Abstract
We present CCD B,V and R surface photometry for a subsample of 67 blue compact galaxies (BCGs) drawn from the First and Second Byurakan surveys. We outline the range of typical photometric parameters for the investigated subsample. The surface brightness profiles were built for all BCGs. The profile decomposition was done using two-component model: an exponential disk and/or a gaussian component at small effective radii. The (B-V) and for the part of galaxies (V-R) color profiles were derived. The analysis shows the variety of morphologies, and large range of galaxy sizes and exponential disk structural parameters. We use these data to check possible correlations between various physical parameters and gain insight into star-forming processes in BCGs. We compare structural parameters for our BCGs to those of other types of dwarf galaxies – dIrr, dE and LSBD galaxies to look for possible connections between them and BCGs.
