Description

We present a model for the Type Ib SN 2008D, associated with the X-ray Flash 080109, which assumes a double-peaked 56Ni distribution. This assumption is fundamental to explain the plateau observed in the light curve a few days after the explosion. The presence of this high-velocity radioactive material may be caused by the formation of jets during the explosion. We briefly discuss the alternative scenarios that have been suggested for this supernova.
