Abstract:
We have investigated the relevant trend of the bolometric correction
(BC) at the cool-temperature regime of red giant stars and its
possible dependence on stellar metallicity. Our analysis relies on a
wide sample of optical-infrared spectroscopic observations, along
the 3500Å=>2.5um wavelength range, for a grid of 92 red giant stars
in five (three globular + two open) Galactic clusters, along the full
metallicity range covered by the bulk of the stars,
-2.2≤[Fe/H]≤+0.4.
Description:
Spectroscopic observations of our stellar sample have been collected
during several runs between 2003 June and October at the 3.5-m
Telecopio Nazionale Galileo (TNG) of the Roque de los Muchachos
Observatory, at La Palma (Canary Islands, Spain).
