从主序星到中子星的演化路径尚未确定。然而，以下似乎与已发表的模型相同1，3：（a）前中子星星阶段有一个非常致密的碳-氧核心，质量为Mc = 1.4 M，周围是更大质量的氢和氦壳燃烧外壳;恒星的总质量为Mc = 4 M。核心最初通过传统的中微子发射过程保持在碳点火温度以下。
The evolutionary path from main sequence stars to neutron stars has not yet been definitively determined. The following seems, however, common to published models1,3: (a) The pre-neutron star stage has a very dense carbon-oxygen core of mass Mc˜1.4M⨀, surrounded by a more massive hydrogen and helium shell-burning envelope; the total stellar mass is ˜ 4 to 8M⨀. The core is initially kept below the carbon ignition temperature by conventional neutrino emission processes.
