The impact of initial density profile on protoplanetary disc evolution simulation

TL;DR

This paper investigates how the initial density profile, specifically a power law, influences the evolution and stability of protoplanetary discs in simulations, revealing that the density profile significantly affects disc instability.

Contribution

It demonstrates that the initial power law density profile causes disc instability, highlighting the importance of initial conditions in protoplanetary disc simulations.

Findings

Disc instability occurs only with a power law density profile.

The instability is influenced by the power index of the profile.

Initial density profile has a large impact on disc evolution.

Abstract

In the simulation of protoplanetary disc with a power law density profile a disc instability is detected. The instability arises only with a power law profile and is affected by power index. Thus the impact of initial density profile is large within the employed numerical model.
