Query: Near-IR Polarized Scattered Light Imagery of the DoAr 28 Transitional
  Disk   We present the first spatially resolved polarized scattered light H-band
detection of the DoAr 28 transitional disk. Our two epochs of imagery detect
the scattered light disk from our effective inner working angle of 0.10" (13
AU) out to 0.50" (65 AU). This inner working angle is interior to the location
of the system's gap inferred by previous studies using SED modeling (15 AU). We
detected a candidate point source companion 1.08" northwest of the system;
however, our second epoch of imagery strongly suggests that this object is a
background star. We constructed a grid of Monte Carlo Radiative Transfer models
of the system, and our best fit models utilize a modestly inclined (50 deg),
0.01 Msun disk that has a partially depleted inner gap from the dust
sublimation radius out to ~8 AU. Subtracting this best fit, axi-symmetric model
from our polarized intensity data reveals evidence for two small asymmetries in
the disk, which could be attributable to variety of mechanisms.
