Confirmed class 0 sources list
Listed in IVOA Registry (Virtual Observatory)
We searched the literature to obtain a complete list of known Class 0 sources.
Description
A list of 95 confirmed or candidate objects was compiled. To the best of our knowledge, all published broadband observations from 1{mu}m to 3.5mm have been collected and are assembled in a catalog.
These data were used to determine physical properties (T_bol_, L_bol_, L_smm_/L_bol_, M_env_) and for a uniform classification. Fifty sources possess sufficient observational data and are classified as Class 0 or Class 0/1 objects. The source properties are compared with different evolutionary models to infer ages and masses, and their correlations are investigated.

About 25% of the sources are found to be in a quiet accretion phase or possess a significantly different time evolution of the accretion rate than the average. In Taurus, with its isolated star formation mode, this seems especially to be the case.
