Abstract

We measured the photometric flux of the cataclysmic variable TT Arietis (BD+14 341) using the MOST space telescope. Periodic oscillations of the flux reveal the photometric period as well as other features of this binary system. We applied a Discrete Fourier Transform (DFT) on a reduced data set to retrieve the frequencies of TT Arietis. The analysis of the system revealed a primary photometric period of 3.19 hours. Though the MOST data has a high cadence of 52.8 seconds, a fine structure of the accretion disk is not obvious.
