Description
CCD surface photometry of the radio galaxy B2 0034+25 is reported.
Fourier analysis of the intensity variations along a set of closely
spaced elliptical contours fitted to the intensity distribution reveals
a high positive cos 4-theta component in the inner 10 arcsecs.
Subtraction of elliptical models of the stellar light shows the presence
of a disk component at approximately a right angle to the axis of the
radio jet. The warped structure of the disk suggests that it is settling
into a preferred orientation along the major axis of the main galaxy.
The morphology of the system as the result of a merging process and the
role of the stellar disk in the collimation of the radio plasma are
discussed.
