Notes. (a)N=No; Y=Yes. Clustered regions have 34 YSO pc−1, while non-clustered regions have 6 YSO pc−1 (Plunkett et al. 2013). (b)Systems from the sample in the pilot paper Murillo et al. (2018a). (c)Only included in the DCO+ J =1-0 Nobeyama data sample. (d)Reynolds et al. (2024) raise the possibility that IRAS 03282+3035 is not a close binary given recent observations, but cannot confirm. But given the results of the current work, there is no difference in classifying the system as a single or close binary in terms of physical parameters.

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.
