The Structure of Magnetic Herbig―Haro Jets

摘要

We present simulations of magnetized Herbig-Haro flows of low-mass stars. These slightly overdense jets propagate with about 300 km/s through the inner part of a molecular cloud. The magnetic field is injected from the central star and evolves a complicated time dependent structure driven by pinch and kink modes. The high spatial resolution achieved on the NEC SX―5 provides for the first time insight into the phenomenon of current filamentation and the complex internal structure of pinch and kink modes.
