SN 2005ip: A Luminous Type IIn Supernova Emerging from a Dense Circumstellar Medium as Revealed by X-Ray Observations
Satoru Katsuda, Keiichi Maeda, Takaya Nozawa +2
We report on X-ray spectral evolution of the nearby Type IIn supernova (SN) 2005ip, based on Chandra and Swift observations covering from ~1 to 6 years after the explosion. X-ray s…
Formulation of Non-steady-state Dust Formation Process in Astrophysical Environments
Takaya Nozawa, Takashi Kozasa
The non-steady-state formation of small clusters and the growth of grains accompanied by chemical reactions are formulated under the consideration that the collision of key gas spe…
Properties of Newly Formed Dust Grains in The Luminous Type IIn Supernova 2010jl
K. Maeda, T. Nozawa, D. K. Sahu +15
Supernovae (SNe) have been proposed to be the main production sites of dust grains in the Universe. Our knowledge on their importance to dust production is, however, limited by obs…
What determines the grain size distribution in galaxies?
Ryosuke S. Asano, Tsutomu T. Takeuchi, Hiroyuki Hirashita +1
We construct a dust evolution model taking into account the grain size distribution, and investigate what kind of dust processes determine the grain size distribution at each stage…
SN 2009js at the crossroads between normal and subluminous Type IIP supernovae: optical and mid-infrared evolution
P. Gandhi, M. Yamanaka, M. Tanaka +8
We present a study of SN 2009js in NGC 918. Multi-band Kanata optical photometry covering the first ~120 days show the source to be a Type IIP SN. Reddening is dominated by that du…
Growth of dust grains in a low-metallicity gas and its effect on the cloud fragmentation
Gen Chiaki, Takaya Nozawa, Naoki Yoshida
In a low-metallicity gas, rapid cooling by dust thermal emission is considered to induce cloud fragmentation and play a vital role in the formation of low-mass stars (<~ 1 M_sun) i…
