| Abstract | Directly imaging Earth-sized exoplanets from the ground poses a considerable challenge for adaptive optics systems. For this endeavor, natural and laser guide stars are either too dim, or are outside of the science band. To overcome these limitations, a satellite carrying a bright light source could be placed into orbit to act as a guide beacon and photometric calibrator. Tomographic reconstruction of the atmosphere could be enabled using a small constellation of beacons flying in formation around the target. Eccentric orbits are found that would keep guide beacons near their target for one to three hours every 3-10 nights. These orbital parameters, the brightness of the beacons, and other considerations for high contrast imaging are discussed. |
