The more massive the protostar, the more rapidly it evolves
{"Image DocumentName": "The more massive the protostar, the more rapidly it evolves", "Image ImageDescription": "Greater mass, contracts and heats more rapidly, and hydrogen fusion begins earlier. Greater mass, greater pressure and temperature in the core. If protostar less than 0.08 Msun, it can never develop the temperature and pressure to start the hydrogen fusion. Such failed stars end up as brown dwarfs, which shines faintly by Kelvin-Helmholtz contraction.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
