Inhomogeneous chemical evolution of dwarf spheroidal galaxies
Astrophysics and Space Science, 2003Stellar abundance pattern of n-capture elements such as barium is used as a powerful tool to infer how the star formation proceeded in dwarf spheroidal (dSph) galaxies. It is found that the abundance correlation of barium with iron in stars belonging to dSph galaxies orbiting the Milky Way, i.e., Draco, Sextans, and Ursa Minor have a feature similar to

Dwarf Spheroidal Galaxies: Dynamical Evolution
Astrophysics and Space Science, 1998We show the results of numerical simulations of dwarf spheroidal galaxies (DSphs), which allow to understand their evolution in the framework of no internal virial equilibrium. Under this hypothesis, we reproduce with a low dark matter (DM) model the high values of the virial M/L ratio measured observationally for these objects.

Searches for dwarf spheroidal galaxies
Astrophysics, 19751. Dwarf spheroidal galaxies are encountered, it would seem, more often than previously assumed [9]. 2. The tendency for them to be concentrated around galaxies of high luminosities [8, 9] is not very pronounced. 3. The distribution of Sculptor type dwarfs in the space we studied is not uniform.
