Impact of growing planets on the evolution of protoplanetary disks

The protoplanetary disk (PPD) is a complex structure. It is the birth place of protoplanetary systems. The interaction of growing planets and its surrounding PPD is also complex and not fully understand by now. The many different physical processes going on in the PPD over its life time, like accretion, outbursts, planet formation, etc. impact its evolution and structure. The evolution of such a PPD with a growing planet, implemented as a sink term, is simulated by the TAPIR code.  It is an 1+1D implicit code. Due to the fact that TAPIR is an implicit code the time steps are not restricted by the CFL-conditions, therefore it is able to simulate over the whole lifetime of a PPD and examine the evolutionary behaviour of the protoplanetary disk and the influence of a forming protoplanet on it. The results show the gap formation due to mass accretion onto the planet and impact of this sink term on the total disk mass, disk lifetime and accretion rat onto the star. Also the impact of accretion bursts on the accretion rate of the planet is discussed. If the planet is placed in the dead zone the presence of outbursts leads to a quite faster planet growth since the bursts rearranges the disk structure.
