Seeding the Second Star: enrichment from population III, dust evolution, and cloud collapse
Gen Chiaki, John H. Wise
We investigate the formation of extremely metal-poor (EMP) stars that are observed in the Galactic halo and neighboring ultra-faint dwarf galaxies. Their low metal abundances (${\r…
Low-luminosity Type IIP Supernova 2016bkv with early-phase circumstellar interaction
Tatsuya Nakaoka, Koji S. Kawabata, Keiichi Maeda +22
We present optical and near-infrared observations of a low-luminosity Type IIP supernova (SN) 2016bkv from the initial rising phase to the plateau phase. Our observations show that…
Obscured Star Formation in the Host Galaxies of Superluminous Supernovae
B. Hatsukade, N. Tominaga, M. Hayashi +7
We present the results of 3 GHz radio continuum observations of the 8 host galaxies of super-luminous supernovae (SLSNe) at by using the Karl G. Jansky Very Large A…
Metal-poor star formation triggered by the feedback effects from Pop III stars
Gen Chiaki, Hajime Susa, Shingo Hirano
Metal enrichment by the first-generation (Pop III) stars is the very first step of the matter cycle in the structure formation and it is followed by the formation of extremely meta…
Descendants of the first stars: the distinct chemical signature of second generation stars
Tilman Hartwig, Naoki Yoshida, Mattis Magg +9
Extremely metal-poor (EMP) stars in the Milky Way (MW) allow us to infer the properties of their progenitors by comparing their chemical composition to the metal yields of the firs…
