本文尝试采用组分夸克质量模型来研究超新星核中二味夸克物质与更稳定的三味夸克物质之间的相变。结果表明,这种跃迁对核心温度、中微子丰度和中微子能量的增加有显著影响,有助于提高超新星爆炸的成功概率。然而,这些参数的平衡值(温度除外)从组分夸克质量模型在这项工作中略大于从其他模型得到的。我们发现组分夸克质量模型也适用于描述超新星核的跃迁。
Constituent quark mass model is adopted as a tentative one to study the phase transition between two-flavour quark matter and more stable three-flavour quark matter in the core of supernovae. The result shows that the transition has a significant influence on the increasing of the core temperature, the neutrino abundance and the neutrino energies, which contributes to the enhancement of the successful probability of supernova explosion. However, the equilibrium values of these parameters (except the temperature) from the constituent quark mass model in this work are slightly bigger than those obtained from the other model. And we find that the constituent quark mass model is also applicable to describing the transition in the supernova core.
