Does the structure of Pop III supernova ejecta affect the elemental abundance of extremely metal-poor stars?
Gen Chiaki, Nozomu Tominaga
The first generation of metal-free (Pop III) stars are crucial for the production of heavy elements in the earliest phase of structure formation. Their mass scale can be derived fr…
Seeding the second star -- II. CEMP star formation enriched from faint supernovae
Gen Chiaki, John H. Wise, Stefania Marassi +3
Carbon-enhanced metal-poor (CEMP) stars are the living fossils holding records of chemical enrichment from early generations of stars. In this work, we perform a set of numerical s…
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…
Classification of extremely metal-poor stars: absent region in A(C)-[Fe/H] plane and the role of dust cooling
Gen Chiaki, Nozomu Tominaga, Takaya Nozawa
Extremely metal-poor (EMP) stars are the living fossils with records of chemical enrichment history at the early epoch of galaxy formation. By the recent large observation campaign…
Blocking metal accretion onto population III stars by stellar wind
Shuta J. Tanaka, Gen Chiaki, Nozomu Tominaga +1
Low-mass population III (PopIII) stars of could survive up until the present. Non-detection of low-mass PopIII stars in our Galaxy has already put a string…
