un 2 00 5 A Minor Axis Surface Brightness Profile for M
We use data from the Isaac Newton Telescope Wide Field Camera survey of M31 to determine the surface brightness profile of M31 along the south-east minor axis. We combine surface photometry and faint red giant branch star counts to trace the profile from the innermost regions out to a projected radius of 4 (≈ 55 kpc) where μV ∼ 32 mag arcsec ; this is the first time the M31 minor axis profile h...

متن کاملA Subaru/suprime-cam Survey of M31’s Spheroid along the South-east Minor Axis
We have used Suprime-Cam on the Subaru Telescope to conduct a V and I-band imaging survey of fields sampling the spheroid of the Andromeda galaxy along its south-east minor axis. Our photometric data are deep enough to resolve stars down to the red clump. Based on a large and reliable sample of red giant stars available from this deep wide-field imager, we have derived metallicity distributions...
متن کاملSurface Brightness Profiles of Three New Dwarf Spheroidal Companions to M31
CCD images of three newly discovered dwarf spheroidal companions to M31, And V, VI, and VII, are used to extract surface brightness profiles and total magnitudes. Using distance modulii provided by Armandroff et al. (1998 & 1999) and Grebel & Guhathakurta (1999), these galaxies are shown to have similar luminosities to other Local Group dwarf spheroidals; And V in particular is similar to Draco...
متن کاملA Survey for Low Surface Brightness Dwarf
By applying a digital ltering technique to 1550 deg 2 of the POSS-II in the vicinity of M31, we found two previously unidentiied very low surface brightness dwarf galaxies which we designate And V and VI. Follow-up imaging with the KPNO 4-m telescope resolved these into stars easily. The V-and I-band images of And V indicate a distance similar to that of M31, and {1.5. All evidence stro...
