Rationale

The systematic observational hunt for electromagnetic transients has revealed a growing diversity of supernova types and explosion-related phenomena. Progenitor searches have succeeded in identifying an increasing number of supernova progenitors and progenitor candidates, beginning to bridge the gap between massive star evolution and final stellar deaths as single stars and in binaries. Multi-wavelength studies of supernova remnants have collected an amazing wealth of precious data about the hydrodynamic and nucleosynthetic fingerprints left by the blast wave of the explosion. The computational modeling of supernovae and of the latest stages of progenitor evolution has become feasible in three spatial dimensions, and our theoretical picture of the neutrino-driven mechanism and of its consequences is on the way to mature.

While the progress in each area is remarkable, the accelerating inflow of observational data has posed more new riddles not only for the rare outliers of the stellar death events, than it was able to solve. Tying the many loose ends together will require the close(r) interaction of modelers and observers of progenitor stars, supernovae, and supernova remnants. Only then it will be possible to draw the right conclusions and to find answers for some of the most nagging astrophysical questions, for example:

• What are the explosion mechanisms of massive stars?
• How does binary evolution affect the stellar death?
• What is the fraction of black-hole forming cases?
• What is the fundamental systematics behind the growing zoo of supernova-like events?
• What is the role of stellar rotation and magnetic fields?
• How can the properties of the compact remnants of stellar core collapse be explained?

This workshop was intended to foster the interaction of the mentioned communities and follows up a similar, productive meeting at Chicheley Hall in June 2016.

Venue

The workshop was held at Ringberg Castle, 50 km south of Munich. It offers full-board accommodation and an inspiring atmosphere for intense communication, particularly fruitful for workshops.
