiona…
Non-thermal production and escape of OH from the upper atmosphere of Mars
Marko Gacesa, Nicholas Lewkow, Vasili Kharchenko
We present a theoretical analysis of formation and kinetics of hot OH molecules in the upper atmosphere of Mars produced in reactions of thermal molecular hydrogen and energetic ox…
Non-thermal escape of molecular hydrogen from Mars
Marko Gacesa, Peng Zhang, Vasili Kharchenko
We present a detailed theoretical analysis of a non-thermal escape of molecular hydrogen from Mars induced by collisions with hot atomic oxygen from martian corona. To accurately d…
Polarization of the charge-exchange X-rays induced in the Heliosphere
Marko Gacesa, Hans-Reinhard Müller, Robin Côté +1
We report results of a theoretical investigation of polarization of the X-ray emissions induced in charge-exchange collisions of fully stripped solar wind ions C and O$^{8+}…
