Fingerprint of the first stars: multi-enriched extremely metal-poor stars in the TOPoS survey
Tilman Hartwig, Miho N. Ishigaki, Ralf S. Klessen +1
Extremely metal poor (EMP) stars in the Milky Way inherited the chemical composition of the gas out of which they formed. They therefore carry the chemical fingerprint of the first…
Line identification and photometric history of the hot post-AGB star Hen 3-1013 (IRAS 14331-6435)
V. P. Arkhipova, M. Parthasarathy, N. P. Ikonnikova +4
We present a study of the high-resolution optical spectrum for the hot post-asymptotic giant branch (post-AGB) star, Hen 3-1013, identified as the optical counterpart of the infrar…
Tracing the origin of moving groups I. The γ Leo moving group with high resolution spectra from the Subaru Telescope
Xilong Liang, Jingkun Zhao, Gang Zhao +7
We present chemical abundances of 15 stars in the γ Leo moving group based on high-resolution spectra with the Subaru High Dispersion Spectrograph. The sample was picked up by appl…
LAMOST J2217+2104: a new member of carbon-enhanced extremely metal-poor stars with excesses of Mg and Si
Wako Aoki, Tadafumi Matsuno, Satoshi Honda +4
We report on the elemental abundances of the carbon-enhanced metal-poor (CEMP) star J2217+2104 discovered by our metal-poor star survey with LAMOST and Subaru. This object is a red…
Constraints on the Chemical Enrichment History of the Perseus Cluster of Galaxies from High-Resolution X-ray Spectroscopy
A. Simionescu, S. Nakashima, H. Yamaguchi +32
High-resolution spectroscopy of the core of the Perseus Cluster of galaxies, using the satellite above 2 keV and the - Reflection Grating Spectrometer at lowe…
Optical high-resolution spectroscopy of 14 young -rich stars
Tadafumi Matsuno, David Yong, Wako Aoki +1
We report chemical abundances of 14 young -rich stars including neutron-capture elements based on high-quality optical spectra from HIRES/Keck I and differential line-by-line an…
