Death of Massive Stars : Chapter Sixteen : Nature of the UniverseKwongSang ChengHoiFung ChauKaiMing Lee
MASSIVE stars undergo violent deaths, forming the type II supernovae believed to result from gravitational collapse of the stellar cores. Such an event may be recognised by the optical outburst which occurs when the thermal and kinetic energy generated by the collapse propagates to the stellar ...

time, they can be recycled to make something different. For example, every atom in our bodies was once part of something else. Over time, rocks can become living things and living things, following their demise, can become fossilized rocks. What's true for us is also true for the stars....
really massive stars are rare (seeThe Stars: A Celestial Census). This is similar to the music business where only a few musicians ever become superstars. Furthermore, many stars with an initial mass much greater than 1.4MSunwill be reduced to that level by the time they die. For example...
Death of Massive Stars As iron core grows, the immense weight is supported by electron degeneracy pressure--ie, electron gas Eventually the electron gas is compressed to the point that the electron degeneracy pressure is overcome by gravity--electrons combine with protons forming neutrons and emittin...

Suppose no stars more massive than about 2 MSun had ever formed. Would life as we know it have been able to develop? Why or why not? Would you be more likely to observe a type II supernova (the explosion of a massive star) in a globular cluster or in an open cluster? Why? Astron...
During their lives, massivestars cause helium nuclei to join together to make oxygen.Then, when the stars explode, they cast this oxygen intospace. And the explosions themselves make iron. In fact,scientists think supernova explosions made most of the ironin the universe. So even though a ...
