[漢羅] Webb 翕--ê WR 140 ê 塗粉殼

這寡奇怪 ê 光環是啥物？ 這寡光環是較厚 ê 塗粉，應該是一个球形殼。 In 是按怎製造出來--ê，到今猶是一个 研究主題。 毋閣咱知影 in 是 tī 佗位製造出來--ê：是一个 tī 6000 光年 遠 ê 天鵝座 內底 ê 雙星系統。 彼是一个 Wolf-Rayet 星 WR 140 主導 ê 雙星系統。 Wolf-Rayet 星 是大質量恆星，而且伊上有名 ê 是伊有一个 生狂 ê 恆星風。 In 嘛會製造 kah 噴出 重元素，親像是 星際 塗粉 ê 構成成份，碳素。 雙星 系統另外彼粒恆星嘛是足光 ê 大質量恆星，毋閣 無遐爾活潑。 這兩粒 大質量 恆星 tī 長株圓軌道 咧互踅，in 每 8 年就會倚近一擺 互相唱聲。 In 兩粒上倚 ê 時陣，雙星系統 ê X-光 發射線 就會增加，kā 塗粉捒出去宇宙中，就按呢產生新 ê 塗粉殼。 這張 紅外線 影像是新 ê Webb 太空望遠鏡 翕--ê，有看著足濟 足讚 ê 細節，kah 遮爾濟塗粉殼，這是以前攏毋捌看過--ê。

[English] Dust Shells around WR 140 from Webb

What are those strange rings? Rich in dust, the rings are likely 3D shells -- but how they were created remains a topic of research. Where they were created is well known: in a binary star system that lies about 6,000 light years away toward the constellation of the Swan (Cygnus) -- a system dominated by the Wolf-Rayet star WR 140. Wolf-Rayet stars are massive, bright, and known for their tumultuous winds. They are also known for creating and disperseng heavy elements such as carbon which is a building blocks of interstellar dust. The other star in the binary is also bright and massive -- but not as active. The two great stars joust in an oblong orbit as they approach each other about every eight years. When at closest approach, the X-ray emission from the system increases, as, apparently, does the dust expelled into space -- creating another shell. The featured infrared image by the new Webb Space Telescope resolves greater details and more dust shells than ever before.
