Abundances in Metal-Poor Stars and Chemical Evolution of the Early Galaxy
G. J. Wasserburg, Y. -Z. Qian
We have attributed the elements from Sr through Ag in stars of low metallicities ([Fe/H] < -1.5) to charged-particle reactions (CPR) in neutrino-driven winds, which are associated…
Recent Progress in the Understanding of the r-Process
Yong-Zhong Qian
A brief overview of the r-process is given with an emphasis on the observational implications for this process. The conditions required for the major production of the heavy r-proc…
Stepwise Spectral Swapping with Three Neutrino Flavors
Huaiyu Duan, George M. Fuller, Yong-Zhong Qian
We develop a framework for studying collective three-flavor neutrino oscillations based on the density matrix formalism. We show how techniques proven useful for collective two-fla…
Flavor Evolution of the Neutronization Neutrino Burst from an O-Ne-Mg Core-Collapse Supernova
Huaiyu Duan, George M. Fuller, J. Carlson +1
We present results of 3-neutrino flavor evolution simulations for the neutronization burst from an O-Ne-Mg core-collapse supernova. We find that nonlinear neutrino self-coupling en…
Neutrino Mass Hierarchy and Stepwise Spectral Swapping of Supernova Neutrino Flavors
Huaiyu Duan, George M. Fuller, J. Carlson +1
We examine a phenomenon recently predicted by numerical simulations of supernova neutrino flavor evolution: the swapping of supernova and energy spectra below (abov…
Simple Picture for Neutrino Flavor Transformation in Supernovae
Huaiyu Duan, George M. Fuller, Yong-Zhong Qian
We can understand many recently-discovered features of flavor evolution in dense, self-coupled supernova neutrino and antineutrino systems with a simple, physical scheme consisting…
