Exploring highly-deformed ground states involving the second intruder orbit in Z>50 even-even nuclei
Tsunenori Inakura, Wataru Horiuchi, Shin'ichiro Michimasa +1
We present a systematic survey of even-even nuclei with to identify where a very large prolate configuration driven by the second intruder orbit emerges. Within the energy d…
The -Process Alliance: Enrichment of -process Elements in a Simulated Milky Way-like Galaxy
Yutaka Hirai, Timothy C. Beers, Young Sun Lee +11
We study the formation of stars with varying amounts of heavy elements synthesized by the rapid neutron-capture process (-process) based on our detailed cosmological zoom-in sim…
Theoretical study of Th III energy levels and transitions for applications to kilonova spectra
Laima KitovienÄ, Gediminas Gaigalas, Pavel Rynkun +3
The neutron star merger is a promising site of heavy element production. By producing heavy elements, the neutron star merger gives rise to a thermal transient called a kilonova. S…
Systematic opacity calculations for kilonovae -- II. Improved atomic data for singly ionized lanthanides
Daiji Kato, Masaomi Tanaka, Gediminas Gaigalas +2
Lanthanides play most important roles in the opacities for kilonova, ultraviolet-optical-infrared emission from neutron star mergers. Although several efforts have been made to con…
Revisiting Near-Infrared Features of Kilonovae: The Importance of Gadolinium
Salma Rahmouni, Masaomi Tanaka, Nanae Domoto +7
The observation of the kilonova AT2017gfo and investigations of its light curves and spectra confirmed that neutron star mergers are sites of r-process nucleosynthesis. However, th…
Thorium in Kilonova Spectra: Exploring the Heaviest Detectable Element
Nanae Domoto, Shinya Wanajo, Masaomi Tanaka +2
Kilonova spectra provide us with the direct information of r-process nucleosynthesis in neutron star mergers. In this paper, we study the signatures of elements beyond the third r-…
