具有纯量函数的自相似完美流体的引力坍缩

Gravitational Collapse of Self-similar Perfect fluid with Scalar function

Sanjay B. Sarwe, Gulshan O. Makkad

摘要:

研究了含有线性状态方程的具有标函数的自相似球对称理想流体时空。时空引力坍缩条件的研究确定了标量函数具有虚部形式$ϕ(X) = i \; α_o \; φ(X)$,$φ(X)$是自相似变量$X$的非零实值函数.云的引力坍缩,根据相对于线性状态方程的物理合理的初始数据的选择,最终导致黑洞或裸奇点的形成。

英文摘要:

The self-similar spherically symmetric perfect fluid space-time with scalar function incorporating linear equation of state is studied. The investigation of gravitational collapse conditions on the space-time determines that scalar function has an imaginary form $ϕ(X) = i \; α_o \; φ(X)$, $φ(X)$ being a non-zero real valued function of self-similar variable $X$. The gravitational collapse of cloud ends into the formation of black hole or naked singularity according to the choice of physically reasonable initial data relative to the linear equation of state.
