Prof. Edo Berger (Harvard University)10/08/2011, 14:00Stars more massive than about 8 times the mass of the Sun end their lives in cataclysmic explosions: supernovae and gamma-ray bursts. In recent years targeted and blind transient surveys have expanded the range of potential outcomes, including potentially non-destructive eruptions on the path to the eventual explosion and highly-luminous events that may require a new range of progenitor...Go to contribution page

Mr Morgan Fraser (Queens University Belfast)10/08/2011, 14:30In the last fifteen years, searches for the progenitors of core-collapse supernovae in archival Hubble Space Telescope images have yielded progenitor candidates for ~10 nearby supernovae, and upper limits on the luminosity and mass for a further ~20. In this talk, I discuss recent results from ongoing progenitor searches. In particular, I focus on some of the open questions in progenitor...Go to contribution page

Dr Andrea Pastorello (Universita' di Padova)10/08/2011, 15:00A number of supernovae has been discovered in recent times showing weird observed properties. A few of them are extremely sub-luminous, others are among the brightest stellar explosions ever observed. In this review I present photometric and spectroscopic data of some of the most astonishing unusual transients, and outline what we currently know on the nature of their progenitor stars.Go to contribution page

Jesper Sollerman (Stockholm University)10/08/2011, 16:00I will make a quick review of the connection between Supernovae and Gamma-Ray Bursts, from an observers perspective. I plan to run through the history of GRBs with a special eye to the SN associations, and try to include also some of the more recent issues and developments.Go to contribution page

Prof. Alexander Heger (University of Minnesota, Twin Cities)10/08/2011, 16:30Recent progress in observations have allowed us to now find an overwhelming collection of observational supernova data including a wealth of different classes and marvelous detail in part. But how do they connect with our understanding of the underlying engine, and what stars are responsible for each of them? Theoretical models, on the other hand, also provides a wide variety of model,...Go to contribution page

Dr Avishay Gal-Yam (Weizmann Institute Of Science)10/08/2011, 17:00The theoretical prediction that stars that develop heavy oxygen cores will become pair-unstable and explode has been made many decades ago. Yet, for many years, no examples of such explosions were found, and it was often conjectured that stars massive enough to explode in this manner may only exist at very high redshifts (population III stars). In recent years several luminous supernova...Go to contribution page
