Stellar Evolution

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• be able to solve order-of-magnitude problems on any part of the syllabus
• demonstrate clear insight into the underlying physical principles associated with all the key stages of stellar evolution from initial star formation within gas clouds in the Galactic plane, through the various stages of “stability,” to the final end products
• describe how astrophysics brings together all branches of physics and thus allows us to understand the ‘big picture’ of physics

• Overview of gravitational contraction and star formation, nucleosynthesis, virial theorem, stellar timescales.
• Properties of matter and radiation: Ideal gas, electron and neutron degeneracy, blackbody radiation, ionization.
• Heat transfer: Radiation transport, conduction, convection.
• Thermonuclear fusion: Barrier penetration, reaction rates, hydrogen and helium burning, neutrino emission.
• Stellar modelling: Equations of stellar structure, polytropes.
• Stellar death: Supernovae, white dwarfs, neutron stars, black holes.
