ASTR 1101 Lecture Notes - Kipper, Dust Bunny
Document Summary
Order of solar system: terrestrials, asteroid belts, jovians, kipper belt, orrt cloud. Stellar nurseries: cold temp, high density, dust! Stars can produce iron in core: death rows- stars go through a thermal blast. All metals get blown out into space: supernova is the only thing powerful in nature to produce all elements (specifically everything heavier than iron, stars doing regular business produce all elements up to iron. Elements in the sun: carbon comes from dead stars, so basically we are made of dead star stuff. Then the cloud has to be disrupted in some way. ** a super nova is why our nebula collapsed to create our solar system. Element: can have specific # of protons, neutrons change create isotope. Radioactive- an isotope that breaks down into something else. When the nursery collapse- gravity pulls everything in at an angle- formed into a star. Evidence that universe formed by a disk: planets orbit in the same direction and same screen.
