Hagedorn流体的引力坍缩

Gravitational collapse of Hagedorn fluids

Daniele Malafarina

摘要:

我们考虑一个玩具模型的相对论性崩溃的均匀的完美流体,考虑到状态方程的高密度物质,在Hagedorn阶段的形式,和半经典修正的强场。我们表明,崩溃达到一个临界的最小尺寸,然后反弹。我们讨论了坍缩停止并形成致密物体的条件。我们认为,影响的模型,如这里提出的是非常重要的天体物理学,因为它们表明,黑洞可能不是唯一的最终结果非常大质量的恒星崩溃。

英文摘要:

We consider a toy model for relativistic collapse of an homogeneous perfect fluid that takes into account an equation of state for high density matter, in the form of an Hagedorn phase, and semiclassical corrections in the strong field. We show that collapse reaches a critical minimum size and then bounces. We discuss the conditions for collapse to halt and form a compact object. We argue that implications of models such as the one presented here are of great importance for astrophysics as they show that black holes may not be the only final outcome of collapse of very massive stars.
