Special Relativistic Simulations of Magneto-driven Jet from Core-Collapse Supernovae |
Abstract _ |
From the observational fact, it is probable that gamma-ray bursts and core-collapse supernovae have same origin. And the very collimated jet is preferable to explain the light curve of their afterglow. The concern with the magneto-hydrodynamical process in core-collapse supernove has been grwoing because it could be the power of the collimated jet. However since the previous works are performed separately at each stage such as core-collapse and jet-propagation, many initial uncertainty remains in each stage. However we have performed the simulations from the magnetized core-collapse to the jet-propagation totally. This study gives us deeper knowledge on the relation between the profile of the jet and the progenitor. |
