Numerical simulations of the metallicity distribution in dwarf spheroidal galaxies
E. Ripamonti, E. Tolstoy, A. Helmi +2
Recent observations show that the number of stars with very low metallicities in the dwarf spheroidal satellites of the Milky Way is low, despite the low average metallicities of s…

A new view of the dwarf spheroidal satellites of the Milky Way from VLT/FLAMES: Where are the very metal poor stars?
Amina Helmi, M. J. Irwin, E. Tolstoy +13
As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby dwarf spheroidal ga…

The DART imaging and CaT survey of the Fornax Dwarf Spheroidal Galaxy
G. Battaglia, E. Tolstoy, A. Helmi +13
As part of the DART project we have used the ESO/2.2m Wide Field Imager in conjunction with the VLT/FLAMES GIRAFFE spectrograph to study the detailed properties of the resolved ste…
