天体尺度上的重大灾变事件——恒星的形成和归宿(下)

Major Catastrophes on the Scales of Celestial Objects——The Formation and Fate of Stars:Part 2

恒星之一生,长者可达几万亿年,短则不到一千万年,期间历经多次短时标的灾变事件,而此类事件出现前后,恒星多方面性质发生了非常剧烈的、甚至是根本性的改变。对此,天文学家已经有了较为充分的认识,但尚未完全洞悉其中之众多奥秘。

It is briefly introduced in this paper how white dwarfs, neutron stars or black holes can be finally produced through col- lapse process of cvolvcd stars with different masses, and what are the main physical and structural characteristics of these kinds of ce- lestial compact objects. Besides, some serious influences of stellar catastrophes on our planet, the earth, and human being lived on it that will probably occur in future are discussed.
