[漢羅] 金牛座 T 星 kah Hind 變光星雲

Tī 這張厚塗粉 ê 望遠鏡影像 中央，有一粒柑仔色色調 ê 恆星，金牛座 T 星，伊是 金牛座 T 型變星 這个分類 ê 原型星。 伊倒爿彼个黃色宇宙雲，歷史上 咱 kā 叫做是 Hind 變光星雲 (NGC 1555)。 伊差不多有 650 光年遠，tī 本地泡 kah 金牛座分子雲 交界 ê 所在。 恆星 kah 星雲 ê 輝度變化攏足大 ê，毋閣 in 毋是同齊發生，所以這區才會予人感覺遮爾趣味。 咱這馬 知影 講，金牛座 T 型變星 是較少年 ê 恆星，干焦幾若百萬歲爾爾。 In kah 咱 ê 太陽是仝類 ê 恆星，毋閣 in 是 tī 恆星形成 較早期 ê 階段。 這幅圖 閣較 複雜 ê 部份是，紅外線觀測結果講，金牛座 T 星 是 多星系統 ê 成員之一。 而且 kah 伊有關 ê Hind 變光星雲內底，嘛藏一粒足少年 ê 恆星。 這幅圖 ê 構圖袂䆀。 若是用 金牛座 T 星 ê 距離來推算，這幅圖有 8 光年遐爾闊。

[English] T Tauri and Hind's Variable Nebula

The star with an orange tint near top center in this dusty telescopic frame is T Tauri, prototype of the class of T Tauri variable stars. Next to it (right) is a yellow cosmic cloud historically known as Hind's Variable Nebula (NGC 1555). About 650 light-years away, at the boundary of the local bubble and the Taurus molecular cloud, both star and nebula are seen to vary significantly in brightness but not necessarily at the same time, adding to the mystery of the intriguing region. T Tauri stars are now generally recognized as young (less than a few million years old), sun-like stars still in the early stages of formation. To further complicate the picture, infrared observations indicate that T Tauri itself is part of a multiple system and suggest that the associated Hind's Nebula may also contain a very young stellar object. The well-composed image spans about 8 light-years at the estimated distance of T Tauri.
