A Preliminary Asteroseismic Investigation of 4 CVn
Abstract
By means of the structure and evolution code provided by Luo Guo-Quan (1991, 1997) as well as the pulsation computation program offered by Li Yan (1990, 1994), a test of the asteroseismology of the Delta Sct star 4 CVn is presented here. The observed parameters are adopted from Zhou Ai-Ying et al. (1997), Breger (1990a) and Breger et al. (1990a). Three steps are involved in the calculations. The zero age main sequence model was first established, then the evolution track was built. Last, by choosing a close phase from the comparison between the observed luminosity and effective temperature and that of the calculated track with a certain mass, one lets the star pulsate starting from that point.
