Model-Observation Comparisons of Electron Number Densities in the Coma of 67P/Churyumov–Gerasimenko During 2015 January

The coordinated campaign of roughly parallel observations with Rosetta began in the 2013 observing season, with approximately monthly imaging with the ESO 8 m Very Large Telescope

We report the detection of argon and its relation to the water abundance in the Jupiter family comet 67P/Churyumov-Gerasimenko by in situ measurement of the Rosetta Orbiter

We modeled the isotopic compositions of 67P/C-G krypton and xenon as the result of mixing between an exotic component rich in s-process isotopes and labeled here as X with a

This study uses data from Rosetta’s OSIRIS camera system and presents observations of the inner coma of 67P/Churyumov-Gerasimenko acquired with narrow band filters centered

G/R ratio profile for 67P from 10 to 10 4 km for a line of sight crossing the projected cometocentric distance according to different levels of solar activity: for medium solar

First, we perform a cross-calibration of RPC-MIP plasma density and RPC-LAP spacecraft potential variations using a simple spacecraft charg- ing model to obtain plasma

(i) We measured the average spectral slope of the grains for each set of images obtaining the total average value of 12.9 ± 0.2 per cent / 100 nm in the range [480–649] nm and 7.3 ±

Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov–Gerasimenko measured with the COmetary Secondary
