... Measuring the Stars How big are stars? How far away are they? How bright are they? How hot? How old, and how long do they live? What is their chemical composition? How are they moving? Are they isolated or in clusters? By answering these questions, we not only learn about stars, but about the struc ...

Eventually, it reaches a critical mass and nuclear fusion begins. • Begins the main sequence phase of the star • Most ...

... In last lecture, we saw a Type II supernova blowing off its outer layers in a gigantic explosion, due to a shock wave that bounced off the central neutron core. The supernova lights up the sky and seeds the neighborhood with heavy elements used for complex life. What’s left of the star after the exp ...
