Abstract

Water and methanol have been shown to form a stable clathrate hydrate under conditions of relevance to the interstellar medium [1]. Observational evidence indicates that methanol may be present in ices in proximity to protostars at local concentrations well above its overall solid state abundance, suggesting that segregation processes occur in such ices [2]. In previous research we have demonstrated the influence of water ice morphology on the desorption behaviour of other species adsorbed on, or mixed in water ice films [3, 4]. Using CO desorption as a probe, in combination with infrared spectroscopy, we present here the results of an extension of this experimental program, in which the influence of varying methanol concentrations on the morphology of water ice have been studied.
