Full spectral fitting of Milky Way and M31 globular clusters: ages and metallicities

Enio Cezario, Paula R. T. Coelho, Alan Alves-Brito +2

Context: The formation and evolution of disk galaxies are long standing questions in Astronomy. Understanding the properties of globular cluster systems can lead to important insig…

Fluorine variations in the globular cluster NGC 6656 (M22): implications for internal enrichment timescales

Valentina D'Orazi, Sara Lucatello, Maria Lugaro +8

Observed chemical (anti)correlations in proton-capture elements among globular cluster stars are presently recognized as the signature of self-enrichment from now extinct, previous…

A kinematic study of planetary nebulae in the dwarf irregular galaxy IC10

Denise R. Gonçalves, Ana M. Teodorescu, Alan Alves-Brito +2

We present positions, kinematics, and the planetary nebula luminosity function (PNLF) for 35 planetary nebulae (PNe) in the nearest starburst galaxy IC10 extending out to 3kpc from…

CNO and F abundances in the globular cluster M22 (NGC 6656)

Alan Alves-Brito, David Yong, Jorge Meléndez +2

Recent studies have confirmed the long standing suspicion that M22 shares a metallicity spread and complex chemical enrichment history similar to that observed in Omega Cen. M22 is…

Abundance trends in the inner and outer Galactic disk

T. Bensby, A. Alves-Brito, M. S. Oey +2

Based on high-resolution spectra obtained with the MIKE spectrograph on the Magellan telescopes we present detailed elemental abundances for 64 red giant stars in the inner and out…
