| 1. | The origins of stars of differing spectral types must be dissimilar . 不同光谱型星的起源必然是不一样的。 |
| 2. | A convenient classification of stars is based upon the observed sequence of spectral types . 一种实用的恒星分类法是基于测得的光谱类型序列。 |
| 3. | The hot, massive, high-luminosity stars of spectral types o and b are not distributed uniformly over the galaxy but are grouped into extensive, separate aggregates that have come to be called associations . O型和B型的大质量高光度热星在银河系中分布并不均匀,而是聚集成为分开的大星群,即所谓星协。 |
| 4. | Orbital calculation of g spectral type globular clusters in the galaxy 型球状星团的轨道计算 |
| 5. | The corona activity of late - type main sequence stars also depend on the stellar spectral type 晚型主序星的冕球活动也表现出对恒星光谱型的依赖性。 |
| 6. | The hertzsprung - russell diagram serves this purpose . it is a plot of absolute magnitude against surface temperature i . e . , spectral type of stars 简单来说,赫罗图把大量恒星的绝对星等和表面温度或谱型关系以图表方式显示出来。 |
| 7. | From o to m . hottest stars are spectral type o , and coolest stars are type m . the standard mnemonic to remember the sequence of spectral types is oh , be a fine girl , kiss me 由最热的o型恒星开始,接著是b型a型f型g型k型,最后是最冷的m型。 |
| 8. | One reason is the change of interior convection zone with spectral type produce the phenomena ; another reason is the differential rotation of f type stars exist a upper limit 这一拐点的出现可能是f型主序星的对流区的变化影响形成的,也可能是f型主序星在f5附近存在较差自转的上限形成的。 |
| 9. | The hot , massive , high - luminosity stars of spectral types o and b are not distributed uniformly over the galaxy but are grouped into extensive , separate aggregates that have come to be called associations O型和b型的大质量高光度热星在银河系中分布并不均匀,而是聚集成为分开的大星群,即所谓星协。 |
| 10. | 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。 |
