Unique chemical composition of the very metal-poor star LAMOST J1645+4357
Wako Aoki, Haining Li, Nozomu Tominaga +3
We report on the chemical composition of the very metal-poor ([Fe/H]=-2.9) star LAMOST J1645+4357 that is identified to be a red giant having peculiar abundance ratios by Li et al.…
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…
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…
Gaia DR2 and EDR3 data and evolutionary status of post-AGB stars with high radial velocities
Wako Aoki, Tadafumi Matsuno, Mudumba Parthasarathy
Using the Gaia DR2 and EDR3 data and list of post-AGB candidates, we investigate the parallax, proper motion and binarity for twenty post-AGB stars and candidates having high radia…
Origin of highly -process-enhanced stars in a cosmological zoom-in simulation of a Milky Way-like galaxy
Yutaka Hirai, Timothy C. Beers, Masashi Chiba +5
The -process-enhanced (RPE) stars provide fossil records of the assembly history of the Milky Way and the nucleosynthesis of the heaviest elements. Observations by the -Proce…
A Super-Earth Orbiting Near the Inner Edge of the Habitable Zone around the M4.5-dwarf Ross 508
Hiroki Harakawa, Takuya Takarada, Yui Kasagi +46
We report the near-infrared radial-velocity (RV) discovery of a super-Earth planet on a 10.77-day orbit around the M4.5 dwarf Ross 508 (). Using precision RVs f…
