Nuclei in the Cosmos XII - Satellite Workshop

In this contribution, we give overview about a current status of multidimensional radiation hydrodynamic simulations of core-collapse supernovae. In addition to 3D hydrodynamics and general relativity, both of which are now considered as the most important ingredients for making successful explosions, we discuss also impacts of nuclear equations of state on the supernova dynamics. We...

The problem of astrophysical site(s) for the r-process is still shrouded in mystery despite more than a half century of studies. Although neutrino driven winds have been considered to be the most likely success, recent state of the art hydrodynamic simulations show that it is seriously difficult to achieve suitable conditions for $r$-process by that scenario. We are reinvestigating the other...

The classical (n,gamma)-(gamma,n) phase of r-process nucleosynthesis is well understood. Less well understood is the complex freezeout phase during which the last of the free neutrons are consumed. I present some calculations using simplified nuclear physics to help characterize the r-process freezeout.
