cds-question@unistra.frstellar-radiiinterferometryinfrared-photometryvisible-astronomymedium-band-photometrylate-type-starsWe present interferometric angular diameter measurements of 21 low-mass, K- and M-dwarfs made with the CHARA Array. This sample is enhanced by adding a collection of radius measurements published in the literature to form a total data set of 33 K-M-dwarfs with diameters measured to better than 5%. We use these data in combination with the Hipparcos parallax and new measurements of the star's bolometric flux to compute absolute luminosities, linear radii, and effective temperatures for the stars. We develop empirical relations for ~K0 to M4 main-sequence stars that link the stellar temperature, radius, and luminosity to the observed (B-V), (V-R), (V-I), (V-J), (V-H), and (V-K) broadband color index and stellar metallicity [Fe/H]. These relations are valid for metallicities ranging from [Fe/H]=-0.5 to +0.1dex and are accurate to ~2%, ~5%, and ~4% for temperature, radius, and luminosity, respectively. Our results show that it is necessary to use metallicity-dependent transformations in order to properly convert colors into stellar temperatures, radii, and luminosities.2012ApJ...757..112Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/757/112CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/137 : Extended Hipparcos Compilation (XHIP) (Anderson+, 2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/237 : Stellar Photometry in Johnson's 11-color system (Ducati, 2002)II/215 : uvby-beta Catalogue (Hauck+ 1997)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)II/168 : Homogeneous Means in the UBV System (Mermilliod 1991)II/5 : UBV Photometry of Bright Stars (Johnson+ 1966)J/ApJ/748/93 : K-band spectra for 133 nearby M dwarfs (Rojas-Ayala+, 2012)J/ApJ/746/101 : Diameters and temperatures of AFG stars (Boyajian+, 2012)J/A+A/544/A114 : 1RXS J180431.1-273932 optical identification (Masetti+, 2012)J/PAZh/37/924 : 1RXS J073346.0+261933 light curve (Denisenko+, 2011)J/ApJ/742/123 : Photometry and Velocity of LSPM J1112+7626 (Irwin+, 2011)J/ApJ/728/48 : Multicolor eclipse data for 6 new binaries (Kraus+, 2011)J/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/ApJ/721/412 : Polar CV* 1RXS J173006.4+033813 phot.
