Supergiant - Study guides, Class notes & Summaries

What happens to a low mass star after spending most of its life on the main sequence? - It evolves to the red giant region of the H-R diagram. Which two ways can a star generate energy? - Fusion reactions in the core of the star and gravitational contraction. How does a main sequence star become a red giant? - When H in the core is exhausted, there is no more energy generation and gravity takes over, so the He core and the surrounding H shell contract. This leads to H-fusion due to the hea...

Big Bang theory the theory that the universe was created in a massive explosion (the Big Bang), and that the universe has been expanding ever since black dwarf a star that has faded out and gone cold black hole an object in space that has so much mass that nothing, not even light, can escape from its gravitational field centripetal force the resultant force towards the centre of a circle acting on an object moving in a circular path cosmic microwave background rad...

AQA GCSE Physics 4.8 - Space Physics Already Passed Nucleus The central part of an atom, containing protons and neutrons. Main sequence star A star during the main part of its life cycle, where it is using hydrogen as a fuel. Black hole The core of a red supergiant that has collapsed. These are formed if the remaining core has a mass more than three or four times the mass of the Sun. It is so dense that light can't escape it. Protostar The earliset stage in the lifecycle of a star They are f...
