Supernova 1987A: neutrino-driven explosions in three dimensions and light curves / First access to the "r-process path"

Monday 9 Feb 2015, 13:00 → 14:00 Asia/Tokyo

RIBF Bldg. 2F, Room 203 (RIKEN Wako)

Date: Monday, Feb. 9th, 13:00- Place: Room 203, RIBF building Title: Supernova 1987A: neutrino-driven explosions in three dimensions and light curves Speaker: Dr. Annop Wongwathanarat (ABB Lab) Abstract: SN1987A is one of the most well-studied core-collapse supernova explosions which happened in the Large Megellanic Cloud on Feb 23, 1987. For more than two decades this spectacular event has received great interests from astrophysicists as a unique case for studying the explosion mechanism of core-collapse supernovae. In this talk, I will summarize latest results from state-of-the-art 3D simulations of neutrino-driven core-collapse supernovae and 1D calculations of light curves from these models. These results show how we can gain insightful information about the progenitor star of SN198A by comparison of simulation results with data from observations. Title: First access to the "r-process path" Speaker: Dr. Tohru Motobayashi (RIKEN Nishina Center) Abstract: Now the opportunity opens up, for the first time, to us to visit r-process nuclei in the laboratory. The RIKEN RI Beam Factory (RIBF) was designed to have access, by its radioactive isotope (RI) beams, to nuclei very far from the stability valley, covering a large part of the "r-process path". Experimental studies of their beta-decays, which are important in astrophysical network calculations to simulate nucleosynthesis, have started. In addition to the recent results, I will discuss on new experimental information expected to be provided in the near future. ---- Dear Colleagues, This is the reminder of the ABB & TNP joint group sminar next Monday (Feb 9 th) from 13:00 @ Room 203, RIBF building. We will have two 15+10 introductory talks by Dr. Tohru Motobayashi and Dr. Annop Wongwathanarat, respectively. Best regards,
