| 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. |
