Large scale star formation in galaxies. II. The spirals NGC 3377A, NGC 3507 and NGC 4394

The identification of young star groupings (YSG) in the three spiral galaxies NGC 3377A, NGC 3507, NGC 4394 is obtained by mean of the statistical method described in Paper I. We find 83, 90, 185 YSGs, respectively. An identification map of YSGs, as well as their size distribution, their B-luminosity function, their surface luminosity density radial behaviour, are presented and comparatively discussed. These data, in addition to those in Paper I, constitute a first sample suitable for seeking correlations among properties of galaxies and their YSG, which we briefly discuss here.

Application of an objective method for the identification of Young Star Groupings in spiral galaxies

We present some results of the application of our automatic technique for the identification of Young Star Groupings (YSGs) in spiral galaxies. In this report we discuss our new results for NGC 3377a and NGC 3507 together with previously published data of NGC 7217, NGC 1058 and UGC 12732. The aim of this ongoing research is to obtain a wide sample of homogeneous data for the study of the YSGs and their relationships with the properties of their parent galaxies, using only objective identifications.
