Searches for HI in the Outer Parts of Four Dwarf Spheroidal Galaxies
, 1999 Previous searches for atomic gas in our Galaxy's dwarf spheroidal companions have not been complete enough to settle the question of whether or not these galaxies have HI, especially in their outer parts.

The Magellanic Group and the Seven Dwarfs [PDF]
, 2008 The Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. This group, dominated by the LMC, contained ~4% of the mass of the Milky Way prior to its accretion and tidal disruption, but ~

The mass content of the Sculptor dwarf spheroidal galaxy [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractWe present a new determination of the mass content of the Sculptor dwarf spheroidal galaxy, based on a novel approach which takes into account the two distinct stellar populations present in this galaxy. This method helps to partially break the well-known mass-anisotropy degeneracy present in the modelling of pressure-supported stellar systems.

DELVE-DEEP Survey: The Faint Satellite System of NGC 55
The Astrophysical JournalWe report the first comprehensive census of the satellite dwarf galaxies around NGC 55 (2.1 Mpc) as a part of the DECam Local Volume Exploration DEEP (DELVE-DEEP) survey. NGC 55 is one of four isolated, Magellanic analogs in the Local Volume around which

Variable Stars in Dwarf Spheroidal Galaxies [PDF]
International Astronomical Union Colloquium, 1973 Interest in dwarf spheroidal galaxies is motivated by a number of reasons; an important one on the occasion of this colloquium is the abundance of variable stars. The theory of stellar evolution and stellar pulsations is now able to predict from theoretical considerations characteristic properties of variable stars in the colour-magnitude diagram (Iben,

A SPECTROSCOPIC BINARY IN THE HERCULES DWARF SPHEROIDAL GALAXY [PDF]
The Astrophysical Journal, 2013 We present the radial velocity curve of a single-lined spectroscopic binary in the faint Hercules dwarf spheroidal (dSph) galaxy, based on 34 individual spectra covering more than two years of observations. This is the first time that orbital elements could be derived for a binary in a dSph.

Galaxias Enanas del Grupo Local
Momento, 2009 The satellite galaxies of the Milky Way are very important both for the studies of the formation and evolution of galaxies and for the research on the dark matter problem. In the present review paper some structural properties of the Local Group, as well
