Interstellar shock waves can erode and destroy grains present in the shocked gas, primarily as the result of sputtering and grain-grain collisions. Uncertainties in current estimates of sputtering yields are reviewed. Results are presented for the simple case of sputtering of fast grains being stopped in cold gas. An upper limit is derived for sputtering of refractory grains in C-type MHD shocks: shock speedsvs≳ 50 km s−1 are required for return of more than 30% of the silicate to the gas phase… Expand

The Physical and Chemical Effects of C-Shocks in Molecular Outflows
The bow shocks which are observed in jets associated with low-mass star formation probably have C-shock characteristics over at least part of their extent. We show that ion-neutral streaming inExpand
Destruction of Interstellar Dust
Interstellar dust is an important component of the interstellar medium. Dust grains are the dominant opacity source and thus regulate the radiative transfer in the interstellar medium. Besides theExpand
Parametrization of C-shocks. Evolution of the sputtering of grains
Context. The detection of narrow SiO line emission toward the young shocks of the L1448-mm outflow has been interpreted as a signature of the magnetic precursor of C-shocks. In contrast with the lowExpand
Monte Carlo Calculations of the Sputtering of Grains: Enhanced Sputtering of Small Grains
The sputtering of a small grain embedded in a plasma or hot gas in the interstellar medium (ISM) is calculated using a Monte Carlo binary collision code. This technique is used to describe theExpand
Evaporation of grain-surface species by shock waves in proto-planetary disk
Recent ALMA (Atacama Large Millimeter/submillimeter Array) observations of young protostellar objects detected warm SO emission, which could be associated with a forming protostellar disk. In orderExpand
Chemical evolution of the gas in C-type shocks in dark clouds
A magnetohydrodynamic model of a steady, transverse C-type shock in a dense molecular cloud is presented. A complete gas–grain chemical network is taken into account: the gas-phase chemistry, theExpand
Intergalactic medium metal enrichment through dust sputtering
We study the motion of dust grains into the intergalactic medium (IGM) around redshift z = 3, to test the hypothesis that grains can efficiently pollute the gas with metals through sputtering. We useExpand
INTERSTELLAR H2O MASERS FROM J SHOCKS
We present a model in which the 22 GHz H2O masers observed in star-forming regions occur behind shocks propagating in dense regions (preshock density n 0 ~ 106-108 cm–3). We focus on high-velocityExpand
Bow shocks, bow waves, and dust waves – II. Beyond the rip point
Dust waves are a result of gas-grain decoupling in a stream of dusty plasma that flows past a luminous star. The radiation field is sufficiently strong to overcome the collisional coupling betweenExpand
Ion Interactions with Solids: Astrophysical Applications
Energetic plasma ions and electrons can significantly alter surfaces in the solar system and the interstellar medium (ISM) and produce observable gas-phase atoms and molecules. In order to understandExpand
