The smoothness of the interstellar extinction curve in the UV. Comparison with recent laboratory measurements of PAH mixtures
Mathias Steglich, Yvain Carpentier, Cornelia Jäger +3
Context. As revealed by high-resolution spectral investigations in the wavelength range between 300 and 400 nm, the interstellar extinction curve does not display any of the sharp…
On the relevance of polyynyl-substituted PAHs to astrophysics
G. Rouillé, M. Steglich, Y. Carpentier +8
We report on the absorption spectra of the polycyclic aromatic hydrocarbon (PAH) molecules anthracene, phenanthrene, and pyrene carrying either an ethynyl (-C2H) or a butadiynyl (-…
Abundances of PAHs in the ISM: Confronting Observations with Experimental Results
R. Gredel, Y. Carpentier, G. Rouille +3
We present recent UV laboratory spectra of various polycyclic aromatic hydrocarbons (PAHs) and explore the potential of these molecules as carriers of the DIBs. From a detailed com…
Statistical universal branching ratios for cosmic ray dissociation, photodissociation, and dissociative recombination of the C(n=2-10), C(n=2-4)H and C3H2 neutral and cationic species
M. Chabot, T. Tuna, K. Beroff +9
Fragmentation branching ratios of electronically excited molecular species are of first importance for the modeling of gas phase interstellar chemistry. Despite experimental and th…
Fragmentation branching ratios of highly excited hydrocarbon molecules CnH and their cations CnH+ (n<4)
T. Tuna, M. Chabot, T. Pino +12
We have measured fragmentation branching ratios of neutral CnH and CnH+ cations produced in high velocity (4.5 a.u) collisions between incident CnH+ cations and helium atoms. Elect…
Discovery of Solar Rieger Periodicities in Another Star
M. Massi, J. Neidhoefer, Y. Carpentier +1
The Rieger periods are solar cycles with a time scale of months, which are present in both flaring activity and sunspot occurrence. These short-term periodicities, tentatively expl…
