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…
The importance of tides for the Local Group dwarf spheroidals
J. I. Read, M. I. Wilkinson, N. Wyn Evans +2
There are two main tidal effects which can act on the Local Group dwarf spheroidals (dSphs): tidal stripping and tidal shocking. Using N-body simulations, we show that tidal stripp…
Ursa Major: a missing low-mass CDM halo?
J. T. Kleyna, M. I. Wilkinson, N. W. Evans +1
The recently discovered Ursa Major dwarf spheroidal (dSph) galaxy candidate is about five to eight times less luminous than the faintest previously known dSphs And IX, Draco, and U…
Distant Field BHB Stars III: Identification of a probable outer halo stream at Galactocentric distance r = 70 kpc
L. Clewley, S. J. Warren, P. C. Hewett +3
We present VLT-FORS1 spectra of a sample of 34 faint 20.0 < g* < 21.1 A-type stars selected from the Sloan Digital Sky Survey Early Data Release, with the goal of measuring the vel…
Spectroscopic Survey of the Galaxy with Gaia II. The expected science yield from the Radial Velocity Spectrometer
M. I. Wilkinson, A. Vallenari, C. Turon +21
The Gaia mission is designed as a Galaxy explorer, and will measure simultaneously, in a survey mode, the five or six phase space parameters of all stars brighter than 20th magnitu…
The tidal stripping of satellites
J. I. Read, M. I. Wilkinson, N. W. Evans +2
We present an improved analytic calculation for the tidal radius of satellites and test our results against N-body simulations. The tidal radius in general depends upon four factor…
