Abstract
The light curves of the totally eclipsing system TT Hya in UBV colours observed by Kulkarni and Abhyankar during 1973-77 have been analysed by Kopal's frequency domain method with slight modification. We find rs (primary) = 0.104 ± 0.005, rg (secondary) = 0.215 ± 0.008 and i = 89° ± 1°. The value of rg obtained in this study is smaller than that determined earlier by Kulkarni and Abhyankar by the method of Russell and Merrill; this confirms the undersized nature of the secondary component. The ultraviolet colour excess of the secondary is also confirmed.
