cds-question@unistra.frgalaxiesstar-forming-regionsinfrared-photometryEstablishing a correlation (or lack thereof) between the bimodal color distribution of galaxies and their structural parameters is crucial to understand the origin of bimodality. To achieve that, we have performed a 2D mass-based structural decomposition (bulge+disk) of all disk galaxies (total=1263) in the Herschel imaging area of the Stripe 82 region using Ks-band images from the VICS82 survey. The scaling relations thus derived are found to reflect the internal kinematics and are employed in combination to select an indubitable set of classical- and pseudo-bulge-hosting disk galaxies. The rest of the galaxies (<20%) are marked as disks with "ambiguous" bulges. Pseudo- and classical bulge-disk galaxies exhibit clear bimodality in terms of all stellar parameters (M*, specific star formation rate, r-Ks). All pseudo- bulge-disk galaxies are blue and star forming, and all classical bulge-disk galaxies are red and quiescent with less than 5% digressions. Ambiguous bulge- disk galaxies are intermediate to pseudo- and classical bulge-disk galaxies in the distribution of all structural and stellar parameters. {Delta}<{mu}_eb_>-based on the placement of bulges on the Kormendy relation-is found to be the most efficient single structural indicator of both bulge type and stellar activity. The placement of ambiguous bulge-disk galaxies on scaling relations and the fundamental plane, in addition to their peculiar stellar properties, suggests that they are dominantly part of the green valley.2020ApJ...899...89Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/899/89CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/218 : ELODIE archive (Prugniel+, 2001)J/MNRAS/276/1341 : Spectroscopy of E and S0 galaxies (Jorgensen+, 1995)J/ApJS/147/1 : Classification of nearby galaxies (Conselice+, 2003)J/AJ/128/163 : Galaxy morphological classification (Lotz+, 2004)J/ApJ/644/30 : HST Observations of 2 high-z clusters (Blakeslee+, 2006)J/AJ/136/773 : Structure of classical bulges & pseudobulges (Fisher+, 2008)J/MNRAS/393/1531 : BUDDA structural properties of galaxies (Gadotti+, 2009)J/AJ/142/3 : 1.4GHz observations of Stripe 82 (Hodge+, 2011)J/ApJS/196/11 : Bulge+disk decompositions of SDSS galaxies (Simard+, 2011)J/MNRAS/435/1186 : BI photometry of bulgeless galaxies (Sachdeva, 2013)J/ApJ/794/120 : Sloan Digital Sky Survey coadd.
