Abstract
Using archival ASCA observations of TT Arietis, X-ray energy spectra and power spectra of the intensity time series are presented for the first time. The energy spectra are well-fitted by a two continuum plasma emission model with temperatures ∼1 keV and ∼10 keV. A coherent feature at ∼0.643 mHz appeared in the power spectra during the observation.
