A) assume uniform, isothermal, non-rotating jeans collapse. what radius gas cloud would a browm dwarf of mass 0.07 solar masses and temperature 1000k form from? assume u=1
b) the smallest observed molecular clouds (blok globules) are approximately 1000 a. u. in radius, with a wide range in density and t. why is this a problem for part (a) above? what additional physics must the model include to allow brown dwarfs to form via gravitiational collapse? describe the chain of events.
