Edexcel GCSE (9-1) Astronomy, Topic 14: Stellar Evolution

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 🡒 white dwarf 🡒 black dwarf • Understand the principal stages and timescales of stellar evolution for stars of much larger mass than the Sun, including: 🡒 emission and absorption nebula 🡒 main sequence star 🡒 red giant 🡒 white dwarf 🡒 supernova 🡒 neutron star 🡒 black hole • Understand how astronomers study and gather evidence for the existence of black holes ⭐️ 𝗟𝗶𝗻𝗸𝘀 ⭐️ ☕️ Like what I'm doing?
