The Chemical Enrichment History of the Magellanic Clouds Field Populations
R. Carrera, C. Gallart, A. Aparicio +5
We report the results of our project devoted to study the chemical enrichment history of the field population in the Magellanic Clouds using Ca II triplet spectroscopy.
The Chemical Enrichment History of the Small Magellanic Cloud and Its Gradients
Ricardo Carrera, Carme Gallart, Antonio Aparicio +3
We present stellar metallicities derived from Ca II triplet spectroscopy in over 350 red giant branch stars in 13 fields distributed in different positions in the SMC, ranging from…
The Chemical Enrichment History of the Large Magellanic Cloud
Ricardo Carrera, Carme Gallart, Eduardo Hardy +2
Ca II triplet spectroscopy has been used to derive stellar metallicities for individual stars in four LMC fields situated at galactocentric distances of 3\arcdeg, 5\arcdeg, 6\arcde…
Tracing out the Northern Tidal Stream of the Sagittarius Dwarf Spheoridal Galaxy
D. Martinez-Delgado, M. A. Gomez-Flechoso, A. Aparicio +1
The main aim of this paper is to report two new detections of tidal debris in the northern stream of the Sagittarius dwarf galaxy located at 45 arcdeg and 55 arcdeg from the center…
The Star Formation History and the spatial distribution of stellar populations in the Ursa Minor Dwarf Spheroidal Galaxy
R. Carrera, A. Aparicio, D. Martinez-Delgado +1
As a part of a project devoted to the study of the Ursa Minor dSph, the star formation history of the galaxy is presented in this paper. The analysis uses wide field photometry, en…
The Star Formation History and the Morphological Evolution of the Draco Dwarf Spheroidal Galaxy
A. Aparicio, R. Carrera, D. Martinez-Delgado
The photometric and morphological properties, as well as the star formation history, of the Draco dwarf spheroidal galaxy are analyzed on the basis of wide field, CCD photometry of…
