论文摘要
我们研究了旋转玻色子恒星的空间时间中恒定特异性角动量分布的抛光甜甜圈。在这样的空间时，厚的摩托车可以在Kerr太空时表现出独特的功能。例如，在逆行托里（Tori）的背景下，它们可能拥有两个尖端连接或不连接的中心。旋转的玻色子恒星还具有静态环，在Kerr空间时都不存在。该静态环由静态轨道组成，其中颗粒相对于无穷大的零角动量观察者静止。在这里，我们表明静态环的存在允许逆行厚的圆环的相关静态表面，其中在静态表面内流体沿前进方向移动。我们对逆行抛光甜甜圈进行了分类，并提供了几个具体的例子。
We investigate Polish doughnuts with a uniform constant specific angular momentum distribution in the space-times of rotating boson stars. In such space-times thick tori can exhibit unique features not present in Kerr space-times. For instance, in the context of retrograde tori, they may possess two centers connected or not by a cusp. Rotating boson stars also feature a static ring, neither present in Kerr space-times. This static ring consists of static orbits, where particles are at rest with respect to a zero angular momentum observer at infinity. Here we show that the presence of a static ring allows for an associated static surface of a retrograde thick torus, where inside the static surface the fluid moves in prograde direction. We classify the retrograde Polish doughnuts and present several specific examples.
