白矮星的意思、翻譯和例句

是什麼意思

「白矮星」是指一種小型的、已經耗盡核燃料的恆星，通常形成於中等質量恆星（如太陽）在其生命週期結束後的演化過程中。白矮星的質量通常與太陽相當，但體積卻非常小，密度極高，主要由電子簡並物質組成。白矮星的光輻射主要來自其殘餘的熱量，隨著時間推移，這些恆星會逐漸冷卻並變暗。

1：White Dwarf

用法：

白矮星是恆星演化過程中的一個階段，通常是中等質量恆星（如太陽）在其燃料耗盡後的結果。這種星體的質量與太陽相近，但體積卻非常小，並且其表面溫度極高，隨著時間推移會逐漸冷卻。白矮星的形成過程涉及恆星外層的脫落，留下核心部分，這個核心部分就是白矮星。白矮星的研究對於理解恆星的演化和宇宙的結構有重要意義。
