The temporal evolution of exposed water ice-rich areas on the surface of 67P/Churyumov-Gerasimenko: thermal analysis
Résumé
We perform a thermal analysis of three icy patches on the comet 67P/Churyumov-Gerasimenko in order to derive the total mass of water ice sublimated, and the thickness of the ice-rich layer. We obtained an upper limit of 200 kg per square meter. The mass sublimated expressed as thickness of a pure water ice layer is about 20 cm.
