In this work, we study the dark energy accretion phenomena onto (n + 2)-dimensional Schwarzschild black hole and (n + 2)-dimensional Morris–Thorne wormhole. We obtain the (n + 2)-dimensional Schwarzschild black hole mass and (n + 2)-dimensional Morris–Thorne wormhole mass and their rate of change of masses due to accretion. For the dark energy component, we consider Tsallis, modified Rényi and “modified” Sharma–Mittal holographic dark energy (HDE) and new agegraphic dark energy (NADE). We also find the black hole mass and the wormhole mass in terms of redshift when cold dark matter and the specified forms of dark energies accrete onto them. In most cases, the black hole mass increases, and wormhole mass decreases for HDE and NADE accretions. The only exception is the Sharma–Mittal NADE, where the black hole mass decreases and wormhole mass increases during the evolution of the Universe. However, the slope of increasing/decreasing mass significantly depends on the dimension in almost all cases.

Tsallis、Rényi 和 Sharma-Mittal 暗能量吸积到高维史瓦西黑洞和莫里斯-索恩虫洞上

在这项工作中,我们研究了暗能量吸积现象到(n + 2)维施瓦西黑洞和(n + 2)维莫里斯-索恩虫洞。我们获得(n + 2)维施瓦西黑洞质量和(n + 2)维莫里斯-索恩虫洞质量及其因吸积引起的质量变化率。对于暗能量成分,我们考虑 Tsallis、改良的 Rényi 和“改良的”夏尔马-米塔尔全息暗能量 (HDE) 和新时代暗能量 (NADE)。当冷暗物质和特定形式的暗能量吸积到黑洞质量和虫洞质量上时,我们还发现了黑洞质量和虫洞质量。在大多数情况下,对于 HDE 和 NADE 吸积,黑洞质量会增加,而虫洞质量会减少。唯一的例外是夏尔马-米塔尔 NADE,在宇宙演化过程中,黑洞质量减少而虫洞质量增加。然而,在几乎所有情况下,增加/减少质量的斜率都显着取决于尺寸。
