| 摘 要： | 本文将1983年版的Wilson-Devinney方法程序,扩展到包含黑子参数的微分改正解,并提出黑子纬度的网络测定方法,由此,对RS CVn型食双星RT CrB的食外测光扰动波,进行了黑子模拟解,得出其次子星上两个黑子的位置,大小和温度,其理论光变曲线能较好地重现畸变波的观测特征。作者对黑子模型参数微分改正解的收敛性问题和不定性问题进行了初步讨论。

| Abstract: | In the present paper, the function of Wilson-Devinney program of 1983 edition was extended to cover the differential correction solution of spot parameters. A grid method was used to determined the probable spot latitude. Using the W-D program, the distortion wave of the RS CVn system RT CrB was successfully analysed based on two spots' assumption on its secondary component. The distorted light curves can be accurately reproduced by spot solution. Authors have made a preliminary discussion about the convergent problems and the probable uncertainties in spot solution. |
