| My primary goal is to reproduce the formation of a terrestrial-like planetary system with planar n-body simulations. The first pioneering numerical studies were conducted by Cox & Lewis in 1980, when the evolution of a disk containing 100 protoplanets around a solar mass star was studied for approximately 105 years. I would like to scrutinize their findings in this study, as they have not been critically examined later. This may be interesting, among other things, because further research may be based on erroneous assumptions later on. Cox & Lewis' primary finding was that the growth of bodies with final masses approaching those of Venus and Earth is possible, moreover, their semimajor axes and eccentricities were also similar to those of Venus and Earth. Their results were primarily determined by the choice of initial conditions. Performing several runs using their initial conditions but solving the exact equations of motion, I refined their findings. From the results of the ongoing research so far, I would like to point out that performing both low- and high-resolution runs did not result in terrestrial-like planetary system. |
