Abstract:In regions of star formation, astrophysical shocks have been found to be both common and influential on the molecular make-up of the surrounding material. The formation of complex organic molecules (COMs) in the interstellar medium relies on interplay between gas-phase and grain-surface physical and chemical processes, including shock-induced non-thermal desorption of COMs formed on the grain. We will utilize the gas-grain chemical network model textsc{nautilus}, coupled with the inclusion of a high-temperature network and a parametric shock model, with the inclusion of collisional dust heating and sputtering processes from gas-phase particles, in order to study the effects shocks have on the chemical complexity of a prototypical shocked outflow over a range of chemically-relevant timescales. Here, we will present the effectiveness of using chemical tracers to determine the presence of a shock long after it has passed, as well as the prominence of post-shock gas-phase formation and destruction of shock-tracing molecules.
