It is well known that neutron stars spin down due to magnetic dipole radiation. The deconfinement phase transition of hadron matter to quark matter is expected to occur in the dense cores of the stars during spin-down. The phase transition continuously takes place inducing not only structural changes but also energy release in case of a first-order phase transition. The generation of energy increases the internal energy of the stars which is called deconfinement heating. The temperature of the stars arise when the deconfinement heating appears in the cores. We explore the deconfinement signature by studying the changes of surface temperature in the thermal evolution process of neutron stars.

Quark deconfinement as supernova explosion engine for massive blue-supergiant stars
蓝超巨星发展成为核心坍缩超新星-宇宙中最具能量的爆发之一-当恒星核心的所有核燃烧燃料耗尽时。先前的尝试未能解释观测到的这种恒星的爆炸，这些恒星的零龄主序星质量为50 M $_\odot$或更大。在这里，我们利用在很大程度上不确定的高密度物质的状态，并连接这样的恒星爆炸与一级相变从核物质的夸克-胶子等离子体的建模。由此产生的高能超新星爆炸可以解释多种光变曲线，从奇特的II型到超亮事件。残余物是具有夸克物质核心的中子星，称为混合星，在出生时约为2~M $_\odot$。由于第二次中微子爆发的释放，这种星系事件可以被观测到。它的观测将证实这种一级相变在密度相关的天体物理学。
