Dust in Supernovae; Formation and Evolution
Takashi Kozasa, Takaya Nozawa, Nozomu Tominaga +3
Core--collapsed supernovae (CCSNe) have been considered to be one of sources of dust in the universe. What kind and how much mass of dust are formed in the ejecta and are injected…
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…
Extinction curves flattened by reverse shocks in supernovae
Hiroyuki Hirashita, Takaya Nozawa, Tsutomu T. Takeuchi +1
We investigate the extinction curves of young galaxies in which dust is supplied from Type II supernovae (SNe II) and/or pair instability supernovae (PISNe). Since at high redshift…
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…
