Surface Chemistry Update of the KOSMA-{τ} PDR Code
Abstract
Numerical PDR codes are commonly limited to a pure gas-phase chemistry, with the exception of the Formation of H2. For most species this is reasonably well assumption given the usual physical conditions in photondominated regions. However, for some species, such as H2O, O2, or CH3OH, the pure gas-phase computation is insufficient.
We present a recent update of the chemistry included in the Cologne PDR code KOSMA-{τ}, where we included a network of grain surface reactions into our chemical computation scheme.- Publication:
