Title: X-rays from Orion: Identification and cross correlations of young stars in the Orion nebula
Author: Bergstrom, Erik
Abstract: Recently formed, sun-like stars frequently display large x-ray luminosities. Therefore, x-ray observations provide a powerful means to identify newly formed stars, for the first time. The high spatial resolution of The Chandra X-ray Observatory has given us the ability to identify many stars seen in the x-ray wavelength regime for the first time also. The Orion Nebula is a very well studied region of star formation, and therefore is a good place for initial observations with Chandra. We have analyzed Chandra imaging observations of The Orion Nebula for the purposes of source detection and source identification. The visualizations of the cross correlations in the near infrared and radio have started us on the path toward learning more about the the nature of stars emitting in x-ray, as well as nature of newly forming stars. Within one arc minute around the Becklin-Neugebauer object, fourteen of eighteen or 78 percent of the x-ray sources have near infrared counterparts. Three out of eighteen or 17 percent have known radio counterparts.
