重子物质的暗伴星III
Dark companion of Baryonic matter, III
摘要：
无论在哪里谈论暗物质，都是在有可观测物质和相关的未解决的动力学问题需要解决的情况下。我们将这一观察提升到公理的地位，并推测每一个重子物质都有一个暗伴星，它的大小、分布都遵循一定的规则。为了系统地研究这个命题，我们求助于旋涡星系的自转曲线。它们具有非经典的特征。首先，我们设计一个时空度量银河系周围，以适应这些功能。接下来，我们计算一个假设的暗物质的密度和压力，它可以产生这样一个时空。在弱场区，对于质量为$M$的球形分布，我们能够指定一个暗的完美气体伴星，其密度几乎与$M^{1/2}$成正比，并且几乎作为$r^{-2}$消失。然而，鉴于可观测质量与其暗伴星之间的这种有序关系，人们可以选择将整个场景解释为另一种引力理论。
英文摘要：
Wherever one talks of dark matter, one does so where there is an observable matter and an associated unsolved dynamical issue to be settled. We promote this observation to the status of an axiom and conjecture that there is a dark companion to every baryonic matter, subject to certain rules as regards its size, distribution. To pursue the proposition in a systematic way we resort to the rotation curves of spiral galaxies. They have non classical features. First, we design a spacetime metric around the galaxy to accommodate these features. Next we calculate the density and pressure of a hypothetical dark matter that could generate such a spacetime. In the weak field regime and for a spherical distribution of mass $M$, we are able to assign a dark perfect gas companion, whose density is almost proportional to $M^{1/2}$ and fades away almost as $r^{-2}$. However, in view of this orderly relation between the observable mass and its dark companion, one may choose to interpret the whole scenario as an alternative theory of gravitation.
