We derive a B-V color-temperature relation for stars in the least model-dependent way employing the best modern data. The fit we obtained with the form Teff = Teff{(B-V)0, [Fe/H], log g} covers stars in the range F0–K5 with metallicity [Fe/H] = -1.5 to +0.3 for both dwarfs and giants. The fit is well constrained, and the residual temperature of the fit is 62 K, which is consistent with what is expected from the quality of the input data. Metallicity and surface gravity effects are well… 
The Effective Temperature Scale of FGK Stars. II. Teff:Color:[Fe/H] Calibrations
We present up-to-date metallicity-dependent temperature versus color calibrations for main-sequence and giant stars based on temperatures derived with the infrared flux method (IRFM). Seventeen
Empirically Constrained Color-Temperature Relations. II. uvby
A new grid of theoretical color indices for the Stromgren uvby photometric system has been derived from MARCS model atmospheres and SSG synthetic spectra for cool dwarf and giant stars having -3.0 ≤
A Constraint on Z☉ from Fits of Isochrones to the Color-Magnitude Diagram of M67
The mass at which a transition is made between stars that have radiative or convective cores throughout the core H burning phase is a fairly sensitive function of Z (particularly, the CNO
Accurate fundamental parameters for lower main‐sequence stars
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
The determination of Teff for metal-poor A-type stars using V and 2MASS J, H and K magnitudes
Effective temperatures ( T eff ) can be determined from $(V-J)_{\rm 0}$, $(V-H)_{\rm 0}$  and $(V-K)_{\rm 0}$ colours that are derived from 2MASS magnitudes. This gives another way to estimate the T
New Analyses of Star-to-Star Abundance Variations among Bright Giants in the Mildly Metal-poor Globular Cluster M5
We present a chemical composition analysis of 36 giant stars in the mildly metal-poor ([Fe/H] = -1.21) globular cluster M5 (NGC 5904). The analysis makes use of high-resolution data acquired for 25
Empirically Constrained Color-Temperature Relations. I. BV(RI)C
This investigation presents a set of transformations to Johnson B-V, Cousins V-R, and Cousins V-I, as well as bolometric corrections to V, for [Fe/H] = -3, -2, -1, -0.5, 0.0, and +0.3 and, in each
Applicability of colour index calibrations to T Tauri stars
We examine the applicability of effective temperature scales of several broad band colours to T Tauri stars (TTS).We take into account different colour systems as well as stellar parameters like
Lithium abundances for early F stars: new observational constraints for the Li dilution
Aims. To investigate any correlation between Li abundances and rotational velocities among F–G evolved stars, we study a large sample of early F stars from the Bright Star Catalogue (BSC), most of
The multiplicity of the subgiant branch of ω centauri : Evidence for prolonged star formation
We combine spectroscopic and photometric data for subgiant stars of ω Cen to extract results that neither data set could have provided on its own. GIRAFFE@VLT spectra of 80 stars at R = 6400 give
