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。Evolution of stars of all masses takes place on a hydrodynamic time scale.
各種質量的恆星的演化,均以流體力學的時間尺度進行。From long ago, by an established tradition that can be traced to the hypothesis of immanuel kant and the marquis de laplace, astronomers have assumed that stars develop out of a scattered, diffuse medium of gas and dust.
很長時間以來,天文學家承襲了可以追溯至康德和拉普拉斯假說所建立的概念,認為恆星由散布在空中的彌漫氣塵物質演變而來。When the star becomes hot enough, it ionizes its surrounding gas from which the dust has been expelled.
