  1. Life Cycle of Stars Revision lecture Lecture slides available in powerpoint and pdf from www.star.le.ac.uk/~mbu/lectures.html

  2. Everything taught in the course is examinable….. • However, here is a crib sheet of what to focus on

  3. Lifecycles of Stars • Unit 1 - Observational properties of stars • Flux, intensity and luminosity • Stellar magnitudes and photometry • Temperatures masses and radii • Unit 2 - Stellar Spectra • Absorption and emission processes • Atmospheric opacity • Spectral classification of stars • Hertzsprung-Russell diagram • Unit 3 - The Sun • Unit 4 - Stellar Structure • Unit 5 - Stellar Evolution • Unit 6 - Stars of particular interest

  4. Unit 3 – The Sun • Basic physical parameters • Structure of interior and atmosphere • Surface features • Magnetic field • Solar activity, flares and pulsations

  5. Unit 4 – Stellar Structure • Hydrostatic equilibrium • Equations of state • Energy transport & sources • Eg PPI chain • Luminosity relation • Eddington Limit

  6. Unit 5 – Stellar Evolution • Star formation • Main sequence • Stellar clusters (open, globular) • Population I & II stars • Red Giants • Planetary Nebulae • White Dwarfs • Supernovae • Neutron Stars

  7. Stars of Particular Interest • Binaries – visual, spectroscopic, eclipsing • Variable stars • Active/interacting binaries (Novae) • Stellar pulsations • Cepheid variables and the distance scale
