Regional study of Europa's photometry

Résumé

Studying Europa's surface from a photometric point of view gives us insight on its physical state. We studied 20 areas scattered across the surface and estimated their photometric behavior using the Hapke model and a Bayesian framework. We have found that most of them were consistent with the bright backscattering behavior of Europa, already observed at a global scale, indicating the presence of grains maturated by space weathering. However, we have identified areas showing a narrow forward scattering possibly indicating the presence of fresh deposits that could be linked to recent cryovolcanism or jets. We have also found rough areas near the equator on the leading side in agreement with the possible presence of penitentes in this region.
