Dehydrogenated polycyclic aromatic hydrocarbons and UV bump
G. Malloci, G. Mulas, C. Cecchi-Pestellini +1
Recent calculations have shown that the UV bump at about 217.5 nm in the extinction curve can be explained by a complex mixture of PAHs in several charge states. Other studies prop…
The role of the charge state of PAHs in ultraviolet extinction
C. Cecchi-Pestellini, G. Malloci, G. Mulas +2
Aims: We explore the relation between charge state of polycyclic aromatic hydrocarbons (PAHs) and extinction curve morphology. Methods: We fit extinction curves with a dust model i…
On-line database of the spectral properties of polycyclic aromatic hydrocarbons
G. Malloci, C. Joblin, G. Mulas
We present an on-line database of computed molecular properties for a large sample of polycyclic aromatic hydrocarbons (PAHs) in four charge states: -1, 0, +1, and +2. At present o…
Theoretical evaluation of PAH dications properties
G. Malloci, C. Joblin, G. Mulas
Aims. We present a systematic theoretical study on 40 polycyclic aromatic hydrocarbons dications (PAHs++) containing up to 66 carbon atoms. Methods. We performed our calculations u…
A general model for the identification of specific PAHs in the far-IR
G. Mulas, G. Malloci, C. Joblin +1
Context. In the framework of the interstellar PAH hypothesis, far-IR skeletal bands are expected to be a fingerprint of single species in this class. Aims. A detailed model of the…
Diagnostics for specific PAHs in the far-IR: searching neutral naphthalene and anthracene in the Red Rectangle
G. Mulas, G. Malloci, C. Joblin +1
Context. In the framework of the interstellar polycyclic aromatic hydrocarbons (PAHs) hypothesis, far-IR skeletal bands are expected to be a fingerprint of single species in this c…
