Scientific paper

We investigate the expected composition of planetesimals around stars with varying C/O ratios, under a variety of circumstellar nebula conditions. These condensate compositions can be used to estimate the amount of heavy element and volatile enrichment in giant planets accreting material from beyond the snow line in these systems. In systems with sub-solar C/O planetesimals will be rich in H2O ice compared with the solar system, while systems with higher C/O will have less H2O and more silicate and metal, as well as CO in solid form if cold enough.
