| We surveyed embedded protostars in nearby clouds (Corona Australis, Aquila, Chamaeleon I & II, Ophiuchus, Serpens) with the Atacama Large Millimeter/submillimeter Array at 1.3mm with a resolution of 0.1¨. We detected 184 protostellar disks, 90 of which were observed at a resolution of 14-18 au, making it one of the most comprehensive high-resolution disk samples from early protostellar evolutionary stages. I will show our first results with the continuum ALMA data, including trends in companions and on disk sizes and substructures as a function of early evolutionary stage as traced by the bolometric temperatures. I will show simple limits to the frequency young substellar companions from the CAMPOS survey, hoping to lead to discussion of implications about possible brown dwarf formation from disks, streamers, or direct fragmentation. |
