[漢羅] 去予風吹開 ê NGC 3199

NGC 3199 離咱有 12,000 光年遠,是一隻 tī 南天航行 ê 星座,龍骨座,內底發光 ê 宇宙雲。 這个星雲 tī 狹頻假色影像 內底,有 75 光年闊。 雖然講這个深空影像差不多看會著規个完整 ê 氣波形體,毋閣伊看起來趨一爿,tī 面頂邊仔彼搭較光。 Tī 中央是 Wolf-Rayet 星,伊是一个大質量、高溫、短命 ê 恆星,會產生足強 ê 恆星風。 實際上,咱知影 Wolf-Rayet 星會製造有 足趣味外形 ê 星雲。 這是因為伊有足強 ê 恆星風,會 kā 邊仔 ê 星際物質掃開。 Tī 這个案例內底,這个足光 ê 雲邊可能是恆星犁過一个齊齊 ê 物質產生 ê 弓形衝擊,to̍h 親像是船行過水面仝款。 毋閣 測量 ê 結果 顯示,這个恆星並無直接徙去到較光彼爿。 所以上有可能 ê 解說是講,tī 恆星邊仔 ê 物質並無齊齊。 實際上,去予風吹 ê NGC 3199 較光彼爿,是一簇一簇、較密 ê。

[English] Windblown NGC 3199

NGC 3199 lies about 12,000 light-years away, a glowing cosmic cloud in the nautical southern constellation of Carina. The nebula is about 75 light-years across in this narrowband, false-color view. Though the deep image reveals a more or less complete bubble shape, it does look very lopsided with a much brighter edge along the top. Near the center is a Wolf-Rayet star, a massive, hot, short-lived star that generates an intense stellar wind. In fact, Wolf-Rayet stars are known to create nebulae with interesting shapes as their powerful winds sweep up surrounding interstellar material. In this case, the bright edge was thought to indicate a bow shock produced as the star plowed through a uniform medium, like a boat through water. But measurements have shown the star is not really moving directly toward the bright edge. So a more likely explanation is that the material surrounding the star is not uniform, but clumped and denser near the bright edge of windblown NGC 3199.
