cds-question@unistra.frlate-type-starsradio-continuum-emissioninfrared-photometrystellar-spectral-typesWe present a new radio survey of about 100 late-M and L dwarfs undertaken with the Very Large Array. The sample was chosen to explore the role of rotation in the radio activity of ultracool dwarfs. As part of the survey we discovered radio emission from three new objects, 2MASS J0518113-310153 (M6.5), 2MASS J0952219-192431 (M7), and 2MASS J1314203+132001 (M7), and made an additional detection of LP 349-25 (M8). Combining the new sample with results from our previous studies and from the literature, we compile the largest sample to date of ultracool dwarfs with radio observations and measured rotation velocities.2012ApJ...746...23Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/746/23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/549/A131 : Radio survey of ultracool dwarfs (Antonova+, 2013)J/MNRAS/404/1817 : 2MASS/SDSS data for 806 ultracool dwarfs (Zhang+, 2010)J/ApJ/701/1922 : Radio interferometric planet search.
