cds-question@unistra.frlate-type-starsdwarf-starsradio-sourcesinfrared-sourcesWe aim to increase the sample of ultracool dwarfs studied in the radio domain to allow a more statistically significant understanding of the physical conditions associated with these magnetically active objects. We conducted a volume-limited survey at 4.9GHz of 32 nearby ultracool dwarfs with spectral types covering the range M7-T8. A statistical analysis was performed on the combined data from the present survey and previous radio observations of ultracool dwarfs.2013A&A...549A.131Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/126/1526 : IR photometry of ultracool dwarfs (Bouy+, 2003)J/AJ/126/2421 : 2MASS-Selected sample of ultracool dwarfs (Cruz+, 2003)J/AJ/126/2449 : Nearby ultracool dwarfs in galactic plane (Reid+, 2003)J/A+A/416/655 : Ultracool dwarfs atomic lines in IR spectra (Lyubchik+ 2004)J/A+A/446/515 : Distances of nearby ultracool dwarfs (Phan-Bao+, 2006)J/AJ/133/439 : Luminosity function of M7-L8 ultracool dwarfs (Cruz+, 2007)J/AJ/133/2258 : Activity and kinematics of ultracool dwarfs (Schmidt+, 2007)J/MNRAS/382/515 : SDSS ultracool and halo WD candidates (Vidrih+, 2007)J/AJ/136/1290 : Ultracool dwarfs from the 2MASS (Reid+, 2008)J/A+A/493/L27 : Parallaxes of 10 ultracool subdwarfs (Schilbach+, 2009)J/ApJ/723/684 : NIRSPEC ultracool dwarf RV survey (Blake+, 2010)J/MNRAS/404/1817 : 2MASS/SDSS data for 806 ultracool dwarfs (Zhang+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A131https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/549/A131/tablea1 (Activity characteristics of all ultracool dwarfs observed at radio frequencies.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A131/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A131/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A131/tablea1?GETtext/xml+votable180.050000true162.0524292-11.33561940.0055555555555555566/221 360 399 483 496 544 672 1031 1357 2101 2149 2202 2502 2784 2978 4436 4515 4645 4719 4739 4768 4775 4813 4948 5264 5429 5666 6328 6613 6783 7220 7369 8361 8381 8402 8440 8723 8761 8794 8808 8874 8972 9009 9072 9113 9146 9449 9479 9569 9779 10169 10332 10676 10753 10850 11292 11336 11596 11639 11856 12152 13559 13885 14858 14910 15085 15651 16361 16568 16609 16873 17075 17283 17303 17530 17814 17985 18060 18155 18281 18300 18683 19680 19763 19857 19895 20713 20896 21209 21296 22148 22521 22535 22555 22681 22687 22739 22759 22851 22861 22950 23010 23144 23471 24566 24716 24824 24887 24897 25015 25100 25156 25266 25310 25411 25818 26020 26248 26282 26300 26447 26594 26699 27019 27058 27635 27648 28006 28344 28450 30505 30749 30833 30883 31009 31011 31062 31319 32426 32602 32650 34289 34535 34622 34660 34780 35020 35327 35499 35685 35902 35923 36418 36602 36640 36845 38322 40228 40297 40313 40332 40669 40882 40941 43966 44118 44226 44286 44456 44518 44603 44807 44954 45564 47012 48462 48957 49036 491393.2467741526420485e-24 3.2467741526420485e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A131?format=asciiInfraredRadiodefaultJ/A+A/549/A131/tablea1Activity characteristics of all ultracool dwarfs observed at radio frequencies.SimbadNameSimbad column added by the CDSmeta.idcharl_Lnu[<~] Limit flag on Lnumeta.code.errorcharFnu?
