| 1 | Pulsation and Long-Term Variability of the High-Amplitude δ Scuti Star AD Canis Minoris显示文摘Time-series photometry was made for the large-amplitude δ Scuti star AD CMi in 2005 and 2006. High-quality photometric data provided in the literature were used to analyze the pulsation of the star, with the derived multiple frequencies fitted to our new data. Besides the dominant frequency and its harmonics, one low frequency (2.27402 c d -1) is discovered, which provides a reasonable interpretation for the long-noticed luminosity variation at the maximum and minimum light. Combining the nine new times of light maxima determined from the new data with the 64 times collected from the literature, we analyzed the long-term variability of AD CMi with the O - C technique. The results provide the updated value of period of 0.122974478 days, and seem to be in favor of the model of combination of the evolutionary effect and light-time effect of a binary system, of which some parameters are hereby deduced. | Pongsak Kholkhuntod Jian-Ning Fu Chayan Boonyarak Kanokwan Marak Li Chen Shi-Yang Jiang | 2007 | Chinese Journal of Astronomy and Astrophysics2007，7，3： | 0 |
| 2 | Variability Study of the SX Phoenicis Star BL Camelopardalis显示文摘在 V 乐队和白光的 BL 凸轮的光度计的观察在中国的 Xinglong 车站在 2005 ~ 2007 期间被做的新时间系列。频率分析证实二仔细分开了频率, 25.181 d −1 和 25.571 d −1, ,但是 31 32 d −1 的频率在文学报导了没在新数据被检测。最大的光的新时间从我们的轻曲线和在因特网上可得到的那些是坚定的,允许 O−Cdiagram 的更全面的研究,和在文学的最大的光的时间。包括在 1988 前增加并且自从 1992 BL 凸轮和轻时间的效果,在一个二进制系统减少的时期,新解释看起来貌似合理。 | Jian-Ning Fu Chao Zhang Kanokwan Marak Chayan Boonyarak PongsakKhokhuntod Shi-Yang Jiang | 2008 | Chinese Journal of Astronomy and Astrophysics2008，8，2： | 0 |
