Abstract

Sulphuric species in protoplanetary disks are still a mystery. The bulk of of the sulphuric abundance has not been observed and the gaseous compounds that have been observed only account for less than 1% of the cosmic abundance. For this project I am working with the Protoplanetary Disk Modelling code called ProDiMo. The aim of this thesis is to investigate in what form sulphur is present in the warm molecular layer of the inner 10 AU of a protoplanetary disc and make spectral predictions of SO2 to determine if this can be observed with JWST. The sulphur chemistry in the warm molecular layer of the inner 10 AU of a protoplanetary disc was determined to be primarily sulphur-oxygen chemistry. Based of spectral predictions with a resolving power of 3000, SO2 is only observable for a disc with a carbon to oxygen ratio smaller than 0.7
