论文摘要
We combine the ideas of a Weyl scaling invariant dark energy action, which eliminates black hole horizons, with the ``gravastar'' idea of a jump in the hole interior from a normal matter equation of state to an equation of state where pressure plus density approximately sum to zero.使用需要连续压力的Tolman-Oppenheimer-Volkoff方程式，我们提出了数学笔记本，其中grastar的结构完全由动作和状态方程控制，而RADII的结构变化发生在动力学中，而不是提前指定。这些笔记本即使在零宇宙常数中也可以工作，但是当宇宙常数为非零时，我们会通过标准压力驱动的等温等温线风理论的相对论扩展来计算出一个很小的黑洞````'''。
We combine the ideas of a Weyl scaling invariant dark energy action, which eliminates black hole horizons, with the ``gravastar'' idea of a jump in the hole interior from a normal matter equation of state to an equation of state where pressure plus density approximately sum to zero. Using the Tolman-Oppenheimer-Volkoff equation, which requires continuous pressure, we present Mathematica notebooks in which the structure of the gravastar is entirely governed by the action and the equation of state, with the radii where structural changes occur emerging from the dynamics, rather than being specified in advance. The notebooks work even with zero cosmological constant, but when the cosmological constant is nonzero, there is a very small black hole ``wind'' that we calculate by a relativistic extension of standard pressure driven isothermal stellar wind theory.
