Impact of HAC evolution on the formation of small hydrocarbons in the Orion Bar and the Horsehead PDRs
M. S. Murga, A. I. Vasyunin, M. S. Kirsanova
We study evolution of hydrogenated amorphous carbon (HAC) grains under harsh UV radiation in photo-dissociation regions (PDRs) near young massive stars. Our aim is to evaluate the…
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…
Orion Bar as a window to the evolution of PAHs
Maria S. Murga, Maria S. Kirsanova, Dmitry S. Wiebe +1
We investigate the mid-infrared (IR) emission in the Orion Bar photodissociation region, using archival photometric and spectroscopic observations from UKIRT, Spitzer, ISO, and SOF…
Spectral energy distributions of dust and PAHs based on the evolution of grain size distribution in galaxies
Hiroyuki Hirashita, Weining Deng, Maria S. Murga
Based on a one-zone evolution model of grain size distribution in a galaxy, we calculate the evolution of infrared spectral energy distribution (SED), considering silicate, carbona…
Impact of PAH photodissociation on the formation of small hydrocarbons in the Orion Bar and the Horsehead PDRs
M. S. Murga, M. S. Kirsanova, A. I. Vasyunin +1
We study whether polycyclic aromatic hydrocarbons (PAHs) can be a weighty source of small hydrocarbons in photo-dissociation regions (PDRs). We modeled the evolution of 20 specific…
Self-consistent modelling of aromatic dust species and extinction curves in galaxy evolution
Hiroyuki Hirashita, Maria S. Murga
We formulate and calculate the evolution of dust in a galaxy focusing on the distinction among various dust components -- silicate, aromatic carbon, and non-aromatic carbon. We tre…
