Atomic data benchmarked by Large-scale Multiconfiguration Dirac-Hartree-Fock Calculations for Beryllium
Sijie Wu, Shaowei Tian, Ran Si +6
The multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) methods are used to provide excitation energies, radiative transition data, lifet…
The MARTINI Platform (I): Se I-X atomic calculation and expansion opacity for early-stage kilonova spectral analysis
Matteo Bezmalinovich, Mattia Bulla, Gediminas Gaigalas +3
Kilonovae represent key sites of r-process nucleosynthesis, making opacity estimation and spectral analysis crucial for constraining their composition. Since light r-process elemen…
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…
