[漢羅] L1527 內底 ê 原恆星

暗星雲 L1527 內底 ê 原恆星 干焦 10 萬歲爾爾，伊這馬猶藏 tī 飼伊大漢 ê 氣體塗粉雲內底。 這張是 James Webb 太空望遠鏡 ê NIRCam 翕 ê 紅外線相片。 Tī 星雲頷頸有一條暗帶，彼其實是踅 tī 少年恆星 外口 厚 tut-tut ê 原恆星盤。 Ùi Webb 望遠鏡 ê 紅外線影像看來，原恆星 是藏 tī 原恆星盤內底。 這塊 原恆星盤 是側向--ê，比咱 ê 太陽系較大淡薄仔。 伊 ê 物質，落尾會提去做原恆星。 是講這張影像內底有濟濟星雲 ê 細節。 這个沙漏形星雲，是去予原恆星發出 ê 紅外線 kā 照予光--ê。 這是恆星形成過程中，去予 擲出來 ê 物質 kā 週邊媒介物掃出去 ê 結果。 原恆星得著夠額 ê 質量了後，就會開始轉大人，產生重力崩塌，tī 核心開始進行核融合反應。 暗星雲 L1527 內底 ê 原恆星 離 金牛座內底 ê 恆星形成區 有 460 光年遠。 伊可能 kah 咱太陽系 tī 紅嬰仔時期有相仝。 這張 Webb ê NIRCam 影像 差不多有 0.3 光年闊。

[English] The Protostar within L1527

The protostar within dark cloud L1527 is a mere 100,000 years old, still embedded in the cloud of gas and dust that feeds its growth. In this NIRCam image from the James Webb Space Telescope, the dark band at the neck of the infrared nebula is a thick disk that surrounds the young stellar object. Viewed nearly edge-on and a little larger than our Solar System, the disk ultimately supplies material to the protostar while hiding it from Webb's direct infrared view. The nebula itself is seen in stunning detail though. Illuminated by infrared light from the protostar, the hourglass-shaped nebula's cavities are created as material ejected in the star-forming process plows through the surrounding medium. As the protostar gains mass it will eventually become a full-fledged star, collapsing and igniting nuclear fusion in its core. A likely analog to our own Sun and Solar System in their early infancy, the protostar within dark cloud L1527 lies some 460 light-years distant in the Taurus star-forming region. Webb's NIRCam image spans about 0.3 light-years.
