Fig. 5
Modeled surface densities versus Z/H for SO, H2S, and CS in the case of Model C (C/O = 1.2, initial cloud H density of 2 × 105 cm-3 and age of 106 yr) at a radius of 300 AU. Top panel: MWC480, medium panel: LkCa15, bottom panel: GO Tau and DM Tau. Note that the cumulative column densities correspond to half of the column density values given in Fig. 4 because the vertical profiles are for half disks.
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.
