  1. Pulsating variables vary periodically, but for some stars, there may be sudden changes in their brightness. such kinds of stars are called eruptive variables. they include

    ：脈動變星的光度會周期性地改變，但有一些恆星的光度會在毫無先兆下變得光芒萬丈，這種恆星包括新星和超新星皆統稱為爆發變星。
  2. Since the hydrogen - burning shell and helium - burning core do not produce energy in a stable and steady manner, the star will pulsate and generate strong stellar wind

    由於這時燃燒氫和氦以產生能源的過程並不穩定，星體除了會不斷脈動外，更會產生強勁的恆星風把外殼吹掉。
  3. Their shells, which apart from hydrogen, helium, and carbon also contain portions of the heavy elements formed in the stellar core, are inherently unstable, and their pulsing creates a withering stellar wind a billion times stronger than the solar wind we know today

    它的殼層除了氫層、氦曾和碳層外還有包含一部分產生自恆星核心的重元素，天生的不穩定，它們的脈動產生了一種毀滅性的星風，比我們現在知道的太陽風要強數百萬倍。
  4. To search for high - velocity molecular emission toward massive star formation regions, and to study the connections between h2o masers, iras objects and outflow properties, we carried out a co observation for a h2o maser sample. we found that most of the objects have excess high velocity emission produced by outflows ; we find a significant correlation between co line full widths and iras luminosities. the widths are proportional to the iras luminosities

    通過在大質量恆星形成區搜尋高速分子輻射，並且研究它們與星際h _ 2o脈澤源和所聯系的紅外源之間的關系，我們發現絕大多數源都存在著氣體的高速運動並且它們是由分子外流產生的；我們同時發現在co分子的譜線全寬和所對應源的紅外光度之間存在很好的相關性，線寬隨紅外光度增加而變大。
  5. Besides acting as powerful signposts of active star formation, the intense maser emission provides a unique tool to probe the physical conditions and kinematics of these regions on scales of 10 - 103 au

    星際脈澤不僅是恆星形成的一個及其重要的標志，而且也提供圍繞大質量恆星尺度10 - 10 ~ 3au分子氣體的物理條件和動力學結構的信息。
  6. Pulsating variables are stars that are continuously expanding and contracting and therefore show variations in brightness

    例如脈動變星就是恆星本身不斷膨脹收縮，造成光度亦出現相應的變化。
  7. Colliding black holes, collapsing stars, and spinning compact celestial objects such as pulsars create ripples in the fabric of space and time that subtly distort the world around us

    黑洞碰撞、恆星坍縮以及自旋脈沖星所激起的時空結構波動，微妙的扭曲了我們周圍的世界。
