<div class=""><span class="" style="font-size: 14px;">On Friday November 20 at 10:30 we will have the next Astronomy Seminar, remotely via zoom.</span></div>
<div class=""><span class="" style="font-size: 14px;"><br class="">
</span></div>
<div class=""><span class="" style="font-size: 14px;">Our speaker is Jérôme Guilet from the CEA Saclay, Paris.</span></div>
<div class=""><span class="" style="font-size: 14px;"><br class="">
</span></div>
<div class=""><span class="" style="font-size: 14px;">Title: Magnetar formation & extreme explosions.</span></div>
<div class=""><span class="" style="font-size: 14px;"><br class="">
</span></div>
<div class=""><span class="" style="font-size: 14px;">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. </span></div>
