cds-question@unistra.frdwarf-starsstellar-spectral-typesvisible-astronomysloan-photometryinfrared-photometryWide-band photometrytrigonometric-parallaxstellar-agesWe combine optical, near-infrared, and mid-infrared spectra and photometry to construct expanded spectral energy distributions for 145 field age (>500 Myr) and 53 young (lower age estimate <500 Myr) ultracool dwarfs (M6-T9). This range of spectral types includes very low mass stars, brown dwarfs, and planetary mass objects, providing fundamental parameters across both the hydrogen and deuterium burning minimum masses for the largest sample assembled to date. A subsample of 29 objects have well constrained ages as probable members of a nearby young moving group. We use 182 parallaxes and 16 kinematic distances to determine precise bolometric luminosities (L_bol_) and radius estimates from evolutionary models give semi-empirical effective temperatures (T_eff_) for the full range of young and field age late-M, L, and T dwarfs. We construct age-sensitive relationships of luminosity, temperature, and absolute magnitude as functions of spectral type and absolute magnitude to disentangle the effects of degenerate physical parameters such as T_eff_, surface gravity, and clouds on spectral morphology. We report bolometric corrections in J for both field age and young objects and find differences of up to a magnitude for late-L dwarfs. Our correction in Ks shows a larger dispersion but not necessarily a different relationship for young and field age sequences. We also characterize the NIR-MIR reddening of low gravity L dwarfs and identify a systematically cooler T_eff_ of up to 300 K from field age objects of the same spectral type and 400 K cooler from field age objects of the same M_H_ magnitude.2015ApJ...810..158Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/810/158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/238 : Yale Trigonometric Parallaxes, Fourth EditionII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)B/denis : The DENIS database (DENIS Consortium, 2005)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/328 : AllWISE Data Release (Cutri+ 2013)J/AJ/103/638 : USNO Photographic Parallaxes.
