Nucleosynthetic signatures of the first stars
Anna Frebel, Wako Aoki, Norbert Christlieb +16
The chemically most primitive stars provide constraints on the nature of the first stellar objects that formed in the Universe; elements other than hydrogen, helium and traces of l…
Cosmological Nucleosynthesis in the Big-Bang and Supernovae
Toshitaka Kajino
Recent observation of the power spectrum of Cosmic Microwave Background (CMB) Radiation has exhibited that the flat cosmology is most likely. This suggests too large universal bary…
s-Process Nucleosynthesis in Low-Metallicity Stars
Nobuyuki Iwamoto, Toshitaka Kajino, Grant J. Mathews +2
We have made a parametric study of s-process nucleosynthesis in the metal poor ([Fe/H]=-2.7) stars LP625-44 and LP706-7. We find that a high neutron exposure and a small overlap fa…
Impact of Few-Body Reactions on Explosive Nucleosynthesis: The Big-Bang and Supernovae
Toshitaka Kajino, Kaori Otsuki, Shin-ya Wanajo +2
We study the few body reactions in explosive nucleosynthesis of light-to-heavy mass elements in various astrophysical conditions. In neutrino-driven winds of gravitational core col…
New Detremination Method of Primordial Li Abundance
T. Kajino, T. -K. Suzuki, S. Kawanomoto +1
We discuss the primordial nucleosynthesis in lepton asymmetric Universe models. In order to better estimate the universal baryon-mass density parameter , we try to remove the…
Neutrino Degeneracy and Decoupling: New Limits from Primordial Nucleosynthesis and the Cosmic Microwave Background
M. Orito, T. Kajino, G. J. Mathews +1
We reanalyze the cosmological constraints on the existence of a net universal lepton asymmetry and neutrino degeneracy. We show that neutrinos can begin to decouple at higher tempe…
