All the data plotted here is from this one star cluster, from a single moment in time. It shows that stars with more mass—and therefore more gravity—contract faster and have already begun to fuse atomic nuclei in their cores, earning them the distinction of “main sequence.” WebHerbig-Haro (HH) objects are the optical manifestations of this powerful mass loss. Analysis of HH flows, and in particular of the subset of highly collimated HH jets, provides indirect but important insights into the nature of the accretion and mass-loss processes that govern the formation of stars. how come i am not losing weight
