cds-question@unistra.frbrown-dwarfsstellar-distanceBrown dwarfs are the bridge between low-mass stars and giant planets. One way of shedding light on their dominant formation mechanism is to study them at the earliest stages of their evolution, when they are deeply embedded in their parental clouds. Several works have identified pre- and proto-brown dwarf candidates using different observational approaches. The aim of this work is to create a database of all the objects classified as very young substellar candidates in the literature in order to study them homogeneously. We gathered all the information about very young substellar candidates available in the literature until 2020. We retrieved their published photometry from the optical to the centimetre regime, and we wrote our own codes to derive their bolometric temperatures and luminosities, and their internal luminosities. We also populated the database with other parameters extracted from the literature, such as the envelope masses, their detection in some molecular species, and the presence of outflows. The result of our search is the SUbstellar CANdidates at the Earliest Stages (SUCANES) database, containing 174 objects classified as potential very young substellar candidates in the literature. We present an analysis of the main properties of the retrieved objects. Since we updated the distances to several star forming regions, we were able to reject some candidates based on their internal luminosities. We also discuss the derived physical parameters and envelope masses for the best substellar candidates isolated in SUCANES. As an example of a scientific exploitation of this database, we present a feasibility study for the detection of radio jets with upcoming facilities: the next generation Very Large Array and the Square Kilometer Array interferometers. The SUCANES database is accessible through a graphical user interface, and it is open to any potential user.2025A&A...695A..13Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/695/A13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/695/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/695/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/695/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/695/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/695/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/695/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/695/A13/tableb1 (The targets included in the SUCANES data base)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/695/A13/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/695/A13/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/695/A13/tableb1?GETtext/xml+votable180.050000true51.289583330.39758330.0055555555555555566/857-860 862 881 1048 1052 1054 1072 1074-1075 1080 1082 1136 1157 1159 1168-1170 1231 1264 1266 1539 1636 14031 14052-14053 15426 15588 15965 16129 16131 16196-16197 16225 21400 21425 21436 21438 22805 22848 22851 22854 23533 23560 23738-23739 29112 29191 29658-29659 29662 30254-30255 30340-30341 30343-30344 30354 30359 30361 30363 30366 30621 36956-36957 39370 41120 41132 41134 41822 42598 42611 42614 42727 42736-42738 42744 42746 42970 42981 42989 42992 47742https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/695/A13?format=asciidefaultJ/A+A/695/A13/tableb1The targets included in the SUCANES data baserecnoRecord number assigned by the VizieR team.
