Science Yield Modeling with EXOSIMS

Zodiacal Light Module • Computes local and exozodiacal light levels for each target system Background Sources Module • Provides density of background for target stars • Used in post processing to determine false alarms Planet Physical Model Module • Models light emitted or reflected in wavelengths of interest • Generates synthetic spectra or band photometry Target List Module • Generates list of target stars (based on input modules) • Or list of pre-determined targets (e.g., stars with planets determined via radial velocity measurement) Simulated Universe Module • Creates synthetic universe of systems in target list • Propagates planet position and velocity vectors in time Survey Simulation Module • Performs specific simulation • Returns mission timeline – list of observations and outcomes • Encodes final state of simulated universe and observatory Survey Ensemble Module • Runs multiple survey simulations Planet Population Module Science Yield Modeling with EXOSIMS Daniel Garrett1, Dmitry Savransky1, Rhonda Morgan2, and Patrick Lowrance2 1Sibley School of Mechanical and Aerospace Engineering, Cornell University, Ithaca, NY 2NASA Jet Propulsion Laboratory, Pasadena, CA
