The Vigorous Afterlife of Stars:
From Gamma-Ray Bursts to Accreting Black Holes and Neutron Stars Kristen Menou Institut d'Astrophysique de Paris abstract From gamma-ray burst afterglows to radiatively-inefficient accreting black holes and anomalously-powered X-ray pulsars, several new manifestations of the afterlife of massive stars have emerged over the past few years. I will review recent observational breakthroughs in stellar high-energy astrophysics and highlight key theoretical issues that remain to be addressed. The combination of differential rotation and magnetic fields is, arguably, one of the most important physical ingredients, common to all these manifestations. |
