Fig. 13


Mass-luminosity distribution of the whole sample. The gray tracks are evolutionary models used by Molinari et al. (2008). The dash-dotted colored lines show a linear fit to the corresponding class of sources. The horizontal dashed line shows the luminosity of a B1.5 star as calculated by Mottram et al. (2011a, Table 1), whereas the vertical dashed line shows the threshold of 650 M beyond which clumps are likely to host massive dense clumps or high-mass protostars (Csengeri et al. 2014).

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.
