Complexity on Small Scales III: Iron and alpha Element Abundances in the Carina Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, G. F. Gilmore +5
We have obtained high-resolution spectroscopy of ten red giants in the Carina dwarf spheroidal (dSph) with UVES at the ESO/VLT. Here we present the abundances of O,Na,Mg,Si,Ca,Ti a…
Star-formation in the HI bridge between M81 and M82
Duilia F. de Mello, L. J. Smith, E. Sabbi +3
We present multi-wavelength observations of stellar features in the HI tidal bridge connecting M81 and M82 in the region called Arp's Loop. We identify eight young star-forming reg…
Stellar kinematics in the remote Leo II dwarf spheroidal galaxy -- Another brick in the wall
A. Koch, J. T. Kleyna, M. I. Wilkinson +5
We present the projected velocity dispersion profile for the remote (d=233kpc) Galactic dwarf spheroidal (dSph) galaxy Leo II, based on 171 discrete stellar radial velocities that…
Complexity on Small Scales II: Metallicities and Ages in the Leo II Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, J. T. Kleyna +5
We present metallicities and ages for 52 red giants in the remote Galactic dwarf spheroidal (dSph) galaxy Leo II. These stars cover the entire surface area of Leo II and are radial…
The Age-Metallicity Relation of the SMC
A. Kayser, E. K. Grebel, D. R. Harbeck +4
The Small Magellanic Cloud (SMC) is the only dwarf galaxy in the Local Group known to have formed and preserved populous star clusters continuously over the past 12 Gyr. These clus…
Complexity on Small Scales: The Metallicity Distribution of the Carina Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, R. F. G. Wyse +5
The Carina dwarf spheroidal (dSph) galaxy is the only galaxy of this type that shows clearly episodic star formation separated by long pauses. Here we present metallicities for 437…
