New gravity field of comet 67P/C-G based on Rosetta's Doppler and optical data
Julien Laurent-Varin, Théo James, Jean-Charles Marty +3
We provide a new gravity field of Comet 67P-C/G up to degree 4. We detect mass heterogeneity in the comet nucleus. The loss of mass is restimated at 0.28\% of the comet's total mas…

HelioCast: heliospheric forecasting based on white-light observations of the solar corona. I. Solar minimum conditions
Victor Réville, Nicolas Poirier, Athanasios Kouloumvakos +8
We present a new 3D MHD heliospheric model for space-weather forecasting driven by boundary conditions defined from white-light observations of the solar corona. The model is based…
