Abstract

The photoelectricV observations of the δ Scuti star 59 Aur have been analysed using the techniques of periodogram analysis and least-squares solutions. The fundamental mode is found to be more prominent than the first overtone in the pulsation of 59 Aur. The period ratio of the first overtone to the fundamental (i.e.,P 1/P 0=0.748) indicates that the star pulsates in the radial mode. The absolute magnitude, effective temperature and mass of the star are derived to be 1 m. 22, 7300 K and 2.0M ⊙, respectively. No variations exceeding±0 m. 01 about the mean values ofB-V andU-B colours have been found during a pulsation cycle.
