Autor: Huang, Zhenguang, Toth, Gabor, Gombosi, Tamas I., Combi, Michael R., Jia, Xianzhe, Shou, Yinsi, Tenishev, Valeriy, Altwegg, Kathrin, Rubin, Martin

The interaction between a Coronal Mass Ejection (CME) and a comet has been observed several times by in-situ observations from the Rosetta Plasma Consortium (RPC), which is designed to investigate the cometary magnetosphere of comet 67P/Churyumov-Ger

ESA's Rosetta spacecraft at comet 67P/Churyumov-Gerasimenko (67P) was the first mission that accompanied a comet over a substantial fraction of its orbit. On board was the ROSINA mass spectrometer suite to measure the local densities of the volatile

Magnetohydrodynamic with Adaptively Embedded Particle-in-Cell model: MHD-AEPIC

Autor: Shou, Yinsi, Tenishev, Valeriy, Chen, Yuxi, Toth, Gabor, Ganushkina, Natalia

Space plasma simulations have seen an increase in the use of magnetohydrodynamic (MHD) with embedded Particle-in-Cell (PIC) models. This combined MHD-EPIC algorithm simulates some regions of interest using the kinetic PIC method while employing the M

Report

The Surface Distributions of the Production of the Major Volatile Species, H2O, CO2, CO and O2, from the Nucleus of Comet 67P/Churyumov-Gerasimenko throughout the Rosetta Mission as Measured by the ROSINA Double Focusing Mass Spectrometer

The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) suite of instruments operated throughout the over two years of the Rosetta mission operations in the vicinity of comet 67P/Churyumov-Gerasimenko. It measured gas densities and com

Report

A comparison between the two lobes of comet 67P/Churyumov-Gerasimenko based on D/H ratios in H2O measured with the Rosetta/ROSINA DFMS

Autor: Schroeder I, Isaac R. H. G., Altwegg, Kathrin, Balsiger, Hans, Berthelier, Jean-Jacques, Combi, Michael R., De Keyser, Johan, Fiethe, Björn, Fuselier, Stephen A., Gombosi, Tamas I., Hansen, Kenneth C., Rubin, Martin, Shou, Yinsi, Tenishev, Valeriy M., Sémon, Thierry, Wampfler, Susanne F., Wurz, Peter

The nucleus of the Jupiter-family comet 67P/Churyumov-Gerasimenko was discovered to be bi-lobate in shape when the European Space Agency spacecraft Rosetta first approached it in July 2014. The bi-lobate structure of the cometary nucleus has led to m
