Sublimation Kinetics of Co2 Ice and Evolution of the Martian Polar Caps
Introduction: The martian polar caps are in majority composed of CO2 ice [1-3]. Early modeling of the polar caps suggested that they were in equilibrium with the ~6 mbar CO2 atmosphere [2], and various observations have shown a ciclicity of growth and retreat, following martian seasons [4]. However, other studies show that CO2 ice constitutes only a thin veneer on the surface of a probably much...
متن کاملObservation of Martian Seasonal Caps: Dimensions, density, mass, inter annual variations
Introduction: For this investigation we have used neutron spectroscopy data gathered with HEND/GRS instrument onboard Mars Odyssey. Starting from 2002 this mission passed through primary and several extended phases accumulating enormous data volume. During this mission one has been proved that orbital mapping of neutron flux from martian surface (instruments HEND, NS and GRS) is powerful method...

متن کاملIce Sheet Modelling and Applications to Greenland, Antarctica and the Martian Polar Ice Caps
Ice sheets, ice shelves, ice caps and glaciers are active, dynamic components of the climate system of the Earth, and they deserve the same scientific attention as the atmosphere and the oceans. Since the late 1970s, numerical modelling has become established as an important technique for the understanding of ice dynamics. Ice sheet models are particularly relevant for predicting their possible...
متن کاملThe Shape of Pulsar Polar Caps
Rotation distorts the vacuum magnetic field of a pulsar from that of a simple dipole. The effect is particularly strong close to the light cylinder, but also affects the field close to the stellar surface. We find the shape and locus of the field lines which just close at the light cylinder. Their footpoints define the pulsar polar cap. We find this cap is asymmetric and distorted. We also find...
