Workshop on Astrochemistry and radiative transfer

In this workshop we will learn about the astrochemistry package KROME (https://www.kromepackage.org/). We start by downloading the package and making ourselves familiar with the basic functionality. All steps are accompanied by actual exercises which allow us to get a deeper insight into the code. After familiarising ourselves with the code, we will learn the basic syntax of the KROME package and how one can design chemical networks for any user-specific problem. As a next step in the workshop, we will use KROME for actual applications exploring features like temperature calculations next to the calculation of chemical species. We will analyse the output of these first astrochemical simulations to obtain a deeper understanding of the code. The tutorial we will thus provide examples which show how to use full the flexibility of KROME to calculate the thermochemical evolution of astrophysical gases like the interstellar medium. Towards the end of the workshop, we will in a second part briefly explore the radiative transfer code RADMC-3D (https://www.ita.uni-heidelberg.de/~dullemond/software/radmc-3d/). We will create some synthetic emission spectra of the CO molecule and learn basic ways how to investigate line spectra.
