Research Highlights in 2018

Cosmochronometer 98Tc is produced abundantly by supernova electron antineutrinos
An international collaboration including Toshitaka Kajino and Motohiko Kusakabe (2018 NAOJ Visiting Professor) in the COSNAP group found that the short-lived nuclide 98Tc is produced significantly by reactions of electron antineutrinos with nuclei in supernovae. In the end of massive stellar evolution, supernovae occur and an extremely large number of neutrinos and antineutrinos are emitted from a neutron star in the center. The collaboration group calculated nucleosynthesis of 98Tc in supernovae taking into account neutrino and antineutrino reactions of preexisting nuclei. It was then shown that the charged-current anti-neutrino reactions significantly contribute to the production of 98Tc in supernovae. The 98Tc is the first nuclide whose production was found to be sensitive to the antineutrino energy spectrum. It is a potential chronometer for the time between the last supernova before the solar system formation and the meteoritic formation. Therefore, future measurements of its meteoritic abundance can be used to deduce the antineutrino spectrum and the time scale of the meteoritic formation. (September, 2018)

Nucleosynthesis Constraints on the Explosion Mechanism for Type Ia Supernovae
Type Ia supernovae (SNe Ia) play important roles in cosmology as a standard candle, although their progenitors and explosion mechanisms have been a long-standing mystery. One possible solution is to compare theoretical and observational nucleosynthetic yields, which needs careful collaboration among theories, observations, and experiments of astronomy and nuclear physics. Recent observations have revealed the abundances of radioactive elements including manganese, cobalt, iron, and nickel. We perform collaboration among researchers on supernova theories, astronomical observations, and experimental nuclear physics to calculate these abundances precisely. Comparison between the observed and the calculated isotopic ratios shows the way to diagnose explosion mechanisms of SNe Ia. In addition to that, it is pointed out that yields of some neutron-rich nuclei are good indicators of the density, therefore can constrain progenitors and explosion mechanisms if they are observed.  (September, 2018)

Why are we all left handed? - Theory of elementary particle origin
International collaboration team among scientists at NAOJ, The University of Tokyo, Western Michigan University and Ohio State University has come up with a possible way in which Mother Nature selects left-handed amino acids in space. This new theory brings together fundamental particle physics, electromagnetism, biology, and chemistry. Molecules in magnetic fields can interact with leptons (some of the tiniest particles in nature which include electrons and neutrinos). Neutrino chirality is completely broken. Because leptons can also be chiral, they interact with amino acids differently depending on the combination of lepton chirality and amino acid chirality. This interaction can selectively destroy one mirror image more than the other, resulting in the imbalance that we see in meteorites. Since Louis Pasteur studied molecular chirality nearly 170 years ago, a question how amino acids got to be left-handed is one of the biggest questions in science. Not only does this discovery predict how amino acids got to be left-handed, it also predicts how they became left-handed in space. The ramifications for life on the earth and elsewhere in the cosmos are significant. The latest news on this discovery was published in Scientific Reports (a Nature journal) on Monday, June 11 at 10am GMT.  (June, 2018)
