The detection of exoplanets through high contrast imaging has significant advantages over the more prolific transit and radial velocity methods due to its ability to probe the widest separations of planetary systems. However, thus far only a small number of very massive (>5 M_J) companions have been found due to the limitations of current instrumentation. The James Webb Space Telescope (JWST), currently scheduled for launch in 2021, will have high contrast imaging capabilities and will likely improve our ability to image lower mass companions. To estimate this improvement I am performing a number of JWST observational simulations on the most favourable targets in an effort to determine the limits of its capabilities. During my talk I will perform a brief introduction into JWST and high contrast imaging in addition to describing my methodology and latest results.
