In the h - r diagram below , our sun is now in the main sequence 在以下的赫罗图中,太阳正位于主序上。
Hertzsprung russel diagram 赫罗图解
From the two h - r diagrams below , we can also tell which cluster is older and which is younger 由以下两幅赫罗图中,我们可断言右图表示的星团比较年老。
And we will see that the mass is the most important factor that determines the fate of a star 绘画在赫罗图上,你将会发现恒星的质量是主宰其命运的决定性因素。

I was one of those people who never go anywhere without a thermometer , hot water bottle , raincoat and parachute , wrote author don herold “我属于那种无论到哪儿都得带上温度计、热水瓶、雨衣和伞的人, ”作家唐?赫罗尔德写道。
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。
Before the interstellar cloud contracts , it was very cold and dim . thus , the cloud is represented by a point at the right in the h - r diagram 在星际云收缩之前,它非常冰冷,所以在这个阶段,星际云会位于赫罗图上一个极右的位置。
