Terrestrial planet formation in low-mass disks: dependence with initial conditions

TL;DR

This study investigates how initial conditions derived from a semi-analytical model influence terrestrial planet formation in low-mass disks, showing that results are robust against variations in initial embryo and planetesimal distributions.

Contribution

It introduces a semi-analytical approach to set initial conditions for N-body simulations, improving upon previous ad hoc methods in planet formation studies.

Findings

Planetary system outcomes are insensitive to initial embryo and planetesimal distributions.

Results are consistent with previous studies despite improved initial conditions.

Abstract

In general, most of the studies of terrestrial-type planet formation typically use ad hoc initial conditions. In this work we improved the initial conditions described in Ronco & de El\'ia (2014) starting with a semi-analytical model wich simulates the evolution of the protoplanetary disk during the gas phase. The results of the semi-analytical model are then used as initial conditions for the N-body simulations. We show that the planetary systems considered are not sensitive to the particular initial distribution of embryos and planetesimals and thus, the results are globally similar to those found in the previous work.
