阿佩普來自韋伯的不尋常塵埃殼
Apep: Unusual Dust Shells from Webb

發表日期:2025-11-24
是什麼造就了這座與眾不同的太空雕塑?恆星。 2024 年,美國國家航空航天局的詹姆斯-韋伯太空望遠鏡用紅外光觀測到了這個不同尋常的漩渦和外殼系統,它被稱為 Apep。觀測結果表明,這種不尋常的形狀源於兩顆大質量的沃爾夫-雷葉星每隔 190 年繞著對方執行一次,每一次接近都會導致新的塵埃和氣體外殼被排出。這些外殼上的洞被認為是由第三顆環繞的恆星造成的。這種恆星塵埃舞可能會持續數十萬年,只有當其中一顆大質量恆星耗盡內部核燃料,並在伽馬射線爆發的同時爆發超新星時才可能結束。 建立你自己的恆星系統今日天文之謎
原文:What created this unusual space sculpture? Stars. This unusual system of swirls and shells, known as Apep, was observed in unprecedented detail by NASA’s James Webb Space Telescope in infrared light in 2024. Observations indicate that the unusual shape originates from two massive Wolf-Rayet stars orbiting each other every 190 years with each close passes causing a new shell of dust and gas to be expelled. Holes in these shells are thought to be caused by a third orbiting star. This stellar dust dance will likely continue for hundreds of thousands of years, possibly ending only when one of the massive stars runs out of internal nuclear fuel and explodes in a supernova punctuated by a burst of gamma-rays.
