Photometric study of comet 67P/Churyumov-Gerasimenko as seen by VIRTIS-H onboard Rosetta

Résumé

In this study we present an analysis of the large dataset from H channel of VIRTIS (Visible Infrared Thermal Imaging Spectrometer) onboard ESA's Rosetta spacecraft.We focus on photometric properties of the nucleus since there are many different observation geometries and illumination conditions available. Variations of the signal with phase are reproduced with a Lommel-Seeliger model. This allows to retrieve phase function and then, by fitting the data, the single scattering albedo and asymmetry parameter for every wavelength.
