We investigate the impact of strong initial magnetic fields in core-collapse supernovae of non-rotating progenitors by simulating the collapse and explosion of a 16.9 Msun star for…
Stripped-envelope stars in different metallicity environments. II. Type I supernovae and compact remnants
David R. Aguilera-Dena, Bernhard Müller, John Antoniadis +4
Stripped-envelope stars can be observed as Wolf-Rayet (WR) stars, or as less luminous hydrogen-poor stars with low mass loss rates and transparent winds. Both types are potential p…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814

State-of-the-art numerical simulations of core-collapse supernovae reveal that the main source of gravitational waves is the excitation of proto-neutron star modes during post-boun…
