Mutual neutralization of C $_{60}^{+}$ and C $_{60}^{-}$ ions: Excitation energies and state-selective rate coefficients

Michael Gatchell, Raka Paul, MingChao Ji +6

Context: Mutual neutralization between cations and anions play an important role in determining the charge-balance in certain astrophysical environments. However, empirical data fo…

Resilience of small PAHs in interstellar clouds: Efficient stabilization of cyanonaphthalene by fast radiative cooling

Mark H. Stockett, James N. Bull, Henrik Cederquist +6

After decades of speculation and searching, astronomers have recently identified specific Polycyclic Aromatic Hydrocarbons (PAHs) in space. Remarkably, the observed abundance of cy…

Failure of hydrogenation in protecting polycyclic aromatic hydrocarbons from fragmentation

Michael Gatchell, Mark H. Stockett, Nathalie de Ruette +13

A recent study of soft X-ray absorption in native and hydrogenated coronene cations, C $_{24}$ H $_{12 + m}^{+}$ $m = 0 - 7$ , led to the conclusion that additional hydrogen atoms protect (int…
