Water ice deposition and growth in molecular clouds

Abstract: In interstellar clouds the deposition of water ice onto grains only occurs at visual extinctions above some threshold value (Ath). At extinctions greater than Ath there is a (near-linear) correlation between the inferred column density of the water ice and AV. For individual cloud complexes such as Taurus, Serpens and ρ-Ophiuchi, Ath and the gradients of the correlation are very similar along all lines of sight. We have investigated the origin of this phenomenon, with careful consideration of the various possi… Show more

“…The model is based on a simple one-point, dynamically static, application of the STARCHEM model that we have used in other studies (e.g. Rawlings & Williams 2021 ). For the purpose of our study, we assume that the system is well-evolved and in chemical quasi-equilibrium, which is consistent with our understanding of the conditions within dense cores and pre-stellar star-forming regions (e.g.…”
