My group at UNLV has developed several new tools for the study of exoplanet science. These include modules for the REBOUND n-body integrator that incorporate stellar evolution, tides, the Yarkovsky effect, and collisions and fragmentation between uniform and differentiated bodies. In addition, our group has a new, fast interior structure code, MAGRATHEA, to model the internal properties of planets. I will describe these different tools and show some of the interesting results that have come from their application.
