We present ALMA 0.87 mm continuum , HCO + J=4–3 emission line , and CO J=3–2 emission line data of the disk of material around the young , Sun-like star PDS 70 .
These data reveal the existence of a possible two component transitional disk system with a radial dust gap of 0 \farcs 42 \pm 0 \farcs 05 , an azimuthal gap in the HCO + J=4–3 moment zero map , as well as two bridge-like features in the gas data .
Interestingly these features in the gas disk have no analogue in the dust disk making them of particular interest .
We modeled the dust disk using the Monte Carlo radiative transfer code HOCHUNK3D \citep whitney13 using a two disk components .
We find that there is a radial gap that extends from 15-60 au in all grain sizes which differs from previous work .
