We derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the Infrared Flux Method to multiband photometry. Our study is based on 104 stars for which we have excellent BV(RI)CJHKS photometry, excellent parallaxes and good metallicities. Colours computed from the most recent synthetic libraries (ATLAS9 and MARCS) are found to be in good agreement with the empirical colours in the optical bands, but some… 
M dwarfs: effective temperatures, radii and metallicities
We empirically determine effective temperatures and bolometric luminosities for a large sample of nearby M dwarfs, for which high accuracy optical and infrared photometry is available. We introduce a

Stellar parameters are not easily derived from M dwarf spectra, which are dominated by complex bands of diatomic and triatomic molecules and not well described at the line by line level by
Infrared flux method and colour calibrations
The Infrared Flux Method (IRFM) is one of the most accurate techniques to derive fundamental stellar parameters – namely effective temperatures, bolometric luminosities and angular diameters – in an

Context. The use of model atmospheres for deriving stellar fundamental parameters, such as Teff ,l ogg ,a nd [Fe/H], will increase as we find and explore extreme stellar populations where empirical

Effective Temperatures of Low-mass Stars from High-resolution H-band Spectroscopy
High-resolution, near-infrared spectra will be the primary tool for finding and characterizing Earth-like planets around low-mass stars. Yet, the properties of exoplanets cannot be precisely
Precise and accurate parameters for late-type (late K and M) dwarf stars are important for characterization of any orbiting planets, but such determinations have been hampered by these stars’ complex
