Polycyclic aromatic hydrocarbon processing in interstellar shocks
Elisabetta R. Micelotta,Elisabetta R. Micelotta,Anthony P. Jones,Alexander G. G. M. Tielens,Alexander G. G. M. Tielens +4 more
TL;DR: In this article, the effects of energetic (≈0.01−1 keV) ion (H, He and C) and electron collisions on PAHs in interstellar shock waves were investigated.
Journal ArticleDOI
Polycyclic aromatic hydrocarbon processing in a hot gas
Elisabetta R. Micelotta,Elisabetta R. Micelotta,Anthony P. Jones,Alexander G. G. M. Tielens,Alexander G. G. M. Tielens +4 more
TL;DR: In this paper, the effects of energetic ion and electron collisions on PAHs in the hot post-shock gas behind interstellar shock waves were investigated, and it was shown that PAH destruction is dominated by He collisions at low temperatures (T < 3 × 10 4 K), and by electron collisions at higher temperatures.
Journal ArticleDOI
The formation of cosmic fullerenes from arophatic clusters
Elisabetta R. Micelotta,Anthony P. Jones,Jan Cami,Jan Cami,Els Peeters,Els Peeters,Jeronimo Bernard-Salas,Giovanni Fanchini +7 more
TL;DR: In this article, the formation of fullerenes from hydrogenated amorphous carbon (a-C:H or HAC) nanoparticles was studied in the circumstellar environments of young, carbon-rich planetary nebulae.
Journal ArticleDOI
On the Excitation and Formation of Circumstellar Fullerenes
Jeronimo Bernard-Salas,Jan Cami,Jan Cami,Els Peeters,Els Peeters,Anthony P. Jones,Elisabetta R. Micelotta,Martin Groenewegen +7 more
TL;DR: In this paper, the Spitzer mid-infrared spectrum of three fullerene-rich planetary nebulae in the Milky Way and the Magellanic Clouds was analyzed.
Journal ArticleDOI
Dust destruction by the reverse shock in the Cassiopeia A supernova remnant
TL;DR: In this paper, the authors used analytical models for the evolution of a supernova blast wave and of the reverse shock with special application to the clumpy ejecta of the remnant of Cassiopeia A (Cas A).
