Table 1

Initial abundances of molecules in our chemical grid.

Species Abundance

H2 1.00(0)
CO 1.57(−4)
H2Oice 2.03(−4)
N2 4.94(−5)

Notes. The notation a(b) means a × 10b. Abundances are given relative to H2. Initial abundances of elements present in the UMIST06 database but not listed in this table are as in Aikawa et al. (2008) and Bruderer et al. (2009).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
