Impact of dineutrons on nuclear compositions of a core-collapse supernova

Tatsuya Matsuki, Shun Furusawa, Katsuhiko Suzuki

We study the nuclear compositions in the central region of a core-collapse supernova, assuming the existence of dineutrons (${}^{2}n$) and tetraneutrons (${}^{4}n$). At 100~ms after core b…
