| 1. | Between chromospheric activity index and corona activity index of ms stars , there exist good linear relativity . but for evolution stars , this relation show a large dispersion 我们发现主序星的色球与冕球磁活动指数存在着很好的线性相关性,而演化恒星的则表现出较弱的相关性。 |
| 2. | From the distribution of rotation period and convection parameter of m type stars , stellar chromospheric activity of m type stars depart from the anticipation of a . dynamo theory obviously 从m型主序星的自转周期的和恒星内部对流区随色指数的分布来看, m型主序星的色球活动行为与发电机理论的预期有明显的差异。 |
| 3. | By the reserching the relation between stellar chromospheric activity and color index , we find that stellar ages play a pivotal role for producing vaughan - preston gap of ms stars 通过主序星的色球活动对恒星色指数不同依赖关系的研究,我们分析了vaughan ? preston间隙产生的原因,分析结果显示恒星的年龄在这一间隙的形成中扮演了重要的角色。 |
| 4. | Furthermore , we also reserch the influence of setllar age to stellar activity of late - type stars . the relation of stellar chromospheric activity and rotation of late - type main sequence stars depend on stellar spectral type 大样本分析显示晚型主序恒星的色球活动与恒星自转参量的研究晚型主序恒星的色球活动与恒星自转参量间的关系表现出对恒星光谱型的依赖。 |
| 5. | The relation between stellar chromospheric activity and rotation of evolution stars have a good relativity . but meticulous analysis show chromospheric activity of evolution stars depend on stellar spectral type and effective temperature strongly . we provide several possible explain for those phenomena 但是细致分析显示演化恒星色球活动水平随恒星自转周期间的分布对恒星光谱型和恒星表面有效温度有很强的依赖,并对这些现象提出了几种可能的解释。 |
| 6. | Though this departure is not obvious , the result still support the conclusion in the analysis of stellar chromospheric activity . for evolution stars , wo do n ' t , obtain significative result because the deficient samples . but the statistics analysis show the distrbution of corona activity of late type with color index and rotation period exist upper limit 演化恒星的磁冕球活动在色指数和自转周期的分布上都显示出冕球磁活动存在上限的现象,并且对冕球磁活动上限的拟合表明在色指数b一v为1 . 0附近和自转周期 |
| 7. | For a - early f type ms stars , stellar chromospheric activity decrease with stellar rotation period , but increase with rossby number ; for m type ms stars , stellar chromospheric activity increase with stellar rotation period and rossby number , and stellar chromospheric activity reach saturation at large color index ; for the ms stars between mid - f to m type , stellar chromospheric activity decrease with stellar rotation period and rossby number A ?早f型主序恒星的自转周期和恒星对流区的随色指数的分布明显地影响着这些恒星的色球活动行为。而m型主序星的色球活动水平基本上随自转参量的增大呈上升趋势,并且m型主序星的色球活动水平在色指数较大时趋于饱和。 |
