In this work we have investigated the relevant trend of the bolometric correction (BC) at the cool-temperature regime of red giant stars and its possi ble dependence on stellar metallicity. Our analysis relies on a wide sample of optical-infrare d spectroscopic observations, along the 3500 ˚ A ) 2.5µm wavelength range, for a grid of 92 red giant stars in five (3 gl obular + 2 open) Galactic clusters, along the full metallicity rang e covered by the bulk of the stars, −2.2 6 [Fe/H] 6 +0.4… 
Stellar lifetime and ultraviolet properties of the old metal-rich Galactic open cluster NGC6791: a pathway to understand the UV upturn of elliptical galaxies
The evolutionary properties of the old metal-rich Galactic open cluster NGC6791 are assessed, based on deep UB photometry and 2Mass JK data. For 4739 stars in the cluster, bolometric luminosity and
Properties of carbon stars in the solar neighbourhood based on Gaia DR2 astrometry
We find that the combined LF of N- and SC-type stars are consistent with a Gaussian distribution peaking at M_bol~ -5.2 mag. The resulting LF however shows two tails at lower and higher luminosities

Chemical analysis of the bulge globular cluster NGC 6553
Globular Clusters are among the oldest objects in the Galaxy, thus their researchers are key to understanding the processes of evolution and formation that the galaxy has experienced in early stages.
Spectroscopic and Interferometric Measurements of Nine K Giant Stars
We present spectroscopic and interferometric measurements for a sample of nine K giant stars. These targets are of particular interest because they are slated for stellar oscillation observations.
