论文摘要
基于以下假设：QCD相图给出了在不同的机制下对Hadronic和Quark物质的现实图片，因此可以声称在通常命名为混合中性星星的紧凑物体中可能存在夸克芯，甚至可能存在一个纯粹的奇怪恒星。在这项工作中，我们探讨了如何通过强磁场的存在以及如何通过夸克相的参数影响它的相变，为此我们使用与矢量相互作用的MIT模型。当哈德子变成脱糊状夸克时，假定相变为保存风味。使用NL3 $ωρ^\ ast $量子HADRODERANICS参数化计算状态的HADRONIC方程。我们发现磁场略微降低了相变和潜热的压力和化学潜力，后者非常依赖于模型。
Based on the assumption that the QCD phase diagram gives a realistic picture of hadronic and quark matter under different regimes, it is possible to claim that a quark core may be present inside compact objects commonly named hybrid neutron stars or even that a pure strange star may exist. In this work we explore how the phase transition is modified by the presence of strong magnetic fields and how it is impacted by parameters of the quark phase, for which we use the MIT-model with vector interactions. The phase transition is assumed to conserve flavor when hadrons turn into deconfined quarks. The hadronic equation of state is calculated with the NL3$ωρ^\ast$ parametrization of quantum hadrodynamics. We find that the magnetic field slightly reduces the pressure and chemical potential of the phase transition and the latent heat, the latter being very model dependent.
