Three-dimensional core-collapse supernovae with complex magnetic structures: I. Explosion dynamics

2021

Magnetic fields can play a major role in the dynamics of outstanding explosions associated to violent events such as GRBs and hypernovae, since they provide a natural mechanism to harness the rotational energy of the central proto-neutron star and power relativistic jets through the stellar progenitor. As the structure of such fields is quite uncertain, most numerical models of MHD-driven core-collapse supernovae consider an aligned dipole as initial magnetic field, while the field's morphology can actually be much more complex. We present three-dimensional simulations of core-collapse supernovae with more realistic magnetic structures, such as quadrupolar fields and, for the first time, an…

The impact of non-dipolar magnetic fields in core-collapse supernovae

2019

The magnetic field is believed to play an important role in at least some core-collapse supernovae if its magnitude reaches $10^{15}\,\rm{G}$, which is a typical value for a magnetar. In the presence of fast rotation, such a strong magnetic field can drive powerful jet-like explosions if it has the large-scale coherence of a dipole. The topology of the magnetic field is, however, probably much more complex with strong multipolar and small-scale components and the consequences for the explosion are so far unclear. We investigate the effects of the magnetic field topology on the dynamics of core-collapse supernovae and the properties of forming proto-neutron star (PNS) by comparing pre-collap…

Structuration du territoire bourguignon : de l'île à l'isthme

2006

Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
