Abstract:
At a redshift of 0.18, Abell 1689 is so far the most distant cluster
of galaxies for which substantial mid-infrared (MIR) data have been
published. Its mapping with the ISOCAM camera onboard the ISO
satellite allowed the detection of 30 cluster members at 6.75µm
(LW2 filter) and 16 cluster members at 15µm (LW3 filter) within a
clustercentric radius of 0.5Mpc (Fadda et al., 2000A&A...361..827F 2000A&A...361..827F,
Paper I). We present here the follow-up optical photometric and
spectroscopic observations which were used to study the individual
properties of the galaxy members of A1689. We confirm the high
fraction of blue galaxies initially reported in this rich cluster by
Butcher & Oemler (1984ApJ...285..426B 1984ApJ...285..426B), that was challenged by some
subsequent studies. We discuss the spectral and morphological
properties of all cluster members in our spectroscopic sample, and of
the MIR-detected galaxies in particular.
