Impacts of Hawking Radiation from Primordial Black Holes in Critical Collapse Model on the Light Element Abundances
Yudong Luo, Chao Chen, Motohiko Kusakabe +1
We study the photodisintegration process triggered by the nonthermal electromagnetic Hawking radiation from primordial black holes (PBHs) in critical collapse model. We consider th…
Screening Effects on Electron Capture Rates and Type Ia Supernova Nucleosynthesis
Kanji Mori, Toshio Suzuki, Michio Honma +4
Type Ia supernovae (SNe Ia) are believed to be a thermonuclear explosion of a white dwarf, but the mass of their progenitors is still an open problem. In near-Chandrasekhar-mass (n…
Enhancement of Lithium in Red Clump Stars by the Additional Energy Loss Induced by New Physics
Kanji Mori, Motohiko Kusakabe, A. Baha Balantekin +2
Since 7Li is easily destroyed in low temperatures, the surface lithium abundance decreases as stars evolve. This is supported by the lithium depletion observed in the atmosphere of…
Elimination of the Blue Loops in the Evolution of Intermediate-mass Stars by the Neutrino Magnetic Moment and Large Extra Dimensions
Kanji Mori, A. Baha Balantekin, Toshitaka Kajino +1
For searching beyond Standard Model physics, stars are laboratories which complement terrestrial experiments. Massless neutrinos in the Standard Model of particle physics cannot ha…
Nuclear Reaction Screening, Weak Interactions, and r-Process Nucleosynthesis in High Magnetic Fields
Michael Famiano, A. Baha Balantekin, Toshitaka Kajino +3
Coulomb screening and weak interactions in a hot, magnetized plasma are investigated. Coulomb screening is evaluated in a relativistic thermal plasma in which electrons and positro…
Explaining the Variations in Isotopic Ratios in Meteoritic Amino Acids
Michael A. Famiano, Richard N. Boyd, Toshitaka Kajino +4
Measurements of the isotopic abundances in meteoritic amino acids have found enhancements of H/H, N/N, and C/C in the amino acids in the meteorites…
