Oral Presentation
A Deep, Broadband Interferometric Chemical Survey of L1157
Presenter: Andrew Burkhardt (Center for Astrophysics | Harvard & Smithsonian)
Astrophysical shocks substantially alter both the physical conditions and the molecular reservoir in forming protostellar systems, but these effects are not yet well-understood. Nowhere is this seen more clearly than in the prototypical chemically-active shocked outflow, L1157, whose blue-shifted lobe has been the subject of significant single-dish surveys and targeted interferometric observations. Neither approach, however, is able to fully explore how the morphology, excitation, and chemical complexity intertwine to produce the observed emission. Building on previous observations and modeling, we began performing the broadest interferometric molecular survey of L1157 to date to test the predictions from new chemically-complex shock chemistry models by utilizing the wideband capabilities with the SMA. Here, we present the initial results of this survey and the potential of future observations of chemically-active molecular outflows.
