Searching for accreting protoplanets with SPHERE/ZIMPOL at the VLT

In this poster I present high angular resolution observations of two transition disks with SPHERE/ZIMPOL at the VLT. We have observed the targets in both the H_alpha and Continuum filters to detect strong accreting protoplanets inside the disk gaps. I discuss the main results, including upper limits to the companion accretion rates at different separations from the central object.
