Star Formation in the Interacting Pair NGC7733/34

Abstract

The problem of star formation within the interacting pair NGC7733/34 has been studied, based on the UBVRI photometry of the source. The distribution of the colors of selected regions within the galaxies is used to infer an estimate for the age distribution of the star forming regions. The results seem to indicate the presence of numerous extended young star-forming regions in the disk of one of the two galaxies, NGC 7733, with ages in the range of $10^6$--$10^8$ yr. However, there exist no evidence for any violent star formation activity, in the past $10^8$ yr, in the nuclei of the two galaxies. The pair seems to be a merger bound system with the brightest, youngest, site of star forming activity lying at the disk interface.
