Abstract / Description:We report the discovery of a new dwarf
spheroidal satellite of M31, Andromeda IX, based
on resolved stellar photometry from the Sloan
Digital Sky Survey (SDSS). Using both SDSS and
public archival data, we have estimated its
distance and other physical properties, and
compared these to the properties of a previously
known dwarf spheroidal companion, Andromeda V,
also observed by SDSS. Andromeda IX is the
lowest surface brightness galaxy found to date
(‚‚mu;V,0~26.8 mag
arcsec-2), and at the distance we
estimate from the position of the tip of
Andromeda IX's red giant branch,
(m-M)0~24.5 (805 kpc), Andromeda IX
would also be the faintest galaxy known
(MV~-8.3).
