Origin and Nature of Dust in the Early Universe
T. Nozawa, T. Kozasa, H. Umeda +8
We present recent advances in theoretical studies of the formation and evolution of dust in primordial supernovae (SNe) that are considered to be the main sources of dust in the ea…
Properties of newly formed dust by SN2006jc based on near-to-mid infrared observation with AKARI
I. Sakon, T. Wada, Y. Ohyama +18
We present our latest results on near- to mid- infrared observation of SN2006jc at 200 days after the discovery using the Infrared Camera (IRC) on board . The near-infrared…
The Connection between Gamma-Ray Bursts and Extremely Metal-Poor Stars: Black Hole-forming Supernovae with Relativistic Jets
Nozomu Tominaga, Keiichi Maeda, Hideyuki Umeda +5
Long-duration gamma-ray bursts (GRBs) are thought to be connected to luminous and energetic supernovae (SNe), called hypernovae (HNe), resulting from the black-hole (BH) forming co…
Galactic chemical evolution: Carbon through Zinc
C. Kobayashi, H. Umeda, K. Nomoto +2
We calculate the evolution of heavy element abundances from C to Zn in the solar neighborhood adopting our new nucleosynthesis yields. Our yields are calculated for wide ranges of…
