The Metallicity Distribution and Its Gradients in the LMC via Calcium Triplet Spectroscopy
We present a new calibration of the CaII triplet as metallicity indicator based in 4 globular and 11 open clusters which cover a range of metallicity - 2≤[Fe/H]...
The Metallicity Distribution Function of the Halo of the Milky Way
We report on the distribution of metallicities, [Fe/H], for very metal-poor stars in the halo of the Galaxy. Although the primary information on the nature of...
The Metallicity Distribution of the Milky Way's Stellar Halo
SDSS DR6 includes about 300,000 stellar spectra, and a significant fraction of them belong to members of the halo. We make use of these data to examine closely...
The Metallicity Planet Correlation In The Harps Volume Limited Sample
To understand the formation and evolution of solar-type stars and planets in the solar neighborhood, we need to obtain their stellar parameters with high...
The Mg/Fe characterization of the MILES library for stellar populations studies
We have obtained [Mg/Fe] for around 77% of the stars of the MILES library of stellar spectra in order to include this important information into simple stellar...
The spectral lines observed in penumbrae are asymmetrical, revealing the existence of spatially unresolved structures. We infer their physical properties by...
