Can Vesta have a polar cap? Eleonora Ammannito INAF/IFSI - Roma CISAS - Padova CISAS-UPD

2
The model Time-dependent, unidimensional partial differential equations, expressing the conservation of energy (heat diffusion) and mass (gas diffusion), in the general form = density, = flux, Q = source term PDE's are solved numerically in discrete time steps on a discrete grid

3
The initial conditions Seasonal variation of the temperature at different latitudes on the surface of Vesta. It was condidered the equilibrium between the solar irradiance at the Vestas distance from the Sun at each latitude and the thermal emission of the body. Parametri orbitali: Parametri fisici:
