Abstract
KUV 03442+0719 is a ZZ Ceti star originally discovered in 2005. We performed observations for it in 2010, 2011 and 2012. From the three years’ Fourier transform spectra, a total number of 43 pulsation periods are detected. We found out a set of complete quintuplets, five sets of incomplete quintuplets and two sets of incomplete triplets among these periods. They are interpreted as rotational splits of l=2 and l=1 modes. We thus derive a mean rotation period of 6.71±0.11h from the values of splitting spacing. We perform asymptotic analysis to get preliminary identification of the observed pulsation modes.
