Near-infrared spectra of chemically peculiar stars and applications to kilonova spectra
Nanae Domoto, Masaomi Tanaka, Wako Aoki +11
Kilonova spectra provide information on rapid neutron-capture nucleosynthesis in neutron star mergers. However, it remains challenging to identify individual elements in kilonova s…
Heavy element dust explains the late-time spectra of kilonovae
Nanae Domoto, Kenta Hotokezaka, Daniel Kasen
Neutron star mergers are a leading site of -process, producing radioactively powered optical and infrared transients known as kilonovae. Observations of the kilonovae AT2017gfo,…
Theoretical study of Th III energy levels and transitions for applications to kilonova spectra
Laima Kitovienė, 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…
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-…
Theoretical investigation of energy levels and transitions for Ce III with applications to kilonova spectra
G. Gaigalas, P. Rynkun, N. Domoto +3
Doubly ionized cerium (Ce) is one of the most important ions to understand the kilonova spectra. In particular, near-infrared (NIR) transitions of Ce III between the ground…
Three dimensional end-to-end simulation for kilonova emission from a black-hole neutron-star merger
Kyohei Kawaguchi, Nanae Domoto, Sho Fujibayashi +5
We study long-term evolution of the matter ejected in a black-hole neutron-star (BH-NS) merger employing the results of a long-term numerical-relativity simulation and nucleosynthe…
Transition probabilities of near-infrared Ce III lines from stellar spectra: applications to kilonovae
Nanae Domoto, Jae-Joon Lee, Masaomi Tanaka +6
Kilonova spectra provide us with information of r-process nucleosynthesis in neutron star mergers. However, it is still challenging to identify individual elements in the spectra m…
Heavy element nucleosynthesis associated with a gamma-ray burst
James H. Gillanders, Eleonora Troja, Chris L. Fryer +9
Kilonovae are a novel class of astrophysical transients, and the only observationally-confirmed site of rapid neutron capture nucleosynthesis (the r-process) in the Universe. To da…
Kilonovae of binary neutron star mergers leading to short-lived remnant neutron star formation
Kyohei Kawaguchi, Sho Fujibayashi, Nanae Domoto +3
We study kilonova emission from binary neutron star (BNS) mergers for the case that a remnant massive neutron star (MNS) forms and collapses to a black hole within ms after th…
Cerium features in kilonova near-infrared spectra: implication from a chemically peculiar star
Masaomi Tanaka, Nanae Domoto, Wako Aoki +14
Observations of the kilonova from a neutron star merger event GW170817 opened a way to directly study r-process nucleosynthesis by neutron star mergers. It is, however, challenging…
Non-LTE analysis for Helium and Strontium lines in the kilonova AT2017gfo
Yuta Tarumi, Kenta Hotokezaka, Nanae Domoto +1
Kilonova spectra imprint valuable information about the elements synthesized in neutron star mergers. In AT2017gfo, the kilonova associated with GW170817, the spectroscopic feature…
Lanthanide Features in Near-infrared Spectra of Kilonovae
Nanae Domoto, Masaomi Tanaka, Daiji Kato +3
The observations of GW170817/AT2017gfo have provided us with evidence that binary neutron star mergers are sites of -process nucleosynthesis. However, the observed signatures in…
Opacity of the highly ionized lanthanides and the effect on the early kilonova
Smaranika Banerjee, Masaomi Tanaka, Daiji Kato +3
We investigate the effect of the presence of lanthanides (Z = 57- 71) on the kilonova at t~hours after the neutron star merger for the first time. For this purpose, we calculate th…
Signatures of r-process elements in kilonova spectra
Nanae Domoto, Masaomi Tanaka, Shinya Wanajo +1
Binary neutron star (NS) mergers have been expected to synthesize r-process elements and emit radioactively powered radiation, called kilonova. Although r-process nucleosynthesis w…
