Topic 14 - Stellar Evolution:

• Be able to use the Messier and New General Catalogue (NGC) in cataloguing nebulae, clusters and galaxies
• Be able to use the Bayer system for naming the brightest stars within a constellation
• Understand the effects of the interaction between radiation pressure and gravity in a main sequence star
• Understand changes to the radiation pressure-gravity balance at different stages in the life cycle of a star with a mass similar to the Sun
• Understand the balance between electron pressure and gravity in a white dwarf star
• Understand changes to the radiation pressure-gravity balance at different stages in the life cycle of a star with a mass much greater than the Sun
• Understand the balance between neutron pressure and gravity in a neutron star
• Understand the effect the Chandrasekhar Limit has on the outcome on the final stages of the life cycle of a star
• Understand the principal stages and timescales of stellar evolution for stars of similar mass to the Sun, including:
🡒 emission and absorption nebula
🡒 main sequence star
🡒 planetary nebula
🡒 red giant
