[漢羅] 動畫:烏洞 kā 恆星拆食落腹

恆星若是 kah 烏洞行傷倚,會發生啥物代誌? 烏洞 會 kā 伊拆食落腹,毋過實際上會按怎食? 其實這毋是因為烏洞 ê 引力傷懸,是因為 引力差 kā 恆星 解體矣。 這支動畫 有解說這个解體過程。 代先你會看著一粒恆星接近烏洞。 紲落來,你會看著伊踅烏洞 ê 速度愈來愈緊,tī 伊愈來愈倚烏洞 ê 時陣,恆星 ê 外層大氣 嘛去予搝開。 恆星 ê 大氣,大部份攏湠去深空內底,毋過猶是有一寡仔繼續踅烏洞咧行,形成一塊 吸積盤。 這个 動畫 ê 第二部份,是𤆬你 到吸積盤附近看烏洞。 嘛𤆬你看 重力透鏡 造成 奇怪 ê 視覺效果。 你甚至會當看著較遠彼爿 ê 吸積盤。 落尾,你會當看著烏洞自轉軸方向 噴出來 ê 其中一條 噴射流。 理論 模型 表示講,這寡噴射流毋但會擲高能氣體出來,嘛會產生高能 中微子。 其中一款中微子,最近可能捌 tī 地球揣著

[English] Animation: Black Hole Destroys Star

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.
