标题： Neutron-mirror neutron oscillations in stars

摘要： 基于一种新提出的中子-镜像中子（$n-n'$）振荡的镜像物质模型[Phys. Lett. B 797, 134921 (2019)]，在新理论下提出了单星的演化和核合成。在新模型中，$n-n'$振荡是由两个区间的粒子之间非常小的质量差引起的。具有新$n-n'$模型的新理论可以比传统观点更令人信服地展示演化。特别是，许多恒星的观测结果强烈支持新理论和新$n-n'$模型。例如，白矮星和中子星的前体质量限制和结构、两种不同类型的核心坍缩超新星（II-P 和 II-L）、重元素的合成、恒星的脉动现象等，都可以在新理论下很容易且自然地解释。 显示英文摘要

摘要： Based on a newly proposed mirror-matter model of neutron-mirror neutron ($n-n'$) oscillations [Phys. Lett. B 797, 134921 (2019)], evolution and nucleosynthesis in single stars under a new theory is presented. In the new model, $n-n'$ oscillations are caused by a very small mass difference between particles of the two sectors. The new theory with the new $n-n'$ model can demonstrate the evolution in a much more convincing way than the conventional belief. In particular, many observations in stars show strong support for the new theory and the new $n-n'$ model. For example, progenitor mass limits and structures for white dwarfs and neutron stars, two different types of core collapse supernovae (II-P and II-L), synthesis of heavy elements, pulsating phenomena in stars, etc, can all be easily and naturally explained under the new theory.
