Supernovae as the Site of the r-Process: Implications for Gamma-Ray Astronomy
Y. -Z. Qian, P. Vogel, G. J. Wasserburg
We discuss how detection of gamma-ray emission from the decay of r-process nuclei can improve our understanding of r-process nucleosynthesis. We find that a gamma-ray detector with…
Diverse Supernova Sources for the r-Process
Y. -Z. Qian, P. Vogel, G. J. Wasserburg
(Abridged) It is shown that a semi-quantitative agreement with the gross solar r-process abundance pattern near and above mass number A=130 can be obtained by a superposition of tw…
Comment on "Pulsar Velocities and Neutrino Oscillations"
Y. -Z. Qian
In a recent Letter, Kusenko and Segre proposed a new mechanism to explain the observed proper motions of pulsars. Their mechanism was based on the asymmetric neutrino emission indu…
Neutrino-induced nucleosynthesis and the site of the r-process
W. C. Haxton, K. Langanke, Y. -Z. Qian +1
If the r-process occurs deep within a Type II supernova, probably the most popular of the proposed sites, abundances of r-process elements may be altered by the intense neutrino fl…
Neutrino-nucleus interaction and supernova r-process nucleosynthesis
Y. -Z. Qian
We discuss various neutrino-nucleus interactions in connection with the supernova r-process nucleosynthesis, which possibly occurs in the neutrino-driven wind of a young neutron st…
Resonant Neutrino Spin-Flavor Precession and Supernova Nucleosynthesis and Dynamics
H. Nunokawa, Y. -Z. Qian, G. M. Fuller
We discuss the effects of resonant spin-flavor precession (RSFP) of Majorana neutrinos on heavy element nucleosynthesis in neutrino-heated supernova ejecta and the dynamics of supe…
Matter-enhanced antineutrino flavor transformation and supernova nucleosynthesis
Yong-Zhong Qian, George M. Fuller
Matter-enhanced antineutrino flavor transformation between and can occur in supernovae if the vacuum masses for these species satisfy $m_{\barν_e}>m_{\barν…
Neutrino-Neutrino Scattering and Matter-Enhanced Neutrino Flavor Transformation in Supernovae
Yong-Zhong Qian, George M. Fuller
We examine matter-enhanced neutrino flavor transformation () in the region above the neutrino sphere in Type II supernovae. Our treatment explicitly…
