The Dust Environment of Comet 81P/Wild 2

This work is a preliminary study focussed on the dust enviroment of comet 81P/Wild 2. We analyze CCD imaging observations during its last perihelion passage in 2010, and perform a Monte Carlo dust tail analysis in order to retrieve the dust environment that best fits the observations. In the first step of the project we use an isotropic particle emission model run more than 8000 parameters combinations. In the next step to fit the complex structure shown by the comet an anisotropic ejection model is required. We include a rotating nucleus with active areas on it. In addition, we also include the asymmetry in the dust parameters respect to perihelion.
