Self-gravity plays a decisive role in the final stages of star formation, where dense cores inside molecular clouds collapse to form star-plus-disk systems. But the role of self-gravity at earlier times is unclear. This paper reports a dendogram analysis that reveals that self-gravity plays a significant role over the full range of scales traced by 13CO observations in L1448, but not everywhere in the observed region.
