Descripción
BVRI surface photometry is presented for the interacting galaxy pair Arp
86 (NGC 7753-7752). Deep high-resolution images were obtained in order
to study the faint tidal features. The bridge was found to be bluer than
the tail both in V - R and B - V, the V - R color probably suggesting
enhanced long-term star formation in the bridge. The end of the bridge
is extremely blue in B - V (0.2-0.4), thus indicating present ongoing
star formation. The CCD images were also used to estimate initial
parameters, such as inclinations and disk scale lengths for the
dynamical modeling of Arp 86, presented in Salo and Laurikainen (1993).
