[漢羅] 恆星風製造 ê 星雲 RCW 58

咱來想像一下，咱來到一粒 100 倍 太陽質量、1 百萬倍太陽光度、30 倍太陽表面溫度 ê 恆星。 這款恆星叫做 Wolf Rayet 星 (嘛叫做 WR 星)，是法國天文學家 Charles Wolf kah Georges Rayet kā 號名--ê。 這張相片中心 ê 恆星 WR 40 就是這款星，伊就 tī 船底座遐。 WR 40 kah 咱 ê 太陽 相比，伊燒較緊，嘛較緊死。 In 足緊就 kā 核心 ê 水素 用了了，紲落來 繼續 tī 核心進行 較重元素 ê 核融合，落尾會利用高速 恆星風 kā 外層氣體捒出去。 以 WR 40 ê 例來講，伊 kā 伊 ê 大氣 用 1 秒鐘 100 公里緊 ê 速度 捒出去，這寡外層氣體落尾就變做湠開 ê 卵形星雲 RCW 58。

[English] Stellar Wind-Shaped Nebula RCW 58

Imagine traveling to a star about 100 times as massive as our Sun, a million times more luminous, and with 30 times the surface temperature. Such stars exist, and some are known as Wolf Rayet (WR) stars, named after French astronomers Charles Wolf and Georges Rayet. The central star in this image is WR 40 which is located toward the constellation of Carina. Stars like WR 40 live fast and die young in comparison with the Sun. They quickly exhaust their core hydrogen supply, move on to fusing heavier core elements, and expand while ejecting their outer layers via high stellar winds. In this case, the central star WR 40 ejects the atmosphere at a speed of nearly 100 kilometers per second, and these outer layers have become the expanding oval-shaped nebula RCW 58.
