Constraining asteroid dynamical models using GAIA data

► We plan to use GAIA data to constrain current models on the dynamics of asteroids. ► We will do this by simulating the dynamics as a diffusion plus a Yarkovsky drift. ► Diffusion coefficients will be calculated numerically. ► Yarkovsky drift will take into account YORP forces. ► Optimized solutions will be found by an iterative process.
