Comprehensive Analyses of the Neutrino-Process in the Core-collapsing Supernova
Heamin Ko, Dukjae Jang, Myung-Ki Cheoun +8
We investigate the neutrino flavor change effects due to neutrino self-interaction, shock wave propagation as well as matter effect on the neutrino-process of the core-collapsing s…
Thermonuclear 17O(n,gamma)18O reaction rate and its astrophysical implications
Li-Yong Zhang, Jian-Jun He, Motohiko Kusakabe +2
A new thermonuclear O(,)O rate is derived based on a complete calculation of the direct-capture (DC) and resonant-capture contributions, for a temperature regio…
A Relativistic Quantum Approach to Neutrino and Antineutrino Emissions via the Direct Urca Process in Strongly Magnetized Neutron-Star Matter
Tomoyuki Maruyama, A. Baha Balantekind, Myung-Ki Cheoung +3
We study neutrino and antineutrino emission from the direct Urca process in neutron-star matter in the presence of strong magnetic fields. We calculate the neutrino emissivity of t…
Dynamical Screening Effects on Big Bang Nucleosynthesis
Eunseok Hwang, Dukjae Jang, Kiwan Park +6
A moving ion in plasma creates a deformed electric potential depending on the ion velocity, which leads to the distinct screening effect compared to the standard static Salpeter fo…
Analysis of the Multi-component Relativistic Boltzmann Equation for Electron Scattering in Big Bang Nucleosynthesis
Nishanth Sasankan, Atul Kedia, Motohiko Kusakabe +1
Big-bang nucleosynthesis (BBN) is valuable as a means to constrain the physics of the early universe and it is the only probe of the radiation-dominated epoch. A fundamental assump…
Effects of sterile neutrino and extra-dimension on big bang nucleosynthesis
Dukjae Jang, Motohiko Kusakabe, Myung-Ki Cheoun
By assuming the existence of extra-dimensional sterile neutrinos in big bang nucleosynthesis (BBN) epoch, we investigate the sterile neutrino () effects on the BBN and c…
