But Zahnle, an expert
on atmospheric escape of gases, agrees with the main thrust of the study: Right now, dust storms are helping to bleed Mars dry.
This idea has been suggested before and there has been some circumstantial evidence
for atmospheric escape, but this discovery lends the first evidence in direct support.
The simulations illustrated that ancient stellar wind could cause the rate
of atmospheric escape to be far greater than losses produced by the current solar wind that reaches the magnetosphere of Earth.
«Our results indicate that
atmospheric escape may play an important role in the evolution of these planets,» summarises Julien de Wit, from MIT, USA, co-author of the study.
I am also interested in the physics of
atmospheric escape, stellar coronal mass ejections, planet - finding, and statistics.
