動畫黑洞摧毀恆星
Animation: Black Hole Destroys Star
發表日期：2024-06-16
如果恆星太靠近黑洞會發生什麼？黑洞會把它撕成碎片--但怎麼撕呢？問題並不在於高引力本身，而是恆星之間的引力差異造成了破壞。 在展示這種分解的動畫影片中，你首先會看到一顆恆星正在接近黑洞。 隨著軌道速度的增加，恆星的外部大氣層在最接近黑洞時被撕裂。 恆星的大部分大氣層散入深空，但也有一些繼續圍繞黑洞執行，形成了一個吸積盤。動畫將帶你進入吸積盤，同時向黑洞看去。包括引力透鏡的奇特視覺效果在內，你甚至可以看到圓盤的遠側。 最後，你將看到沿自旋軸噴出的噴流。 理論模型表明，這些噴流不僅會排出高能氣體，還會產生高能中微子--最近在地球上可能就看到了其中的一個。 幾乎超空間隨機 APOD 生成器
原文：What happens if a star gets too close to a black hole? The black hole can rip it apart -- but how? It's not the high gravitational attraction itself that's the problem -- it's the difference in gravitational pull across the star that creates the destruction. In the featured animated video illustrating this disintegration, you first see a star approaching the black hole. Increasing in orbital speed, the star's outer atmosphere is ripped away during closest approach. Much of the star's atmosphere disperses into deep space, but some continues to orbit the black hole and forms an accretion disk. The animation then takes you into the accretion disk while looking toward the black hole. Including the strange visual effects of gravitational lensing, you can even see the far side of the disk. Finally, you look along one of the jets being expelled along the spin axis. Theoretical models indicate that these jets not only expel energetic gas, but also create energetic neutrinos -- one of which may have been seen recently on Earth.
