Synchronization mechanism of sharp edges in rings of Saturn

D. L. Shepelyansky, A. S. Pikovsky, J. Schmidt +1

We propose a new mechanism which explains the existence of enormously sharp edges in the rings of Saturn. This mechanism is based on the synchronization phenomenon due to which the…

[SiPAH]+ pi-Complexes in the Interstellar Medium

B. Joalland, A. Simon, C. J. Marsden +1

We investigate the presence of silicon atoms adsorbed on the surface of interstellar polycyclic aromatic hydrocarbons (PAHs) to form SiPAH pi-complexes. We use quantum chemistry ca…

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…

Wave chaos in rapidly rotating stars

F. Lignieres, B. Georgeot

Effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We study the dynamics of acoustic rays in rotating polytropic stars and show using quantum ch…

Formation and destruction of polycyclic aromatic hydrocarbon clusters in the interstellar medium

M. Rapacioli, F. Calvo, C. Joblin +3

The competition between the formation and destruction of coronene clusters under interstellar conditions is investigated theoretically. The unimolecular nucleation of neutral clust…
