致密星的自旋下降和一级相变的能量释放
Spin-down of compact stars and energy release of a first-order phase transition
摘要：
在中子星的自旋下降过程中，强子物质到夸克物质的解除禁闭相变可以连续发生。如果是一级相变，则会导致潜热的释放。我们研究了含有强子物质和夸克物质混合相的旋转混合星模型的这种去禁闭相变的能量释放。通过研究无限小压缩的随机过程，计算了每个重子释放的潜热。最后，通过输入混合相的状态方程，并基于恒星的旋转结构方程，自洽地得到了去禁闭相变的加热亮度。
英文摘要：
The deconfinement phase transition from hadronic matter to quark matter can continuously occur during spins down of neutron stars. It will lead to the release of latent heat if the transition is the first-order one. We have investigated the energy release of such deconfinement phase transition for rotating hybrid stars model which include mixed phase of hadronic matter and quark matter. The release of latent heat per baryon is calculated through studying a randomly process of infinitesimal compressing. Finally, we can self-consistently get the heating luminosity of deconfinement phase transition by imputing the EOS of mixed phase, and based on the equation of rotation structure of stars.
