Abstract

(Abstract only) We present photometry and spectroscopy of the high amplitude δ Scuti variable star V2455 Cygni. Analysis is presented of the BVRI light curves secured over several years on the 0.9-meter and 0.3-meter telescopes at the Brigham Young University West Mountain Observatory as well as the Orson Pratt Observatory located on the BYU Provo campus. In addition, we present radial velocity measurements and spectrophotometric H-alpha and H-beta measurements secured at the 1.2-meter telescope of the Dominion Astrophysical Observatory in Saanich, British Columbia. These data are used to determine the fundamental properties of this pulsating variable star. We acknowledge the Department of Physics and Astronomy at BYU for continued support of the research work being done at the West Mountain Observatory.
