Diagram caption:
O 型恒星 HD 235673 的光譜，X 軸為波長（納米），Y 軸為通量。圖的上半部分顯示瞭相同的光譜，但高通量的波長為亮斑，低通量的波長為暗斑。400 納米到 700 納米之間的綫條顔色與人眼看到的該波長光的顔色基本一緻。在 400 納米以下和 700 納米以上，人眼幾乎看不到光，這兩條綫的顔色分彆為藍色和紅色。
黑綫錶示恒星大氣中不同元素的原子和離子造成的光譜吸收綫。這些原子和離子會吸收特定波長的光，從而在光譜中形成尖銳的暗綫。這些綫條的強度取決於恒星大氣層的溫度。如果兩顆恒星的大氣層溫度不同，那麼由相同元素混閤而成的兩顆恒星的光譜中可能會齣現大相徑庭的光譜綫。對於 O 型恒星來說，最重要的特徵是由電離氦引起的少量譜綫。O 型恒星中的這些譜綫比冷態恒星中的譜綫更強。氦原子和氫原子的譜綫也齣現在光譜中。光譜的藍色端比紅色端有更多的通量。
