# Homogeneous model for the TRAPPIST-1e planet with an icy layer

@article{Gevorgyan2021HomogeneousMF, title={Homogeneous model for the TRAPPIST-1e planet with an icy layer}, author={Yeva Gevorgyan}, journal={Astronomy and Astrophysics}, year={2021} }

In this work we investigate whether a multi-layered planet can be approximated as a homogeneous planet. The answer is positive for bodies with an icy crust if we employ the so-called Sundberg-Cooper rheology to model the homogeneous body. Our results compare well with recent results employing a multi-layered model for the TRAPPIST-1e planet.
