shiva: a dust destruction model [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACTWe present a numerical tool, shiva, designed to simulate the dust destruction in warm neutral, warm ionized and hot ionized media under the influence of photo-processing, sputtering and shattering. The tool is designed primarily to study the evolution of hydrogenated amorphous carbons (HACs), but options to simulate polycyclic aromatic ...

Revisiting the dust destruction efficiency of supernovae [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Dust destruction by supernovae is one of the main processes removing dust from the interstellar medium (ISM). Estimates of the efficiency of this process, both theoretical and observational, typically assume a shock propagating into a homogeneous medium, whereas the ISM possesses significant substructure in reality.

Dust destruction in the ISM: a re-evaluation of dust lifetimes [PDF]
Astronomy & Astrophysics, 2011 There is a long-standing conundrum in interstellar dust studies relating to the discrepancy between the time-scales for dust formation from evolved stars and the apparently more rapid destruction in supernova-generated shock waves. Aims. We re-examine some of the key issues relating to dust evolution and processing in the interstellar medium.

The impact of metallicity-dependent dust destruction on the dust-to-metals ratio in galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 ABSTRACT The ratio of the mass of interstellar dust to the total mass of metals (the dust-to-metals/DTM ratio) tends to increase with metallicity. This can be explained by the increasing efficiency of grain growth in the interstellar medium (ISM) at higher metallicities, with a corollary being that the low DTM ratios seen at low ...

Dust destruction and survival in the Cassiopeia A reverse shock [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Core-collapse supernovae (CCSNe) produce large ($\gtrsim0.1\,{\rm M}_\odot$) masses of dust, and are potentially the primary source of dust in the Universe, but much of this dust may be destroyed before reaching the interstellar medium.

Destruction mechanisms for interstellar dust
The Astrophysical Journal, 1979 Destruction rates are estimated for interstellar dust grains as a function of size and composition of the grains, and the type of region in which the grain is located. Several idealized models of the interstellar medium are considered. The destruction mechanisms examined include sputtering and grain-grain collisions in interstellar shocks, sputtering ...

Monthly Notices of the Royal Astronomical Society, 2012 We present basic theoretical constraints on the effects of destruction by supernovae (SNe) and growth of dust grains in the interstellar medium (ISM) on the radial distribution of dust in late-type galaxies.

The role of dust destruction and dust growth in the evolution of the interstellar medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We use Milky Way-like chemodynamical simulations with a new treatment for dust destruction and growth to investigate how these two processes affect the properties of the interstellar medium in galaxies. We focus on the role of two specific parameters, namely fdes (a new parameter that determines the fraction of dust destroyed in

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.
