Comparison of cloud models for Brown Dwarfs

TL;DR

This paper compares various dust cloud models used in brown dwarf and giant planet atmospheres to evaluate uncertainties and differences in spectral predictions.

Contribution

It provides a systematic comparison of cloud models, highlighting how different assumptions affect dust properties and spectral energy distributions in substellar atmospheres.

Findings

Model results for dust quantities vary significantly with assumptions.

Spectral energy distributions differ notably between models.

The study enhances transparency in theoretical brown dwarf modeling.

Abstract

A test case comparison is presented for different dust cloud model approaches applied in brown dwarfs and giant gas planets. We aim to achieve more transparency in evaluating the uncertainty inherent to theoretical modelling. We show in how far model results for characteristic dust quantities vary due to different assumptions. We also demonstrate differences in the spectral energy distributions resulting from our individual cloud modelling in 1D substellar atmosphere simulations
