The Role of Dust in the Early Universe I : Protogalaxy Evolution [PDF]
, 2011 We develop one-zone galaxy formation models in the early Universe, taking into account dust formation and evolution by supernova (SN) explosions. Especially we focus on the time evolution of dust size distribution, because ${\rm H}_{2}$ formation on the ...

Supernovae within Pre-existing Wind-blown Bubbles: Dust Injection versus Ambient Dust Destruction [PDF]
The Astrophysical Journal, 2019 Abstract By means of 3D hydrodynamical simulations, we evaluate here the impact that supernova (SN) explosions occurring within wind-driven bubbles have on the survival or destruction of dust grains. We consider both the dust generated within the ejecta and the dust initially present in the ambient gas and later locked up in the ...

Rotational Disruption of Astrophysical Dust and Ice—Theory and Applications
Galaxies, 2020 Dust is an essential component of the interstellar medium (ISM) and plays an important role in many different astrophysical processes and phenomena.

Strong Near-Infrared Emission Interior to the Dust-Sublimation Radius of Young Stellar Objects MWC275 and AB Aur [PDF]
, 2008 Using the longest optical-interferometeric baselines currently available, we have detected strong near-infrared (NIR) emission from inside the dust-destruction radius of Herbig Ae stars MWC275 and AB Aur.

Dust Destruction by Drift-induced Sputtering in Active Galactic Nuclei [PDF]
The Astrophysical Journal, 2020 Abstract Recent mid-infrared high spatial resolution observations have revealed that active galactic nuclei (AGNs) may host a polar dust region with the size of several pc, and such dust may be carried by radiation from the central engine. The polar dust emission often exhibits very weak or absence of the silicate 10 μm emission feature.

Dust Destruction in the Interstellar Medium [PDF]
Symposium - International Astronomical Union, 1989 Grains are injected into the interstellar medium (ISM) from evolved stars and supernovae; in addition, supernova ejecta may condense onto pre-existing grains before becoming well-mixed with the interstellar gas. Once in the ISM, grains can grow by accretion, but are also subject to destruction by interstellar shocks. The current status of the theory of

Dust Destruction in the Cygnus Loop Supernova Remnant [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractThe Cygnus Loop supernova remnant serves as an excellent laboratory for the study of radiative and non-radiative shocks with speeds in the 150–450 km s−1 range. We present results on shock-excited emission and dust destruction based on Spitzer Space Telescope observations of two well-studied regions in the remnant, (i) a non-radiative shock ...
