h-r diagram
解釋
赫羅圖-
In the h - r diagram below, our sun is now in the main sequence
在以下的赫羅圖中,太陽正位於主序上。 -
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
在星際雲收縮之前,它非常冰冷,所以在這個階段,星際雲會位於赫羅圖上一個極右的位置。 -
Upon contraction under its own gravity, the interstellar cloud heats up, and thus moving to the left in the diagram. note that the position of a star in the h - r diagram shows its physical properties, not its position in the sky
當星際雲收縮,它會變得越來越熱,而它在赫羅圖上的位置亦會向左移動注意:恆星在赫羅圖上的位置顯示了它們的物理特性,而非其在天空的位置。 -
We expect stars with short life span are already dead. when we plot the stars of a cluster in the h - r diagram, we see the more massive stars, which are stars in the upper left, have already evolved off the main sequence
換句話說,星團內壽命短的星應該已經死去,當我們把星團內的星以赫羅圖的形式繪畫出來時,我們發覺位於圖中左上角的大質量恆星果然已經步入死亡階段,離開了主序星的行列。
