They also raise two pivotal questions: 1) How do their atmospheres compare to brown dwarfs? and 2) How did these large-separation massive planets form? Atmospheric modeling of directly imaged planets is complicated by the presence of condensate clouds; many successful models assume patchy cloud cover, a combination of two different atmospheres (e.g. cloudy and cloud-free). Heterogeneous cloud covers are common in brown dwarfs and lead to rotational photometric variability. In addition, different planet formation models proposed for large-separation exoplanets lead to different typical rotation rates. We pioneered HST and Spitzer rotational mapping of brown dwarfs and in a series of studies showed that this technique provides very important and unique constraints on the composition and structure of brown dwarf atmospheres and their cloud layers. We propose here to apply high-contrast, high-precision photometry to two prototypical directly imaged exoplanets (or planetary mass companions) and search for photometric variations. The observations will: 1) verify the prediction of patchy cloud cover and allow quantitative comparisons to cloud properties observed in brown dwarfs; and, 2) provide the first direct measurements of the rotation periods of wide-separation exoplanets, an important constraint on their formation mechanism. Furthermore, the proposed observations will demonstrate a new observing technique on two low-risk targets, opening a new window on directly imaged exoplanets. The observations aim to search for periodic photometric variations in two directly imaged exoplanets/planetary-mass companions. We expect such variations due to the rotation of the targets and their heterogeneous photospheres. Each target will be observed in six consective orbits. To allow high-contrast imaging we will use roll subtraction and obtain our data at the two different roll angles. The 1st, 3rd, and 5th orbits will be in Roll Angle A; Orbits 2, 4, 6 will be in Roll Angle B. Roll Angle B = Roll Angle A + [25-33 degrees] The lightcurves will be obtained in F160W and F125W, alternating these filters during the observations. In each orbit we will obtain images at four dithering positions (square); in each positions images with both filters will be taken. In Orbits 1 and 2 we will also obtain additional non-saturated images of the primaries (stars) in both systems; these very short images will be used to improve PSF subtraction and also allow the precise calibration of the pixels on which the companion's brightness is also measured. This is required to correct for the different sensitivities of the pixels in the four dithering positions.
