M32: Is There An Ancient, Metal-Poor Population?

G. Fiorentino, A. Monachesi, S. Trager +7

We observed two fields near M32 with the ACS/HRC on board the Hubble Space Telescope, located at distances of about 1.8' and 5.4' (hereafter F1 and F2, respectively) from the cente…

The Dynamical and Chemical Evolution of Dwarf Spheroidal Galaxies

Y. Revaz, P. Jablonka, T. Sawala +8

We present a large sample of fully self-consistent hydrodynamical Nbody/Tree-SPH simulations of isolated dwarf spheroidal galaxies (dSphs). It has enabled us to identify the key ph…

Chemical Composition of Extremely Metal-Poor Stars in the Sextans Dwarf Spheroidal Galaxy

W. Aoki, N. Arimoto, K. Sadakane +15

Chemical abundances of six extremely metal-poor ([Fe/H]<-2.5) stars in the Sextans dwarf spheroidal galaxy are determined based on high resolution spectroscopy (R=40,000) with the…

Stellar Metallicities and Kinematics in a Gas-Rich Dwarf Galaxy: First Calcium Triplet Spectroscopy of RGB Stars in WLM

Ryan Leaman, Andrew A. Cole, Kim A. Venn +5

We present the first determination of the radial velocities and metallicities of 78 red giant stars in the isolated dwarf irregular galaxy WLM. Observations of the calcium II tripl…

Blue straggler stars in dwarf spheroidal galaxies II: Sculptor and Fornax

M. Mapelli, E. Ripamonti, G. Battaglia +4

The existence of blue straggler stars (BSSs) in dwarf spheroidal galaxies (dSphs) is still an open question. In fact, many BSS candidates have been observed in the Local Group dSph…
