cds-question@unistra.frdwarf-starslate-type-starsinfrared-astronomyspectroscopyAt young ages, low surface gravity affects the atmospheric properties of ultracool dwarfs. The impact on medium-resolution near-infrared (NIR) spectra has only been slightly investigated at the M-L transition sofar. We present a library of near-infrared (1.1-2.45um) medium-resolution (R~1500-2000) integral field spectra of 15 young M6-L0 dwarfs. We aim at deriving updated NIR spectral type, luminosity and physical parameters (Teff, logg, M, L/L_{sun}_) of each source. This work also aims at testing the latest generation of BT-SETTL atmospheric models. We estimated spectral types using spectral indices and spectra of reference young objects classified in the optical. We used the 2010 and 2012 releases of the BT-SETTL synthetic spectral grid and cross-checked the results with the DRIFT-PHOENIX models to derive the atmospheric properties of the sources.2014A&A...562A.127Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/562/A127CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/503/639 : NIR spectral of M-T dwarfs (Testi, 2009)J/AJ/131/2722 : New L and T dwarfs from the SDSS (Chiu+, 2006)J/A+A/542/A33 : 3 M dwarfs near-infrared spectra (Onehag+, 2012)J/AJ/144/99 : Near-IR spectroscopy of 36 late M dwarfs (Deshpande+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/562/A127https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/562/A127http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/562/A127https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/562/A127https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/562/A127http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/562/A127GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/562/A127/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/562/A127/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/562/A127/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/562/A127/stars?GETtext/xml+votable180.050000true167.3067917-77.57905560.0055555555555555566/496 1074-1075 5413 24580 25864 34909 35202 36956-36957 38054 38359 39044 44402 47205https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/562/A127?format=asciiInfrareddefaultJ/A+A/562/A127/starsList of studied starsrecnoRecord number assigned by the VizieR team.
