| 摘 要： | 以X-ray亮度为标准，选取了16颗G型的年轻类太阳恒星进行了测光观测，并通过IRAF软件经行了测光处理，获得了9颗年轻类太阳恒星的自转周期。结合一些T Tauri型星、零龄主序恒星的自转周期，X-ray亮度得到自转较快的类太阳恒星与自转较慢的这些恒星比较，前者具有更强的X-ray辐射。但是，当恒星自转极快时，却并未发现自转和X-ray辐射强度之间的明显相关性。

| Abstract: | The authors monitored the light variations of 16 young solar-type stars. In the observations, 9 stats showed appreciable periodie light variability. By using the Phase Dispersion Minimization （PDM） and Fourier analysis （PERIOD04）, the rotational periods of these stars were determined. For FITS and main sequence stars, it is found that the faster rotators tend to have higher X - ray luminosities. However, no correlation between the X - my luminosity and rotation periods is detected for the sample stars that rotate ultra fast. |
