We utilize for the first time HST ACS imaging to examine the structuralproperties of galaxies in the rest-frame U-V versus V-J diagram (i.e., the UVJdiagram) using a sample at 0.6<z<0.9 that reaches a low stellar mass limit (logM/Msun>10.25). The use of the UVJ diagram as a tool to distinguish quiescentgalaxies from star forming galaxies (SFGs) is becoming more common due to itsability to separate red quiescent galaxies from reddened SFGs. Quiescentgalaxies occupy a small and distinct region of UVJ color space and we find mostof them to have concentrated profiles with high Sersic indices (n>2.5) andsmooth structure characteristic of early-type systems. SFGs populate a broad,but well-defined sequence of UVJ colors and are comprised of objects with a mixof Sersic indices. Interestingly, most UVJ-selected SFGs with high Sersicindices also display structure due to dust and star formation typical of then<2.5 SFGs and late-type systems. Finally, we find that the position of a SFGon the sequence of UVJ colors is determined to a large degree by the mass ofthe galaxy and its inclination. Systems that are closer to edge-on generallydisplay redder colors and lower [OII]3727 luminosity per unit mass as aconsequence of the reddening due to dust within the disks. We conclude that thetwo main features seen in UVJ color space correspond closely to the traditionalmorphological classes of early and late-type galaxies.
