The properties of dwarf spheroidals are reviewed with emphasis on the newly discovered Sextans system, as well as on the star formation histories, the dark matter content and the abundance — luminosity relation of these galaxies. The relation of dwarf spheroidals to other dwarf galaxies is also discussed.

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.

The Origin of the Diversity of Dwarf Spheroidal Galaxies
AIP Conference Proceedings, 2010We present a large sample of 166 fully self-consistent hydrodynamical N-body/Tree-SPH simulations of isolated dwarf spheroidal galaxies [1]. It has enabled us to identify the key physical parameters and mechanisms at the origin of the observed variety in the Local Group dSph properties.

Dwarf spheroidal galaxies in the M81 group of galaxies
Astronomische Nachrichten, 2009AbstractWe study the properties of the dwarf galaxy population in the nearby interacting M81 group of galaxies. In particular, we are deriving the metallicity distribution functions, the ages and the star formation histories of these dwarf galaxies based on data from the Hubble Space Telescope's Advanced Camera for Surveys and the Sloan Digital Sky ...

Planetary Nebulae in the Sagittarius Dwarf Spheroidal Galaxy
2006The Sagittarius dwarf galaxy (Sgr) is a satellite of the Galaxy, located behind the Galactic Bulge. It is the nearest extra-galactic system, at a distance of 25 kpc. Sgr contains three known planetary nebulae (PNe) (two from Zijlstra & Walsh 1996, and one new identification).
