Cerium Features in Kilonova Near-infrared Spectra: Implication from a Chemically Peculiar Star

Masaomi Tanaka et al.

Summary: Studying the spectra of chemically peculiar stars can provide valuable insights into the spectra of kilonovae, which are produced by neutron star mergers. By comparing the near-infrared spectrum of the chemically peculiar star HR 465 with the spectra of kilonovae, researchers have found that they share similar lanthanide abundances and ionization degrees. This supports the recent identification of the absorption feature observed in GW170817 as Ce iii.

Multiepoch Optical Spectroscopy of the Post-AGB Star HD 161796

Karlis Pukitis et al.

Summary: The study of the pulsating post-AGB star HD 161796 over 18 years reveals phenomena such as shock waves, mass loss, and temperature changes. It confirms that the stellar surface is hotter when the star is smaller in size, indicating a higher evolutionary rate.

Modelling the spectra of the kilonova AT2017gfo-I. The photospheric epochs

J. H. Gillanders et al.

Summary: GW170817 is the only known electromagnetic counterpart to a gravitational wave source. By comparing experimental data and radiative transfer models, we find that the blue spectrum at +1.4 d after merger requires a nucleosynthetic trajectory with high electron fraction, while subsequent spectra require the presence of lanthanide material. The results support the "two-component" kilonova model and constrain the element composition from nucleosynthetic trajectories.

Lanthanide Features in Near-infrared Spectra of Kilonovae

Nanae Domoto et al.

Summary: The observations of GW170817/AT2017gfo suggest that binary neutron star mergers are sites of r-process nucleosynthesis. This paper investigates the kilonova spectra over the entire wavelength range and identifies the elements that produce prominent absorption lines. La III and Ce III are found to appear in the near-infrared spectra, explaining the absorption features observed in GW170817/AT2017gfo spectra.

Multiconfiguration Dirac-Hartree-Fock radiative parameters for emission lines in Ce II-IV ions and cerium opacity calculations for kilonovae

H. Carvajal Gallego et al.

Summary: Large-scale calculations were conducted on singly, doubly, and trebly ionized cerium, using the purely relativistic MCDHF method to account for electronic correlations. The obtained results were used to calculate expansion opacities observed in kilonovae from neutron star mergers, surpassing previous studies in completeness of atomic data and monochromatic opacities for Ce II, Ce III, and Ce IV ions.

Signatures of r-process Elements in Kilonova Spectra

Nanae Domoto et al.

Summary: Binary neutron star mergers are expected to synthesize r-process elements and emit radiation called kilonovae. Line strength calculations and radiative transfer simulations in NS merger ejecta help identify elements in kilonova spectra, showing strong Sr ii and Ca ii lines in lanthanide-poor models, while lanthanide-rich models exhibit features of doubly ionized heavy elements like Ce, Tb, and Th. The absence of Ca ii lines in GW170817/AT2017gfo suggests a low Ca/Sr ratio consistent with certain nucleosynthesis conditions.
