Fig. 4


Water blend fluxes (top 15.17 μm, middle 17.22 μm, bottom 29.85 μm) divided by the local continuum flux versus 10 μm silicate feature peak strength. Diamonds are targets with crystalline dust features (F11.3/F9.8>0.71), crosses are for the amorphous grains. The color coding is based on the ratio F30/F13 reported in Oliveira et al. (2010). Magenta objects are flat disks (ratio below 1.5), cyan are flared objects, yellow are cold disks and brown are edge-on targets (ratio above 15). Black targets are the ones for which this ratio is not available. Arrows indicates upper limit measurements. The shaded pink boxes encircle the area covered in all of our models.

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.
