Stellar Track and Radiance Simulation (STARS)

ExoAnalytic Solutions proposes to develop a star catalog and in-band irradiance simulation by leveraging our in house star background model called STARS (Stellar Track And Radiance Simulation) v1.0 and the Exo6Sim optical focal plane scene generation simulation. STARS v1.0 uses a stellar spectrum fit to the SWIR point source data in the 2MASS database. Stellar spectra are inferred via a maximum likelihood fit to over 3,000 sample spectra in the Hubble ATLAS9 reference spectra database. To meet the requirements for this solicitation, we will develop an upgraded model called STARS v2.0 that will improve fidelity by expanding the number of databases used, take advantage of stellar spectral type databases, and render extended sources as well as point sources. We will also upgrade our spectral inference and in-band integration as required by the solicitation by identifying and resolving data gaps and including effects such as Doppler shift and interstellar medium extinction to provide the highest fidelity in-band signatures for stellar and non-stellar objects from 0.2 V 15 fYm. Validation of the model will be performed using our telescope observatory, camera and advanced algorithms and software tools. Architecture for integration into MDA simulations such as FLITES will also be developed.
