casus/Russia). Our July program is part of a long-term cooperation concerning planet and aeron- omy observations using a Fourier spectrometer able to work between 3 and 12 pm at

However, this profile can be used to obtain more appropriate g-factors to analyse the optical spectra taken in a similar aperture: given the heliocentric velocity of the comet and

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%;
