Regions of different metallicity have been identified in the Magellanic Clouds by using the ratio between Asymptotic Giant Branch stars of spectral type C and M. In the Large Magellanic Cloud the ratio appears to decrease radially while in the Small Magellanic Cloud (SMC) there is no clear trend, reflecting either the large extension of the SMC along the line of sight or a more complex star formation history. The distribution of the C/M ratio is clumpy and corresponds to a spread in (Fe/H) of 0…

Is there a metallicity gradient in the Large Magellanic Cloud
A small but significant radial gradient in the mean periods of Large Magellanic Cloud (LMC) RR Lyrae variables is established from the OGLE-III survey data. This is interpreted as a metallicity

Abstract In this review we address the progress that has been made toward the understanding of Magellanic Cloud planetary nebulae (PNe) and their evolution since the last Magellanic Cloud Symposium.
Variable stars in the Magellanic Clouds – II. The data and infrared properties
The data of 8852 and 2927 variable stars detected by the OGLE survey in the Large and Small Magellanic Clouds are presented. They are cross-identified with the SIRIUS JHK survey data, and their
Red giant stars in the large magellanic cloud clusters
We present deep J, H, and Ks photometry and accurate color magnitude diagrams down to K ≈ 18.5 for a sample of 13 globular clusters in the Large Magellanic Cloud. This data set combined with the
The Chemical Enrichment History of the Large Magellanic Cloud
Ca II triplet spectroscopy has been used to derive stellar metallicities for individual stars in four Large Magellanic Cloud fields situated at galactocentric distances of 3°, 5°, 6°, and 8° to the
AGB stars as tracers of metallicity and mean age across M 33
Maps showing the distribution of mean age and metallicity obtained from the Ks method suggest that: the outer galaxy disc/halo is metal poorer than the nuclear region and metal-rich clumps in the inner galaxy change location with time.
Long period variables detected by ISO in the Small Magellanic Cloud
This article presents the study of the light-curves extracted from the MACHO database of a sample of stars observed by the Infrared Space Observatory in the Small Magellanic Cloud. These stars belong
AGB Stars in the Local Group, and Beyond
Carbon stars are tracers of the intermediate age population in galaxies. Either they are currently undergoing third dredge-up on the (Thermal-Pulsing) Asymptotic Giant Branch (TP-AGB) – the cool and


The Large Magellanic Cloud Bar West field
Infrared photometry is presented for an unbiased sample of M giants in the Bar West field of the LMC. The m(bol), J-K color-magnitude diagram is dominated by AGB stars with properties similar to
