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 ...

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.

On the Formation of Dwarf Spheroidal Galaxies
Publications of the Astronomical Society of Japan, 1979Abstract In order to explain why the mass density of dwarf spheroidal galaxies is so low, the following hypothesis is proposed: dwarf spheroidals were born as dense systems but afterward they have expanded due to the supernova-driven gas ejection.

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.

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

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).

A formation scenario of dwarf spheroidal galaxies
Astrophysics and Space Science, 2008In this paper, the author proposes a formation scenario of dwarf spheroidal galaxies (dSphs); part of dSphs form as a result of collision of dark matter (DM) halos which retain ISM (interstellar medium). First of all, a primordial dSph forms compact when collision of DM halos occurs.

On Dark Matter in Dwarf Spheroidal Galaxies
EAS Publications Series, 2011The small (L V ≤ 107 L V ,⊙ ) baryonic components of the Milky Way’s dwarf spheroidal (dSph) satellites contribute small “backgrounds” with regards to estimates of dSph dark matter density profiles and any related predictions of dark matter decay/annihilation signals. As dSphs gain attention from a broad range of physicists interested in dark matter,
