Astronomers Discover Rare Quadruple Star System 1,900 Light-Years Away

天文學家發現 1,900 光年外罕見的四星系統

One fascinating discovery is TIC 120362137, recognized as the most compact '3+1' system ever found.

一項令人著迷的發現是 TIC 120362137,它被公認為迄今發現最緊湊的「3+1」星系。

It features three stars orbiting tightly enough to fit inside Mercury's path, with a fourth star orbiting further out.

其特點是有三顆恆星緊密繞行,軌道足以容納在水星的路徑內,並有第四顆恆星在更外側繞行。

Scientists predict these stars will eventually merge, potentially forming a white dwarf.

科學家預測這些恆星最終將會合併,有可能形成一顆白矮星。

Another remarkable finding is UPM J1040−3551 AabBab, a 'double-double' system located just 82 light-years away.

另一項引人注目的發現是 UPM J1040−3551 AabBab,這是一個距離僅 82 光年的「雙雙」系統。

Unlike typical systems, it contains two red dwarfs orbited by two cold 'failed stars' known as brown dwarfs.

與典型系統不同,它包含兩顆繞著兩顆寒冷「失敗恆星」(即褐矮星)運行的紅矮星。

This unique configuration acts as a cosmic laboratory, allowing experts to study the elusive nature of brown dwarfs, which are otherwise very hard to detect.

這種獨特的配置就像一個宇宙實驗室,讓專家得以研究褐矮星難以捉摸的本質,因為這些星體平時極難被偵測到。

While reports occasionally misidentify details about these stars, these specific systems offer invaluable data for space science.

儘管報導偶爾會對這些恆星的細節產生誤解,但這些特定的系統為太空科學提供了寶貴的數據。

By studying their evolution and composition, astronomers gain better insights into how complex stellar architectures form and change over time.

藉由研究它們的演化與組成,天文學家能更深入了解複雜的恆星結構是如何隨時間形成並變化的。
