PHYS 183 Lecture Notes - Electron Degeneracy Pressure, Protostar, Main Sequence
Document Summary
We think that the milky way collapsed into a disk; our solar system is a disk. When you have a disk you have solar jets that come out of it in opposite directions. We don"t know how these things form, but many think it may be due to magnetic fields that shoot materials out jets are tight beams of material like electrons that shoot at the speed of light. We don"t understand the distribution of different masses along the hr diagram. Massive stars are rare for every 1 very massive star, you have 200 stars less massive than the sun (nobody knows why yet) Electron degeneracy pressure the laws of quantum mechanics prohibit two electrons from occupying the same state in the same place. Phys 183 the milky way inside and out tracy webb. Brown dwarfs are failed stars: electron degeneracy pressure halts the collapse before fusion can begin for mass < 0. 08.
