  We present high resolution Karl G. Jansky Very Large Array (VLA) observations
of the protostar L1527 IRS at 7 mm, 1.3 cm, and 2 cm wavelengths. We detect the
edge-on dust disk at all three wavelengths and find that it is asymmetric, with
the southern side of the disk brighter than the northern side. We confirm this
asymmetry through analytic modeling and also find that the disk is flared at 7
mm. We test the data against models including gap features in the intensity
profile, and though we cannot rule such models out, they do not provide a
statistically significant improvement in the quality of fit to the data. From
these fits, we can however place constraints on allowed properties of any gaps
that could be present in the true, underlying intensity profile. The physical
nature of the asymmetry is difficult to associate with physical features due to
the edge-on nature of the disk, but could be related to spiral arms or
asymmetries seen in other imaging of more face-on disks.
