Keck/NIRC2 L'-band Imaging of Jovian-mass Accreting Protoplanets around PDS 70

We present L'-band imaging of the PDS 70 planetary system with Keck/NIRC2 using the new infrared pyramid wave front sensor. We detected both PDS 70 b and c in our images, as well as the front rim of the circumstellar disk. After subtracting off a model of the disk, we measured the astrometry an...
