| Description | A
Shell galaxy is an elliptical
galaxy that is surrounded by
faint arcs or shells of stars,
often more blue than the galaxy
as a whole. Shell systems have a
variety of morphologies; some
galaxies have shells transverse
to the major axis and
interleaved on opposite sides of
the centre of the galaxy, while
other galaxies have shells
distributed at all position
angles. The fraction of field
ellipticals with shell-like
features is at least 17% and may
be as much as 44%. They may be
the result of galactic
cannibalism. NGC 1210 in
Fornax is a good example.
The total magnitude is 13.5 and
the size is 2.0' x 1.7'. |
