Dust Destruction in Shock Waves in the Cygnus Loop
The Astrophysical JournalSupernova remnant (SNR) shock waves are known to be important sources of dust destruction in the interstellar medium. Models of dust destruction in shocks have made various predictions of the destruction efficiency, but have generally been difficult to ...

DESTRUCTION OF INTERSTELLAR DUST IN EVOLVING SUPERNOVA REMNANT SHOCK WAVES [PDF]
Astrophysical Journal, 2015 Supernova generated shock waves are responsible for most of the destruction of dust grains in the interstellar medium (ISM). Calculations of the dust destruction timescale have so far been carried out using plane parallel steady shocks, however that approximation breaks down when the destruction timescale becomes longer than that for the evolution of ...

Chondrule Destruction via Dust Collisions in Shock Waves
The Astrophysical JournalA leading candidate for the heating source of chondrules and igneous rims is shock waves. This mechanism generates high relative velocities between chondrules and dust particles.

JOYS: Launch and destruction of dust in protostellar jets
Astronomy & AstrophysicsContext. Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique to mid-infrared (IR) wavelengths reveal refractories eroded from ...

Cosmic dust evolution: The challenges for NIKA2 [PDF]
EPJ Web of Conferences, 2022 I summarize a recent study aimed at constraining dust evolution timescales in nearby galaxies. We were able to quantify the effciency of dust condensation in SN II ejecta, grain growth in the ISM and dust destruction by SN II blast waves.

Universe, 2022 The presence of dust in the intracluster medium (ICM) has been a long-standing problem that is still awaiting elucidation. Direct observational diagnostics are rather challenging (though not impossible) either because of a sparse distribution of dust in ...

Dust Destruction in Nonradiative Shocks [PDF]
The Astrophysical Journal, 2019 Abstract Supernova remnant (SNR) shock waves are the main place where interstellar dust grains are destroyed. However, the dust destruction efficiency in nonradiative shocks is still not well known. One way to estimate the fraction of dust destroyed is to compare the difference between postshock gas abundances and preshock medium total ...

Galaxy simulation with dust formation and destruction [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We perform smoothed particle hydrodynamics (SPH) simulations of an isolated galaxy with a new treatment for dust formation and destruction. To this aim, we treat dust and metal production self-consistently with star formation and supernova feedback. For dust, we consider a simplified model of grain size distribution by representing the entire range of ...
