An Analysis of the High Amplitude delta Scuti Star V2455 Cygni
Abstract
The high amplitude delta Scuti (HADS) V2455 Cyg was first noted as a variable star by Wils et al. (2003). They reported a period of 0.0942075 days, with a V amplitude of about 0.44. It has also been suggested that this might be an SX Phe type variable. Since the original discovery paper this star has only received a limited amount of attention. We have collected both spectroscopic and photometric data on this target for the last 10 years. We will present an analysis of the period of V2455 Cyg which suggests a very small companion star. We also examine the temperature and radial velocity over complete pulsation cycles.
