Life Cycle Ofthe Stars
The massive precursors to neutron stars often spin. 中子星的大质量前身通常会旋转。 When they collapse, 当它们崩垮时, stars that are typically millions of kilometers wide 通常有数百万公里宽的星体 compress down to neutron stars that are only about 25 kilometers across. 会被压缩到只有二十五公里宽...

Observations of early-type M stars suggest that there are two characteristic cycle times, one of order one year for fast rotators (Prot < 1 day) and another of order four years for slower rotators. For a sample of fast-rotating stars, the equator-to-pole diff...
