A Mega-Grid of CMFGEN Model Atmospheres for Rapid Analysis of Stellar Spectra

CMFGEN (Hillier & Miller 1998) is a sophisticated and widely-used nonLTE stellar atmosphere code. It models the full spectrum, and has been used to model OB stars, W-R stars, luminous blue variables, and supernovae. However, it requires the user to have substantial knowledge and experience to run it, and even then a complete analysis of a star can be very difficult and time consuming. Computations and modeling with CMFGEN are greatly eased when suitable initial models are available. To expedite modeling, or to run a quick rudimentary analysis of the stellar spectra, we are undertaking a project to create a mega-grid of pre calculated CMFGEN models which will be available to the general astronomical community via internet. Tools are also being developed to use this database for analysis.
