ASTA02H3 Lecture Notes - Thermostat, Brown Dwarf, Ideal Gas
Document Summary
Clumped areas of ism stellar nursery ( clump in nebula) low temperature. Must have be triggered by a mechanism this mechanism usually comes in form of a shock wave. A sudden change in pressure that travels as an intense sound wave triggered by. Arms push and compress gas (similar to food processor) Movement of particles thermal energy opposes gravity. A collapsing cloud of gas doesn t form just two stars. A group of stars that are formed together. Not visible because lots of dust lower temperatures mean longer. When matter is compressed, energy is released (thermal energy) Collapse continues because as long as heat is released of the heat heats up the core of the heat is released. An increase in density leads to an increase in opacity. Opacity resistance of gas to the passage of radiation. Molecule, pressure if volume is held constant. Temperature controls pressure temperature rises in the center.
