[Astronomy seminar] Astronomy seminar via zoom, 20 November 10:30: Jérôme Guilet

[Astronomy seminar announcements]

Dear all,

On Friday November 20 at 10:30 we will have the next Astronomy Seminar, remotely via zoom.

Our speaker is Jérôme Guilet from the CEA Saclay, Paris.

Title: Magnetar formation & extreme explosions.

Abstract: Extremely strong magnetic fields of the order of 10^15 Gauss are required to explain the properties of magnetars, the most magnetic neutron stars. Such a strong magnetic field is expected to play an important role for the dynamics of core-collapse supernovae, and in the presence of rapid rotation may power superluminous supernovae and hypernovae associated to long gamma-ray bursts. The origin of these strong magnetic fields is still uncertain and most likely requires an amplification over several orders of magnitude in the protoneutron star. I will review our current understanding of the physical processes that can lead to this magnetic field amplification, including the magnetorotational instability and the convective dynamo. I will also describe how the explosion dynamics depends on the properties of the magnetic field.
