Enrichment in r-process elements from multiple distinct events in the early Draco dwarf spheroidal galaxy

Takuji Tsujimoto, Tadafumi Matsuno, Wako Aoki +2

The stellar record of elemental abundances in satellite galaxies is important to identify the origin of r-process because such a small stellar system could have hosted a single r-p…

A hybrid type Ia supernova with an early flash triggered by helium-shell detonation

Ji-an Jiang, Mamoru Doi, Keiichi Maeda +22

Type Ia supernovae (SNe Ia) arise from the thermonuclear explosion of carbon-oxygen white dwarfs. Though the uniformity of their light curves makes them powerful cosmological dista…

R-process Element Cosmic Rays from Neutron Star Mergers

Yutaka Komiya, Toshikazu Shigeyama

Neutron star mergers (NSMs) are one of the most plausible sources of r-process elements in the universe. Therefore NSMs can also be a major source of ultra-heavy elements in cosmic…
