Description
Planet formation occurs in accretion discs that surround young stars. Using DiRAC we have been able to characterize the dynamics of these discs throughout the various stages of their evolution from massive, self-gravity dominated discs through to their eventual dispersal through photo-evaporation. I will present new insights that have arisen out of these simulations on topics including turbulence, stability and fragmentation of both gas in the self-gravitating phase; along with the implications for planet formation. I will also discuss new results on the conditions under which interactions with external stars can trigger fragmentation and the role that nearby massive stars play in disc dispersal.
