Atmospheric Escape Rates from Mars - If it Orbited an Old M-Dwarf Star
David A. Brain, Ofer Cohen, Thomas E. Cravens +35
Atmospheric escape is an important process that influences the evolution of planetary atmospheres. A variety of physical mechanisms can contribute to escape from an atmosphere, inc…
Galactic Cosmic Rays at Mars and Venus: Temporal Variations from Hours to Decades Measured as the Background Signal of Onboard Micro-Channel Plates
Yoshifumi Futaana, Manabu Shimoyama, Martin Wieser +8
A Micro-Channel Plate (MCP) is a widely used component for counting particles in space. Using the background counts of MCPs on Mars Express and Venus Express orbiters operated over…
Transit Ly- signatures of terrestrial planets in the habitable zones of M dwarfs
K. G. Kislyakova, M. Holmström, P. Odert +6
We modeled the transit signatures in the Lya line of a putative Earth-sized planet orbiting in the HZ of the M dwarf GJ436. We estimated the transit depth in the Lya line for an ex…
Stellar wind interaction and pick-up ion escape of the Kepler-11 "super-Earths"
K. G. Kislyakova, C. P. Johnstone, P. Odert +6
We study the interactions between stellar wind and the extended hydrogen-dominated upper atmospheres of planets and the resulting escape of planetary pick-up ions from the 5 "super…
Extremely high reflection of solar wind protons as neutral hydrogen atoms from regolith in space
Martin Wieser, Stas Barabash, Yoshifumi Futaana +7
We report on measurements of extremely high reflection rates of solar wind particles from regolith-covered lunar surfaces. Measurements by the Sub-keV Atom Reflecting Analyzer (SAR…
Studying the Lunar-Solar Wind Interaction with the SARA Experiment aboard the Indian Lunar Mission Chandrayaan-1
Anil Bhardwaj, Stas Barabash, M. B. Dhanya +7
The first Indian lunar mission Chandrayaan-1 was launched on 22 October 2008. The Sub-keV Atom Reflecting Analyzer (SARA) instrument onboard Chandrayaan-1 consists of an energetic…
