| | 71 | This all shows us that '''the majority of energy gains from a stellar source occurs very close to the source''', and thus, using the equation of accretion luminosity for a particle starting from rest at infinity is a fine approximation over many length scales (i.e. only breaks down once your cell size gets very small, because then the gas will not have traveled very far until it hits the stellar surface). As a caveat, the sink is so much less then a cell size and has no radius. Thus, these are all upper limits to the resolution requirements. |
