cds-question@unistra.frmultiple-starsThe frequency of multiple systems and their properties are key constraints of stellar formation and evolution. Formation mechanisms of very low-mass (VLM) objects are still under considerable debate, and an accurate assessment of their multiplicity and orbital properties is essential for constraining current theoretical models. Taking advantage of the virtual observatory capabilities, we looked for comoving low and VLM binary (or multiple) systems using the Large Area Survey of the UKIDSS LAS DR10, SDSS DR9 and the 2MASS Catalogues. Other catalogues (WISE, GLIMPSE, SuperCosmos, etc.) were used to derive the physical parameters of the systems. We report the identification of 36 low and VLM (~M0-L0 spectral types) candidates to binary/multiple system (separations between 200 and 92000au), whose physical association is confirmed through common proper motion, distance and low probability of chance alignment. This new system list notably increases the previous sampling in their mass-separation parameter space (~100). We have also found 50 low-mass objects that we can classify as ~L0-T2 according to their photometric information. Only one of these objects presents a common proper motion high-mass companion. Although we could not constrain the age of the majority of the candidates, probably most of them are still bound except four that may be under disruption processes. We suggest that our sample could be divided in two populations: one tightly bound wide VLM systems that are expected to last more than 10 Gyr, and other formed by weak bound wide VLM systems that will dissipate within a few Gyr.2017MNRAS.466.2983Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/466/2983CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)V/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/466/2983https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/466/2983http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/466/2983https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/466/2983https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/466/2983http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/466/2983GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/466/2983/table2 (Candidate position data for group B (2MASS, SDSS and WISE))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/2983/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/2983/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/2983/table2?GETtext/xml+votable180.050000true145.29913533.253631940.005555555555555556Cone search capability for table J/MNRAS/466/2983/table1 (Candidate position data for group A (2MASS, SDSS and UKIDSS))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/2983/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/2983/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/2983/table1?GETtext/xml+votable180.050000true9.687476945.316770.005555555555555556Cone search capability for table J/MNRAS/466/2983/table5 (Physical properties of the identified higher mass tertiaries to the M-M systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/2983/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/2983/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/2983/table5?GETtext/xml+votable180.050000true29.8543088911.281106110.005555555555555556Cone search capability for table J/MNRAS/466/2983/tablea1 (L-T candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/466/2983/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/466/2983/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/466/2983/tablea1?GETtext/xml+votable180.050000true1.5937811113.012551110.0055555555555555566/27 72 4119 4127 4384 4559 4783 4810 4959 5027 5029 5168 5632 5641 5644 8693 8713 8728 9274 9363 9372 9416 10244 10311 10319 10341 10363 10365 10372 10376 10384 10389 10469-10471 10540 17899 17904 18149 18151 18167 18170 18264 18271 18292 18324 18397 18867 18869 18892 19221 19224 19238 19300 19554 19617 19623 19639 19655 19993 21841 21977 25928 26107 26174 26410 26428 26433 26443 26482 26506 26534 26567 26602 26847 26993 27023 27090 27365 27391 27459 27486 27572 27588 27823 27847 27867 27974 28024 28116 28118 28165 28190 28200-28201 28205 28232 28305 29512 31397 40951 491511.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/466/2983?format=asciidefaultJ/MNRAS/466/2983/table2Candidate position data for group B (2MASS, SDSS and WISE)recnoRecord number assigned by the VizieR team.
