  1. Because of gravitational attraction, the escape velocity at the surface of a star, say, will be higher if the star is smaller in size or heavier

    恆星質量越大，體積越小，引力的羈絆便越大，所需逃逸速度亦越高。
  2. A quantitative analysis of this idea led to the prediction that a star remaining about three times the mass of the sun at the end of its evolution ( usually as a neutron star ), will almost inevitably shrink to the critical size needed to undergo a gravitational collapse

    該想法的定量分析導致預言一顆恆星在終止它演化時候保持大約三倍太陽的質量（通常看做一顆中子星） ，將會幾乎不可避免收縮到臨界體積必須遭受引力坍塌。
  3. Decades of observations have established that stars form within so - called molecular clouds : vast agglomerations of cold gas and dust, each with enough material to form scores of suns

    在累積了數十年的觀測結果之後，一般相信恆星是在所謂的分子云中形成：在遼闊的冷氣體與塵埃凝聚區域，每朵分子云都擁有足以形成許多太陽核心的材料。
  4. A million stars are crammed into a volume a few dozen light - years across ; an equivalent volume near the sun would accommodate only a hundred stars

    球狀星團在直徑幾十光年的體積內，塞入了100萬顆恆星；而太陽附近同等大小的體積內，卻只有100顆恆星。
  5. The conditions in a protostar resemble far more closely in situation in red giants, most of whose volume is caught up in stormy convection.

    原恆星的條件更加類似於紅巨星的情形，紅巨星體積的大部分都捲入劇烈的對流中。
  6. The luminosity per surface area will increase because the temperature increases. but if a star is not very massive, its luminosity will drop because the size of the star protostar decreases much faster

    每單位面積的光度會隨著恆星的溫度增加而上升，但假若恆星原恆星質量不足，它的光度會由於星體體積下降過速而不升反減。
  7. It ' s customary among the stars to quietly burn the hydrogen they are made of, generously giving energy to the void, until they are reduced to a dignified thinness and end their career as modest white dwarfs

    恆星，慣常是安靜的燃燒組成它們本身的氫，向空間里散發能量，直到達到一定的體積大小，它們作為白矮星的一生就抵達終點。
  8. Looking for planets orbiting red dwarfs is easier because the stars are less massive

    尋找圍繞紅矮星運轉的行星則相對容易，因為恆星的體積較小。
