Correlation of structure and stellar properties of galaxies in Stripe 82
  Establishing a correlation (or lack thereof) between the bimodal colour
distribution of galaxies and their structural parameters is crucial to
understand the origin of bimodality. To achieve that, we have performed 2D
mass-based structural decomposition (bulge+disc) of all disc galaxies
(total$=$1263) in the Herschel imaging area of the Stripe 82 region using $K_s$
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 disc galaxies.
The rest of the galaxies ($<20\%$) are marked as discs with "ambiguous" bulges.
Pseudo and classical bulge disc galaxies exhibit clear bimodality in terms of
all stellar parameters ($M_*$, sSFR, $r-K_s$). All pseudo bulge disc galaxies
are blue and star-forming and all classical bulge disc galaxies are red and
quiescent with less than $5\%$ digressions. Ambiguous bulge disc galaxies are
intermittent to pseudo and classical bulge disc galaxies in the distribution of
all structural and stellar parameters. $\Delta$$\langle\mu_{eb}\rangle$ - 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 disc galaxies on scaling relations and
fundamental plane, in addition to their peculiar stellar properties suggest
that they are dominantly a part of the green valley.
