Efficiency of the top-down PAH-to-fullerene conversion in UV irradiated environments
M. S. Murga, V . V. Akimkin, D. S. Wiebe
Polycyclic aromatic hydrocarbons (PAHs) and fullerenes play a major role in the physics and chemistry of the interstellar medium. Based on a number of recent experimental and theor…
Dust grains cannot grow to millimeter sizes in protostellar envelopes
Kedron Silsbee, Vitaly Akimkin, Alexei V. Ivlev +3
A big question in the field of star and planet formation is the time at which substantial dust grain growth occurs. The observed properties of dust emission across different wavele…
Shiva: the dust destruction model
M. S. Murga, D. S. Wiebe, E. E. Sivkova +1
We 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…
Infrared Photometric Properties of Inner and Outer Parts of HII regions
A. P. Topchieva, V. V. Akimkin, G. V. Smirnov-Pinchukov
The fact that infrared ring nebulae (IRRNs) are frequently associated with HII regions, provides us the opportunity to study dust at the interface between ionized and neutral gas.…
Dust dynamics and evolution in HII regions - II. Effects of dynamical coupling between dust and gas
V. V. Akimkin, M. S. Kirsanova, Ya. N. Pavlyuchenkov +1
In this paper, we extend the study initiated in PaperI by modelling grain ensemble evolution in a dynamical model of an expanding HII region and checking the effects of momentum tr…
Stochastic grain heating and mid-infrared emission in protostellar cores
Ya. N. Pavlyuchenkov, D. S. Wiebe, V. V. Akimkin +2
Stochastic heating of small grains is often mentioned as a primary cause of large infrared (IR) fluxes from star-forming galaxies, e.g. at 24μm. If the mechanism does work at a gal…
