当地球经过的恒星，它会导致小减少恒星的亮度。

As the planet passes by the star , it causes a small decrease in the star 's brightness .

这个很有趣的结果指出，大质量恒星爆炸所产生的碎片云，其外观和某些小质量恒星所产生的行星状星云相似。

The intriguing result implies that the massive star 's explosion has produced a shape similar to what is seen in some planetary nebulae associated with lower mass stars .

考虑了重元素扩散效应之后可以使恒星的结构演化模型更加完善，这不仅对小质量恒星的研究有重要的影响，同时对研究整个恒星结构演化中的物理问题也具有一定的意义。

Considering the heavy element diffusion , it could perfect the stellar structure models . It is important to study the physical problems about the stellar structure and evolution not only for low-mass stars but also for all the stars .
