The accretion of pebbles on planetary cores has been widely studied in recentyears and is found to be a highly effective mechanism for planetary growth.While most studies assume planetary cores as an initial condition in theirsimulation, the question how, where and when these cores form is oftenneglected. We study the impact of pebble accretion during the formation phaseand subsequent evolution of planetary embryos in the early stages ofcircumstellar disk evolution. In doing so we aim to quantify the timescales andlocal dependency of planetary embryo formation, based on the solid evolution ofthe disk. We connect a one dimensional two population model for solid evolutionand pebble flux regulated planetesimal formation to the N-body code LIPAD. Inour study we focus on the growth of planetesimals with an initial size of 100km in diameter by planetesimal collisions and pebble accretion for the first 1million years of a viscously evolving disk. We compare 18 different N-bodysimulations in which we vary the total planetesimal mass after 1 million years,the surface density profile of the planetesimal disk, the radial pebble fluxand the possibility of pebble accretion. Pebble accretion leads to theformation of fewer, but substantially more massive embryos. The area ofpossible embryo formation is weakly influenced by the accretion of pebbles andthe innermost embryos tend to form slightly earlier compared to the simulationsin which pebble accretion is neglected. Pebble accretion strongly enhances theformation of super earths in the terrestrial planet region, but it does notenhance the formation of embryos at larger distances.
