Hypernovae and their Nucleosynthesis
Ken'ichi Nomoto, Keiichi Maeda, Hideyuki Umeda +3
We review the characteristics of nucleosynthesis in 'Hypernovae', i.e., core-collapse supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs). The hypernova yields s…
Carbon Monoxide in the Type Ic SN 2000ew
Christopher L. Gerardy, Robert A. Fesen, Ken'ichi Nomoto +3
We present K-band (1.9 -- 2.5 micron) spectra of the Type Ic SN 2000ew observed with IRCS on the Subaru Telescope. These data show the first detection of carbon monoxide (CO) emiss…
Perturbation theory in Lagrangian hydrodynamics for a cosmological fluid with velocity dispersion
Takayuki Tatekawa, Momoko Suda, Kei-ichi Maeda +2
We extensively develop a perturbation theory for nonlinear cosmological dynamics, based on the Lagrangian description of hydrodynamics. We solve hydrodynamic equations for a self-g…
