Description

This unit introduces the physics underlying the structure and evolution of stars, through a description of applicable nuclear physics, fluid mechanics and thermal physics.

Emphasis is placed on deriving simple models for the structures of different types of star and the processes of stellar evolution.

Aims:

  • To introduce the physics that underlies the behaviour and evolution of stars, and show how these physical processes lead to stability of normal stars and the instability of some special types of stars including supernovae.
  • To relate the physics of the energy generation mechanisms in stars to terrestrial fusion experiments.
  • To explore how stars process primordial material into elements that are common in the Universe today.

Intended learning outcomes

Able to use the virial theorem and equations of hydrostatic equilibrium. Understand the importance of equations of state. Understand the different effects and environments of the r and s processes in nucleosynthesis. Understand the radiative and convective transfer of heat. Understand the ythe origins of the chemical elements. Understand how the different masses of stars lead to different endpoints of stellar evolution.
