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…
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…
Early Formation of Dust in the Ejecta of Type Ib SN 2006jc and Temperature and Mass of the Dust
T. Nozawa, T. Kozasa, N. Tominaga +8
SN 2006jc is a peculiar supernova (SN), in which the formation of dust has been confirmed at an early epoch of ~50 days after the explosion. We investigate the possibility of such…
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 Peculiar Type Ib Supernova 2006jc: A WCO Wolf-Rayet Star Explosion
N. Tominaga, M. Limongi, T. Suzuki +21
We present a theoretical model for Type Ib supernova (SN) 2006jc. We calculate the evolution of the progenitor star, hydrodynamics and nucleosynthesis of the SN explosion, and the…
Freshly Formed Dust in the Cassiopeia A Supernova Remnant as Revealed by the Spitzer Space Telescope
J. Rho, T. Kozasa, W. T. Reach +6
We performed Spitzer Infrared Spectrograph mapping observations covering nearly the entire extent of the Cassiopeia A supernova remnant (SNR), producing mid-infrared (5.5-35 micron…
