Collisional excitation of cyclopentadiene by helium. A complete set of rate coefficients and astrophysical applications

Sándor Demes, François Lique, Marcelino Agúndez +1

Complex organic molecules, including large cyclic species, are prevalent in interstellar space and play a key role in various astrochemical processes. Cyclopentadiene (c-C5H6) is a…

Hyperfine collisional excitation of ammonia by molecular hydrogen

J. Loreau, A. Faure, F. Lique +2

Ammonia is one of the most widely observed molecules in space, and many observations are able to resolve the hyperfine structure due to the electric quadrupole moment of the nitrog…

An accurate set of H $_{3}$ O $^{+} -$ H $_{2}$ collisional rate coefficients for non-LTE modelling of warm interstellar clouds

Sándor Demes, François Lique, Alexandre Faure +1

Hydronium (H $_{3}$ O $^{+}$ ) was first detected in 1986 in interstellar molecular clouds. It was reported in many galactic diffuse and dense regions, as well as in extragalactic sources.…
