[漢羅] Tī 火舌星雲內底

[火舌星雲][The Flame Nebula] 是一个 tī 可見光波段特別有名 ê 影像。 因為伊 tī 獵戶座皮帶 ê 恆星形成區真厚雲、密實。 Tī 皮帶上東爿彼粒參宿一，離咱差不多有 1400 光年遠。 參宿一是 tī 這張 Spitzer 太空望遠鏡翕 ê 紅外線影像正爿邊仔一粒真光 ê 恆星。 這幅紅外線影像差不多有 15 光年闊。 你會當看著星雲內底發光 ê 氣體 kah 烏暗 ê 塗粉雲。 內底有足濟最近產生 ê 恆星，攏 tī NGC 2024 星團內底，to̍h 集中 tī 中央。 Tī NGC 2024 內底 ê 恆星，in ê 年歲 ùi 20 萬歲到 150 萬歲遐爾少年。 事實上，資料表示，少年恆星主要集中 tī 火舌星雲星團中間。 這 kah 恆星形成上簡單 ê 模型恆星托兒所顛倒反。 模型預測 恆星形成 應該是 tī 分子雲中心上厚雲 ê 所在開始。 這个結果 需要一个閣較複雜 ê 模型來解說 [火舌星雲內底][inside the Flame Nebula t] ê 恆星形成。

[English] Inside the Flame Nebula

[The Flame Nebula][The Flame Nebula] is a stand out in optical images of the dusty, crowded star forming regions toward Orion's belt and the easternmost belt star Alnitak, a mere 1,400 light-years away. Alnitak is the bright star at the right edge of this infrared image from the Spitzer Space Telescope. About 15 light-years across, the infrared view takes you inside the nebula's glowing gas and obscuring dust clouds though. It reveals many stars of the recently formed, embedded cluster NGC 2024 concentrated near the center. The stars of NGC 2024 range in age from 200,000 years to 1.5 million years young. In fact, data indicate that the youngest stars are concentrated near the middle of the Flame Nebula cluster. That's the opposite of the simplest models of star formation for a stellar nursery that predict star formation begins in the denser center of a molecular cloud core. The result requires a more complex model for star formation [inside the Flame Nebula][inside the Flame Nebula e].
