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…
Observational Characteristics and Possible Asphericity of Over-Luminous Type Ia Supernovae
Keiichi Maeda, Koichi Iwamoto
A few Type Ia supernovae (SNe Ia) have been suggested to be an explosion of a super-Chandrasekhar-mass white dwarf (WD) to account for their large luminosities, requiring a large a…
Black hole-black string phase transitions from hydrodynamics
Kei-ichi Maeda, Umpei Miyamoto
We discuss the phase transitions between three states of a plasma fluid (plasma ball, uniform plasma tube, and non-uniform plasma tube), which are dual to the corresponding finite…
Can higher curvature corrections cure the singularity problem in f(R) gravity?
Tsutomu Kobayashi, Kei-ichi Maeda
Although modified gravity models can be made to satisfy solar system and cosmological constraints, it has been shown that they have the serious drawback of the nonexistence…
Supernova Nucleosynthesis and Extremely Metal-Poor Stars
Nozomu Tominaga, Hideyuki Umeda, Keiichi Maeda +2
We investigate hydrodynamical and nucleosynthetic properties of the jet-induced explosion of a population III star and compare the abundance patterns of the yields with…
Evolution of newly formed dust in Population III supernova remnants and its impact on the elemental composition of Population II.5 stars
Takaya Nozawa, Takashi Kozasa, Asao Habe +5
We investigate the evolution of dust formed in Population III supernovae (SNe) by considering its transport and processing by sputtering within the SN remnants (SNRs). We find that…
