dc.description.abstractEn | Abstract (2,250 Maximum Characters): The initial mass distribution for exoplanet systems, prior to the onset of planet-planet scattering, has yet to be adequately constrained. Scattering has previously explained a broad range of observed properties, such as large eccentricities, packing, and mean-motion resonances, and hence is an appealing theory. Likewise, a new study has shown that planet-planet scattering is also capable of reproducing the apsidal behavior of observed systems. Scattering is strongly dependent on the initial distribution of planetary masses, which recent results suggest may follow a power law relation. We present the results of numerical simulations of scattering-produced multiple planet systems arising from different initial power law mass distributions, extending down to 1 Earth mass. We test which of these power law distributions most accurately reproduces the observed mass distribution. We find that our simulations are able to reproduce the observed mass distribution, but fail to reproduce the observed eccentricity distribution. We repeat our analysis at increasing initial mutual inclinations, but find that our results do not vary significantly as a result. This suggests that the initial mass distribution is described by a relation more intricate than a global power law, and therefore we explore more complex approaches with which we might constrain the initial mass distribution. | |
