| 英文摘要 | We present the results of spectroscopy and B, V CCD photometry carried out from 2003 to 2005 of GSC4619-450, a high-amplitude pulsating variable discovered by Zhang et al., [Zhang, X.B., Deng, L., Zhou, X., Xin, Y., 2004. MNRAS, 355, 1369]. From this study, the star is classified as a high-amplitude delta Scuti star. A Fourier analysis based on the B and V photometric data indicates that GSC 4619-450 is a mono-periodic radial pulsator, with a period of 0.13341195 days. From a short time line we find that the pulsating period of this star is increasing rapidly with a rate of 9.1 x 10(-2) s/yr, and is thus suggested to be highly evolved and undergoing rapid evolving at the present time. A spectral type of F0 is assigned to the variable considering the results from both the spectroscopy and photometry. (c) 2006 Published by Elsevier B.V. |
