论文摘要
我们已经研究了阴影及其光度，分别在静态球形积聚和插入的球形增生下进行静态和规则的幻影紧凑型物体。与通常的Schwarzschild黑洞相比，幻影头发的存在产生了更大的黑洞阴影和较深的图像。在两个球形积聚模型中，随着幻影参数的增加，最大发光度发生在光子环和阴影中的中央区域的亮度下降，但在远离阴影的区域中，图像的光度略有增加。幻影虫洞及其光度的图像具有相似的行为。此外，随着Phantom电荷参数$α$的增加到临界值的临界值从黑洞变为蠕虫，因此特定强度有一个跳跃，这也出现在缓慢旋转的情况下。这意味着幻影头发都印在了阴影半径和紧凑型物体周围电磁通量辐射的强度上。
We have studied the shadow and its luminosity for a static and regular phantom compact object under the static spherical accretion and the infalling spherical accretion, respectively. Comparing with the usual Schwarzschild black hole, the presence of phantom hair yields the larger black hole shadow and the darker image. In both spherical accretion models, with the increase of phantom parameter, the maximum luminosity occurred at photon ring and the brightness of the central region in the shadow decrease, but in the region far from the shadow, the luminosity of image slightly increases. The image of a phantom wormhole and its luminosity have similar behaviors. Moreover, as the phantom charge parameter $α$ increases up to the critical value at where the compact object changes from black hole to wormhole, there exists a jump for the specific intensity, which also appears in the slowly rotating case. This implies that the phantom hair is imprinted on both the shadow radius and the intensity of the electromagnetic flux radiation around compacted object.
