Silicate cosmic dust grain collisions in the interstellar medium: A molecular dynamics study
C. J. Esmerian, S. R. Hashemi, W. M. C. Sameera +6
(abridged) We aim to predict the most important parameters for grain-grain collision outcomes for models of interstellar grain population evolution on astrophysical scales: the thr…

The Binding Energies of Atoms on Amorphous Silicate Dust: A Computational Study
Kristoffer Hansson, W. M. C. Sameera, Clarke J. Esmerian +6
Context. We investigate the binding energies of atoms to interstellar dust particles, which play a key role in their growth and evolution, as well as for the chemical reactions on…

Chemical pathways of SO2 with hydrogen atoms on interstellar ice analogues
Thanh Nguyen, Yasuhiro Oba, W. M. C. Sameera +2
Sulfur dioxide (SO2) is a sulfur-containing molecule expected to exist as a solid in the interstellar medium (ISM). In this study, we performed laboratory experiments and computati…
