[漢羅] 逃走 ê 恆星 鹿豹座 α

逃走 ê 恆星 鹿豹座 α 就親像是一隻船行過宇宙海，tī 天頂製造出這款優美弧 ê 弓形波湧 抑是 弓形震波。 大質量 ê 超巨星 tī 天頂徙動 ê 速度，一秒鐘是超過 60 公里，結果就會 kā 伊行過 ê 路頂懸 ê 星際物質 櫼櫼做伙。 鹿豹座 α 差不多 tī 影像 中央 6 度闊 ê 範圍。 Kah 咱太陽相比，伊 ê 質量是 25 - 30 倍大，溫度是 5 倍燒 (3 萬 K)，光度是 50 萬倍光。 這粒 tī 4000 光年遠、長頷頸星座 鹿豹座 方向 ê 恆星，仝款會製造足強 ê 恆星風。 鹿豹座 α ê 弓形震波 kah 伊中心恆星 ê 距離 是差 10 光年遠。 是講，到底是啥物咧驅動這粒 恆星 ê 運動？ 天文學家長期以來攏認為講，鹿豹座 α 可能是 附近星團內底 ê 高溫少年恆星 kah 星團內底其他成員 產生重力交互作用，去予擲出來--ê 星。 嘛有可能是，伊 ê 大質量恆星 星伴，演化做超新星爆炸 ê 時陣，kā 伊擲出來--ê。

[English] Runaway Star Alpha Camelopardalis

Like a ship plowing through cosmic seas, runaway star Alpha Camelopardalis has produced this graceful arcing bow wave or bow shock. The massive supergiant star moves at over 60 kilometers per second through space, compressing the interstellar material in its path. At the center of this nearly 6 degree wide view, Alpha Cam is about 25-30 times as massive as the Sun, 5 times hotter (30,000 kelvins), and over 500,000 times brighter. About 4,000 light-years away in the long-necked constellation Camelopardalis, the star also produces a strong stellar wind. Alpha Cam's bow shock stands off about 10 light-years from the star itself. What set this star in motion? Astronomers have long thought that Alpha Cam was flung out of a nearby cluster of young hot stars due to gravitational interactions with other cluster members or perhaps by the supernova explosion of a massive companion star.
