Analysis and calibration of CaII triplet spectroscopy of Red Giant Branch stars from VLT/FLAMES observations
G. Battaglia, M. Irwin, E. Tolstoy +4
We demonstrate that low resolution CaII triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual Red Giant Branch (RGB) stars in two nearby dwarf sph…
Stellar Population Gradients in Bulges along the Hubble Sequence: II. Relations with Galaxy Properties
P. Jablonka, J. Gorgas, P. Goudfrooij
We present the analysis of the radial gradients of stellar absorption lines in a sample of 32 bulges of edge-on spiral galaxies, spanning nearly the full Hubble sequence (from S0 t…
Stellar Population Gradients in Bulges along the Hubble Sequence: I. The Data
J. Gorgas, P. Jablonka, P. Goudfrooij
This is the first paper presenting our long-term project aimed at studying the nature of bulges through the analysis of their stellar population gradients. We present deep spectros…
The stellar population of bulges
P. Jablonka
This review summarizes the properties of the stellar population in bulges as observed in nearby or distant spiral galaxies. It gives a particular emphasis to the comparison with el…
