Title: 重同位素和p核素生产的统一核合成场所

Abstract: Current r-process models under-produce A<130 nuclei. P-process models either underproduce A<100 and 150<A<165 p-nuclei, or have other limitations. We argue that the puzzles in these two mechanisms can be solved by heavy-ion spallation. Spallation happens in the explosive phase transition from a neutron star to a quark star - the quark-nova. The quark-nova triggers the r-process which creates abundant A>130 nuclei, and spallation fragments these isotopes into A<130 nuclei and all 35 p-nuclei. Our model is universal in relation to a star's age, metallicity, and chemistry. Show Chinese abstract

Abstract: 当前的r过程模型对A<130核素的生成不足。 P过程模型要么对A<100和150<A<165的p核素生成不足，要么有其他限制。 我们认为，通过重离子散裂可以解决这两种机制中的谜题。 散裂发生在中子星向夸克星的爆发相变阶段——即夸克新星。 夸克新星触发r过程，产生大量A>130的核素，并且散裂将这些同位素碎片化为A<130核素和所有35个p核素。 我们的模型在与恒星的年龄、金属量和化学组成的关系上是普遍的。
