Dust around Type Ia supernovae
An explanation is given of the low value of Rλ ≡ Aλ/E(B − V ), the ratio of absolute to selective extinction deduced from Type Ia supernova observations. The idea involves scattering by dust clouds located in the circumstellar environment, or at the highest velocity shells of the supernova ejecta. The scattered light tends to reduce the effective Rλ in the optical, but has an opposite effect in...
متن کاملDust Formation in Very Massive Primordial Supernovae
At redshift z ∼ > 5 Type II supernovae (SNII) are the only known dust sources with evolutionary timescales shorter than the Hubble time. We extend the model of dust formation in the ejecta of SNII by Todini & Ferrara (2001) to investigate the same process in pair-instability supernovae (SNγγ), which are though to arise from the explosion of the first, metal free, very massive (140-260 M⊙) stars...
متن کاملDust in Supernovae; Formation and Evolution
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 into the interstellar medium (ISM) depend on the type of CCSNe, through the difference in the thickness (mass) of outer envelope. In this review, after summarizing the existing results of observations on dust formation...
متن کاملDust in the Host Galaxies of Supernovae
We present Spitzer/MIPS 24μm observations of 50 supernova host galaxies at 0.1 < z < 1.7 in the Great Observatories Origins Deep Survey (GOODS) fields. We also discuss the detection of SN host galaxies in SCUBA/850μm observations of GOODS-N and Spitzer/Infrared Spectrograph (IRS) 16μm observations of GOODS-S. About 60% of the host galaxies of both Type Ia and core-collapse supernovae are detect...
