A new implementation of the infrared flux method using the 2MASS catalogue
<i>Context. <i/>The effective temperature scale of FGK stars, especially at the lowest metallicities remains a major problem in the chemical abundance analysis of metal-poor stars.<i>Aims. <i/>We present a new implementation of the infrared flux method (IRFM) using the 2MASS catalogue.<i>Methods. <i/>We computed the theoretical quantities in the 2MASS <i>JHK<i/><sub>s<sub/> filters …
