Fifty Years of TT Arietis

摘要

Results of photometric observations of the permanent negative superhumper TT An in 1961/62 and 1966 are presented. Together with data from the literature they are used to discuss the negative superhump amplitudes A(nSH) and the amplitudes A(beat) of the modulation with the beat period P-beat. Both amplitudes are shown to vary considerably from one season to another. Three correlations are found: (1) between A(nSH) and A(beat), (2) between A(nsH) and P-nsH, and (3) between A(beat) and P-beat.
