Abstract: Carbon dioxide (CO 2 ) is one of the most relevant and abundant species in astrophysical and atmospheric media. In particular, CO 2 ice is present in several solar system bodies, as well as in interstellar and circumstellar ice mantles. The amount of CO 2 in ice mantles and the presence of pure CO 2 ice are significant indicators of the temperature history of dust in protostars. It is therefore important to know if CO 2 is mixed with other molecules in the ice matrix or segregated and whether it is present in … Show more

“…Approximately two thirds of the observed solid CO 2 is found in a water-rich environment, while one third is detected in a CO environment. Pure and crystalline CO 2 ice, such as the one used in our experimental simulations (Escribano et al 2013), is also observed. It may be formed by segregation from the water-rich environment or through evaporation of the CO from the CO:CO 2 component (Pontoppidan et al 2008).…”

“…This lack of splitting in Gerakines & Hudson (2015) disagrees with both Escribano et al (2013) and Isokoski et al (2013). Since these three groups used different thickness of CO2 ice, it remains a question whether the difference among them is due to the difference in ice thickness and/or deposition rate (Escribano et al (2013) used a slightly slower deposition rate than Gerakines & Hudson (2015)). In this work we study systematically how the CO2 ice crystallization depends on both ice thickness and temperature.…”

“…Furthermore, there is some disagreement on the results and their interpretation. Escribano et al (2013) used theoretical modeling and laboratory measurements using both RAIRS and transmission spectroscopy to study the crystallization of pure CO2 ice. They found that even for CO2 ice deposited when the substrate is at 8 K, as long as the ice film is not too thin, the ice is partly crystalline.…”

“…The properties of individual molecular componentes of interstellar ice analogs have been studied over the years (e.g., Sandford et al 1988;Sandford & Allamandola 1990;Gerakines et al 1996;Escribano et al 2013). Our VUV-absorption spectra can be directly applied to astrophysical icy environments practically made of a single compound, for example, either CO 2 or H 2 O largely dominate the composition of different regions at the south pole of Mars (Bibring et al 2004).…”
