同它在主星序上的大小相比，恒星现在就成了巨星。
In comparison to their size on the main sequence, the stars now become giants.
当这些亮而且质量大的恒星耗尽了氢燃料时，它们就开始从主星序上端脱离。
As these luminous and massive stars exhaust their hydrogen fuel, they begin to depart from the upper end of the main sequence.
这些研究者就顽固地争辩说，恒星沿主星序向下的演化，应该伴随着连续的和很显著的质量损失。
These investigators tenaciously argued the evolution of stars downward along the sequence ought to be accompanied by a continuous and very substantial loss of mass.
天蝎座delta和仙后座gamma都是正在远离主星序的快速自转的恒星，并且它们不时地从其赤道区域抛出物质。
Both Delta Sco and Gamma cas are rapidly rotating stars that are evolving off the main sequence and occasionally flinging mass from their equators.
描绘出了恒星在星际气体尘埃中诞生，在主星序阶段稳定演化，最后以白矮星，中子星或黑洞告终的一生经历轮廓。
It also gives a general picture of their origin in the interplanetary dust of gas, their stable evolution in the stage of main-sequence and their end with White Dwarf, Neution Star and Black Hole.
他们计算出这种星体的数量是我们“主星序星体”的两倍。我们的太阳就属于“主星序星体”，现在仍然通过燃烧氢燃料发光。
They calculated that they could be almost twice as common as "main-sequence stars" - such as our own Sun - which are still burning through their hydrogen fuel stock.
