Photometric observations and frequency analysis of the δ Scuti NT Hya
Abstract
NT Hya is a δ Scuti star discovered by Hipparcos. About 2200 observations were acquired with the 30 inch SAAO telescope in the nights of February 2,3 and 4, 2006 in V filter. These data show four pulsation frequencies of the star. Two of them may form a doublet separated by 0.64 c/d (Δf/f = 9%) with similar amplitudes. The period listed in the Hipparcos Catalogue is between the doublet frequencies.
