The NIR Ca II triplet at low metallicity Searching for extremely low-metallicity stars in classical dwarf galaxies

The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better understanding of metallicities of stars in the Milky Way and dwarf galaxies ...

Resolving The Stellar Outskirts Of M81: Evidence For A Faint, Extended Structural Component

Pascale Jablonka

We present a wide field census of resolved stellar populations in the northern half of M81, conducted with Suprime-Cam on the 8 m Subaru telescope and covering an area similar to 0.3 deg(2). The resulting color-magnitude diagram reaches over one magnitude ...

Evidence for metallicity spreads in three massive M31 globular clusters

Pascale Jablonka, Georges Meylan

Aims. We quantify the intrinsic width of the red giant branches of three massive globular clusters in M31 in a search for metallicity spreads within these objects. ...

Analysis and calibration of CaII triplet spectroscopy of red giant branch stars from VLT/FLAMES observations

Pascale Jablonka

We demonstrate that low-resolution Ca II triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual red giant branch (RGB) stars in two nearby dwarf spheroidal galaxies (dSphs) agree to +/- 0.1-0.2 dex with detailed high-resolu ...

Red giants in open clusters - XIV. Mean radial velocities for 1309 stars and 166 open clusters

Jean-Claude Mermilliod

Context. Radial velocities have proved to be an efficient method for membership determination if there are at least 2 or 3 red giants in a cluster. They are necessary for galactic studies, but are still missing for many open clusters. ...

Photometric membership and metallicities of red giant candidates in selected open clusters

Jean-Claude Mermilliod

As part of a long-term project to determine abundances and astrophysical properties of evolved red stars in open clusters, we present high-precision DDO photoelectric observations for a sample of 33 red giant candidates projected in the fields of nine Gala ...

The evolution of the brightest cluster galaxies since z similar to 1 from the ESO Distant Cluster Survey (EDisCS)

Pascale Jablonka, Anja Von der Linden

We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey (EDisCS). These data are combined with the photometry published by Aragon Salamanca, Baugh & Kauffmann and a low-redshift comparison sample built from the ...
