Determining the Radial Location of the X-ray Emitting Zones of Spica

Abstract

Although it is well known that O and B type stars are X-ray emitters, the mechanism driving this process is not entirely understood. Knowing the radial location of the X-ray emission is key to understanding which models of X-ray emission are correct. In this project, several photospheric models were analyzed to determine which should be used and reconciled discrepancies within the model with observational data of the B-type star, Spica.
