Chaobergin气体在黑洞上的吸积：更快外流风的形成
Accretion of Chaplygin gas upon black holes: Formation of faster outflowing winds
摘要：
本文研究了修正的Chaubergin气体在不同类型的黑洞上的吸积。修正的Chaobergin气体是暗物质和暗能量组合模型的最佳候选者之一。此外，从场论的观点来看，修正的Chaubergin气体模型等价于具有自相互作用势的标量场。我们制定的方程有关的球形吸积和盘吸积，和各自的风。相应的数值解的流动，特别是速度，并进行了分析。我们发现，修改后的Chaubergin气体的吸积风系统显着改变风的解决方案，产生更快的风，在物理参数的变化，而吸积解决方案定性保持不受影响。这意味着改性后的Chaubergin气体更容易产生外流，这是暗能量进入系统的自然结果。
英文摘要：
We study the accretion of modified Chaplygin gas upon different types of black hole. Modified Chaplygin gas is one of the best candidates for a combined model of dark matter and dark energy. In addition, from a field theoretical point of view the modified Chaplygin gas model is equivalent to that of a scalar field having a self-interacting potential. We formulate the equations related to both spherical accretion and disc accretion, and respective winds. The corresponding numerical solutions of the flow, particularly of velocity, are presented and are analyzed. We show that the accretion-wind system of modified Chaplygin gas dramatically alters the wind solutions, producing faster winds, upon changes in physical parameters, while accretion solutions qualitatively remain unaffected. This implies that modified Chaplygin gas is more prone to produce outflow which is the natural consequence of the dark energy into the system.
