Binary neutron star (NS) merger is a promising site for the rapid neutron capture nucleosynthesis (r-process). The radioactive decay of newly synthesized elements powers electromagnetic radiation, as called kilonova. The detection of gravitational wave from a NS merger GW170817 and the observation of the associated kilonova AT2017gfo have provided with us the evidence that r-process happens in...
Stars of 8-10 M⊙ are theoretically considered to become Super Asymptotic Giant Branch (SAGB), and explode as electron capture supernovae (ECSNe). However, there are no observation which is clearly identified as an ECSN. Although SN1054 (Crab Nebula) is considered to be an ECSN, we could hardly know its explosion as detail as modern observation. SN2018zd is a controversial object. Although it...
Neutron star mergers (NSMs) have been confirmed as one of the production sites of the heaviest elements. Studying post-NSM signals in the electromagnetic spectrum is invaluable for understanding the production of these elements, especially with the LIGO Scientific Collaboration having begun its next observing run. However, with the current low detection rates of post-merger light curves, we...
A star more than eight times the mass of the sun undergoes a massive explosion called a supernova at the end of its life. Supernova explosions, including the emission of neutrinos, gravitational waves, and beyond SM particles, are ideal targets for multi-messenger astronomy. One issue in the study of supernova explosions is that research has mainly focused on the first second of the explosion....
