Cool Stars 14 - Submitted Abstract # 105 This version created on 05 October 2006 A Palomar Adaptive Optics Coronagraphic Survey of TPF-C Candidate Targets Joseph Carson, Jet Propulsion Laboratory Kyle Hiner, Jet Propulsion Laboratory Karl Stapelfeldt, Jet Propulsion Laboratory Alex Rudolph, Cal Poly Pomona We present here a status report on an ongoing Palomar Hale Telescope adaptive optics coronagraphic survey that searches for sub-stellar companions around 28 TPF-C candidate targets. Sub-stellar objects found around such targets could have important implications for space-based observing programs like TPF-C, that wish to image narrow-separation planetary objects; an existent brown dwarf companion, for instance, might degrade the sensitivity of narrow-separation space-based observations by way of its interfering light; or, the existence of an orbiting brown dwarf could affect the likelihood of a narrow-separation planetary orbit. Our survey therefore helps constrain and direct TPF-C candidate target selection, while providing scientifically important substellar companion information on the nearby stellar neighborhood. ----------------------------------
