Supernova Neutrino Process and its Impact on the Galactic Chemical Evolution of the Light Elements
Takashi Yoshida, Toshitaka Kajino
In order to resolve the overproduction problem of 11B in supernova explosions during Galactic chemical evolution, the dependence of the ejected masses of the light elements produce…
Constraining the Primordial Magnetic Field from Cosmic Microwave Background Anisotropies at Higher Multipoles
D. G. Yamazaki, K. Ichiki, T. Kajino
The cosmological magnetic field is one of the important physical quantities which affect strongly the cosmic microwave background (CMB) power spectrum. Recent CMB observations have…
Evidence for nucleosynthesis in supernova -process: Universal scaling on p-nuclei
T. Hayakawa, N. Iwamoto, T. Shizuma +3
With analyzing the solar system abundance, we have found two universal scaling laws concerning the p- and s-nuclei. They indicate that the gamma-process in supernova (SN) explosion…
Constraints on Resonant Particle Production during Inflation from the Matter and CMB Power Spectra
G. J. Mathews, D. J. H. Chung, K. Ichiki +2
We analyze the limits on resonant particle production during inflation based upon the power spectrum of fluctuations in matter and the cosmic microwave background. We show that suc…
Spectroscopic Studies of Extremly Metal-Poor Stars with Subaru/HDS:II.The r-process Elements, Including Thorium
S. Honda, W. Aoki, T. Kajino +5
We present the abundance analyses for the neutron-capture elements, and discuss the observed abundance distributions in very metal-poor stars with excesses of r-process elements. A…
Spectroscopic Studies of Extremely Metal-Poor Stars with Subaru/HDS:I. Observational Data
S. Honda, W. Aoki, H. Ando +14
We have obtained high-resolution (R 50,000 or 90,000), high-quality (S/N $\ga$ 100) spectra of 22 very metal-poor stars ([Fe/H] $\la$ -2.5) with the High Dispersion Spectr…
