Top panels: resulting radial profile of the DCO+ integrated intensity map of both models and data. The error bars on the data correspond to 3σ, where σ is calculated as the standard deviation of a single ellipsoid divided by the square root of the number of beams.Middle panels: models’ temperature profiles with contours at 19 and 30 K. Bottom panels: DCO+ abundance profiles over-plotted with temperature contours at 19 and 30 K. The hatched region in the DCO+ abundance from model CD marks the radial cutoff used in our standard model to reproduce the absence of emission at R > 300 AU.

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.
