Neutrinos from Carbon-Burning Red Supergiants and Their Detectability
Gwangeon Seong, Kyujin Kwak, Dongsu Ryu +1
Stars emit MeV neutrinos during their evolution via nuclear syntheses and thermal processes, and detecting them could provide insights into stellar structure beyond what is accessi…

12C+12C Reaction Rates and the Evolution of a Massive Star
Gwangeon Seong, Yubin Kim, Kyujin Kwak +4
Carbon fusion is important to understand the late stages in the evolution of a massive star. Astronomically interesting energy ranges for the 12C+12C reactions have been, however,…

Effects of pair freeze-out on photon distributions in BBN epoch
Jeongyoon Choi, Dukjae Jang, Youngshin Kwon +5
We investigate the evolution of non-extensivity in the photon distribution during the Big Bang Nucleosynthesis (BBN) epoch using Tsallis statistics. Assuming a minimal deviation fr…
