Theory and simulation of spectral line broadening by exoplanetary atmospheric haze
Z. Felfli, T. Karman, V. Kharchenko +3
Atmospheric haze is the leading candidate for the flattening of expolanetary spectra, as it's also an important source of opacity in the atmospheres of solar system planets, satell…
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…
Precipitation of Energetic Neutral Atoms and Induced Non-Thermal Escape Fluxes from the Martian Atmosphere
Nicholas Lewkow, Vasili Kharchenko
The precipitation of energetic neutral atoms, produced through charge exchange collisions between solar wind ions and thermal atmospheric gases, is investigated for the Martian atm…
Solar wind charge exchange X-ray emission from Mars Model and data comparison
Dimitra Koutroumpa, Ronan Modolo, Gerard Chanteur +3
Aims. We study the soft X-ray emission induced by charge exchange (CX) collisions between solar-wind, highly charged ions and neutral atoms of the Martian exosphere. Methods. A 3D…
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…
X-rays from solar system objects
Anil Bhardwaj, Ronald F. Elsner, G. Randall Gladstone +11
During the last few years our knowledge about the X-ray emission from bodies within the solar system has significantly improved. Several new solar system objects are now known to s…
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+}…
