SNe Ia Models and Observations: A Spectroscopist's Point of View

Eddie Baron
University of Oklahoma


I briefly describe the state of empirical determinations of the effectiveness of the use of SNe Ia for cosmology, SNe Ia progenitors, and numerical modeling of the SNe Ia explosion mechanism. From there I describe the status of spectral modeling of SNe Ia and present preliminary results on building a physical "template" that matches observations and can be used to study variations in the explosion mechanism, progenitor age, and composition.
