Composition-dependent outgassing of comet 67P/Churyumov-Gerasimenko from ROSINA/DFMS. Implications for nucleus heterogeneity?

The aim of this paper is to present high-resolution measure- ments from the Double Focusing Mass Spectrometer (DFMS), part of the Rosetta Orbiter Sensor for Ion and Neutral

Sub-region b has a value of 9.59 (a value seen for smooth sub-regions) while the value for sub-region a is 16.61 placing this sub- region at a roughness level similar to rougher

The properties expected for small collisional rubble piles should be compared to those of comet 67P; (1) a low bulk density ρ bulk = 535 ± 35 kg m −3 and high porosity of ∼70%;

This shows that only a particular family of dust was the source of the observed OSIRIS dust bursts, and that the dust size correction by a factor 5 ± 1 provides a simple and

In this thesis, I present the design and implementation of a novel cantilever probe holder that is capable of tapping mode operation.. The probe holder is implemented

Une solution pour augmenter la dur´ee d’interrogation est de pi´eger les atomes, avec un pi`ege dipolaire, un pi`ege magn´etique, ou encore un pi`ege ´electrique dans le cas des ions

through. A final snap through occurs when the device reaches point D, where the nPGM possesses four kinks and has just entered region II behavior. After point D the

These computed values were chosen correspond to the sensor input and motor output of the BiOM. Height, z acceleration, shank pitch, shank pitch velocity,
