At the average density of a star-forming molecular cloud, about 900 atoms per cm3, determine how large a sphere you would need to encompass mass equal to that of the Sun? Enter the radius of this sphere in light-years. (HINTS: 900 atoms per cm3 corresponds to a density of 1.51×10-18kg/m^3; the mass of the Sun is 2×1030kg) (The volume of a sphere is 4/3 * π * R3) (my previous answer of 6.812 X 1015 was incorrect)
Using a Hertzsprung–Russell diagram to illustrate your answer, describe in detail the followingmain stages of a solar mass star’s evolutionary track. You should briefly describe the importantphysical process/processes at each stage, and one or two observational facts.• protostar• main-sequence• post-main-sequence
what is a star? define neclear fusion? how does nuclear fusion keep the star keep burning ?
