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 similar to 1 keV and similar to 10 keV. A coherent feature at similar to 0.643 mHz appeared in the power spectra during the observation.
