Schematic view of the physical components in an embedded Stage 0 or I young stellar object: a passively heated envelope (yellow, with a hot core shaded red), a bipolar jet (green, with bow shocks and internal working surfaces), UV-heated outflow cavity walls (red), and small-scale shocks along the cavity walls (blue). Not visible on this scale is an embedded circumstellar disk with a radius of  ~100 AU.
