J/ApJ/658/960 SB profiles of 9 late-type disk galaxies (Carollo+, 2007) ================================================================================ Old and young bulges in late-type disk galaxies. Carollo C.M., Scarlata C., Stiavelli M., Wyse R.F.G., Mayer L. =2007ApJ...658..960C ================================================================================ ADC_Keywords: Galaxies, photometry Keywords: galaxies: bulges - galaxies: evolution - galaxies: formation - galaxies: spiral - galaxies: stellar content Abstract: We use HST ACS and NICMOS imaging to study the inner B-I and I-H colors of nine late-type spiral galaxies, which we interpret on the basis of different star formation histories. The colors and scale lengths of the bulges of these late-type systems are correlated with those of the disks in which they are embedded. We find that in about half of the systems, the bulk of the bulge mass formed more recently than the disk. In the remainder, early bulge formation was supplemented by continuing "rejuvenating" star formation. More massive bulges are generally older. Description: The nine galaxies of the present sample were selected from our WFPC2 and NICMOS survey.
