摘要 作者于1986年3月间,对短周期RS CVn型双星WY Cnc进行了uvby四色光电观测。采用改进了的包含黑子微分改正的W-D程序,对b和y光变曲线,以及Chambliss 1965年发表的B和V两色曲线,分别进行了食外测光畸变波的黑子模拟分析,得出WY Cnc在两个时期中,其主子星均存在两个黑子活动区,并给出它们的大小、位置和活动区平均温度结果。新的测光质比为q=m_2/m_1=0.454±0.005。WY Cnc属主序不接双星。 Four color uvby observations of the short period RS CVn system WY Cnc were made, in March, 1986. Three times of primary minimum were determined. With the starspot assumption, the photometric distortion waves were analysed of the b and y observations of the authors' and the B and V observations of Chambliss' (1965), respectively. The analyses were basen on the W-D program of 1983 edition and the differential correction computing code for spot parameters designed by Zhai and Chen (1988). Two spots were found on the surface of the primary component in each of the two different epoches. Table 5 presents the starspot parameters, including the latitudss, longitudes, radii and temperatures as well as their errors. Table 6 are the Roche model parameters in which the new photometric mass ratio q (=m2/m1) is 0.454±0.005. The photometric results show that WY Cnc is a Main Sequence detached system.
