Assignment and rotational analysis of new absorption bands of carbon dioxide isotopologues in Venus spectra

Vandaele, A. C.; Robert, S.; Wilquet, V. +7 more

We present absorption bands of carbon dioxide isotopologues, detected by the Solar Occultation for the Infrared Range (SOIR) instrument on board the Venus Express Satellite. The SOIR instrument combines an echelle spectrometer and an Acousto-Optical Tunable Filter (AOTF) for order selection. It performs solar occultation measurements in the Venus …

Imaging polarimetry of cometary dust: different comets and phase angles

Levasseur-Regourd, A. C.; Hadamcik, E.

Polarimetric observations of the light scattered by dust in cometary comae have been carried out at Pic-du-Midi Observatory and at Haute-Provence Observatory (France) between 1990 and 2001. The whole coma polarization can easily be inferred from integration of the fluxes on the aperture. Maps are obtained for seven comets by CCD imaging polarimetr…
