Abstract

The high mass X-ray binary 4U 2206+54 has been a very controversial system due to variability in spectral data as well as photometric data. We, at Brigham Young University, have been observing this system in multiple filters with several telescopes. This thesis presents our methods of observations, reductions, and results. It also compares what we have been detecting to other groups looking at the same target in different wavelengths. Furthermore, this thesis discusses some of the peculiarities of 4U 2206+54 and possible theories to explain these phenomena. Based on our photometric observations for the past three years, we believe the period of 4U 2206+54 is 25.1 days. Furthermore, spectral data show an unusual double-peaked Hα feature. We believe the primary star BD +53°2790 is a single star, and that the system is surrounded by a gas and dust shell.
