Abstract:
The infrared flux method (IRFM) has been applied to a sample of 135
dwarf and 36 giant stars covering the following regions of the
atmospheric parameter space: (1) the metal-rich ([Fe/H]≳0) end
(consisting mostly of planet-hosting stars), (2) the cool
(Teff≲5000K) metal-poor (-1≲[Fe/H]≲-3) dwarf region, and
(3) the very metal-poor ([Fe/H]≲-2.5) end.
