Suzaku observations of the peculiar cataclysmic variable FS Aurigae
Abstract
FS Aur is a peculiar cataclysmic variable containing a magnetic and freely precessing white dwarf. The system is known to exhibit three very coherent periodic signals in the optical photometric and spectroscopic data. The periods of these signals are the orbital period, the period of precession of the white dwarf and the beat period between former two. The previous X-ray observations made with Chandra and Swift, also revealed the presence of strong modulation with the orbital period. However, the existence of the precession and beat period signals in X-rays is not conclusive owing to insufficient data. Here we present the longest and the most sensitive X-ray observations of FS Aur made with the Suzaku observatory in 2013. We use these data to analyse temporal and spectral properties of X-ray emission from the object.
