We have recently detected a wide separation planetary-mass companion to a member of the 22 Myr β Pic moving group. Furthermore, we have also confirmed a free-floating planetary-mass object as a member of the β Pic moving group. These two objects share their mass and age with the directly-imaged planet β Pic b, and represent the only known objects to share their mass and age with a close-in, directly imaged planet. We propose to obtain near-IR photometric variability monitoring observations our newly discovered companion and free-floating planetary-mass object. These observations will allow us to investigate the presence of inhomogeneities in their atmospheres and also provide a measurement of the rotational period of the new planetary-mass companion. Additionally, we propose to measure the radial velocity of the primary with Gemini/GNIRS at two epochs. This will allow us to explore the possibility that the unresolved binarity of the system may have influenced the initial RV measurement.
