Lecture 15 PHYS1005 – 2003/4
Lecture 16: Stellar Structure and Evolution – I
Objectives:• Understand energy transport in stars• Examine their internal structure• Follow their evolutionary paths in H-R diagram
Energy Transport in Stars:
• Sun’s TC = 15 million K, TS = 5800 K• energy (heat) must flow from core surface
