Stars Just Got Bigger 超大质量的巨星 A 300 Solar Mass Star Uncovered 发现超过300太阳质量的蓝超巨星
Using a combination of instruments on ESO’s Very Large Telescope, astronomers have discovered the most massive stars to date, one weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses. The existence of these monsters — millions of times more luminous than the Sun, losing weight through very powerful winds — may provide an answer to the question “how massive can stars be?”
借助于ESO的甚大望远镜(VLT),天文学家发现了创质量纪录的巨星——达300个太阳质量以上,是我们此前公认的(星族II)恒星质量上限——150个太阳的2倍。发现如此怪兽级恒星:光度是太阳的数百万倍,以极速恒星风迅速损失质量——由此产生了一个问题:恒星质量上限到底是多少?
