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 ...

Supernova dust destruction in the magnetized turbulent ISM
Nature Communications, 2023 Abstract Dust in the interstellar medium (ISM) is critical to the absorption and intensity of emission profiles used widely in astronomical observations, and necessary for star and planet formation. Supernova explosions (SNe) eject dust into the ISM, but potentially destroy much larger quantities already present in the ambient ISM.

The Dynamics, Destruction, and Survival of Supernova-formed Dust Grains [PDF]
The Astrophysical Journal, 2020 Abstract Observations have demonstrated that supernovae efficiently produce dust. This is consistent with the hypothesis that supernovae and asymptotic giant branch stars are the primary producers of dust in the universe. However, there has been a longstanding question of how much of the dust detected in the interiors of young supernova ...

Dust destruction at high galactic altitude [PDF]
Астрономия и исследование космического пространства: Всероссийская с международным участием научная конференция студентов и молодых ученых, посвященная памяти Полины Евгеньевны Захаровой, 2021 The possibility of destruction carbonaceous dust particles swept out by the radiation pressure into near-galactic space due to the relative motion of dust particles of various sizes is considered. The earlier model of the motion of dust in the Galaxy under the action of radiation pressure, gravity, and gas resistance is expanded taking into account the

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 at high Galactic altitude
ASTRONOMY AT THE EPOCH OF MULTIMESSENGER STUDIES. Proceedings of the VAK-2021 conference, Aug 23–28, 2021, 2022 We consider the destruction of dust at high galactic altitudes based on an earlier developed model of the movement of dustin the Galaxy, due to the stellar radiation pressure, gravity and gas drag. The possibility of dust sweeping is consideredtaking into account its collisions with the Galactic gas and between dust particles.
