SUMMARY: WE HAVE ESTABLISHED AN INTERDISCIPLINARY OBSERVING PROGRAM THAT COMBINES THEHIGH-CONTRAST IMAGING TECHNIQUE AND THE DOPPLER RADIAL VELOCITY (RV) METHOD IN ORDER TOADDRESS OUTSTANDING QUESTIONS REGARDING THE CHARACTERIZATION OF BROWN DWARFS AND EXTRASOLARPLANETS. SPECIFICALLY WE ARE USING SENSITIVE IMAGING OBSERVATIONS TO TARGET STARS THAT EXHIBITLONG-TERM RV TRENDS INDICATIVE OF A DISTANT SUBSTELLAR COMPANION. THE GOAL OF THIS WORK IS TODIRECTLY DETECT AND ACQUIRE THE SPECTRUM OF THE BODY RESPONSIBLE FOR ACCELERATING ITS HOST STAR.BY WORKING AT THE INTERFACE OF TWO POWERFUL AND COMPLEMENTARY DETECTION TECHNIQUES THISPROGRAM WILL:1. SIGNIFICANTLY IMPROVE THE EFFICIENCY OF HIGH-CONTRAST IMAGING OBSERVATIONS BY STARTINGFROM AN INTRINSICALLY RICH SAMPLE OF TARGET STARS: THOSE THAT ARE ALREADY KNOWN TO HOSTA SUBSTELLAR COMPANION;2. RESULT IN THE ACQUISITION OF DIRECT SPECTRO-PHOTOMETRIC MEASUREMENTS FOR LOW-MASSCOMPANIONS ACROSS A VERY WIDE WAVELENGTH RANGE (YJHKLM) TO TEST CURRENTTHEORETICAL ATMOSPHERIC MODELS;3. BREAK THE SIN(I) DEGENERACY INHERENT TO THE RV METHOD ALLOWING CALCULATION OF THETHREE-DIMENSIONAL ORBIT (ALL SIX ELEMENTS) OF BROWN DWARFS AND EXTRASOLAR PLANETS;4. CALCULATE BROWN DWARF AND EXTRASOLAR PLANET TRUE MASSES USING ORBITAL DYNAMICS(I.E. INDEPENDENT OF SPECTRA) TO ESTABLISH AN EXPLICIT CONNECTION BETWEEN THEIRRADIATIVE PROPERTIES AND MASS AND AGE THUS PROVIDING A MUCH-NEEDED ANCHORINGPOINT TO GUIDE THE DEVELOPMENT OF MORE ADVANCED ATMOSPHERIC MODELS.OUR TEAM COMBINES ESTABLISHED AND LEADING EXPERTS IN BOTH THE FIELDS OF HIGH-CONTRAST IMAGINGAND PRECISION VELOCIMETRY. ALL OF THE TOOLS REQUIRED TO CARRY OUT THIS PROGRAM ARE THUS ALREADY INPLACE. INDEED WE HAVE RECENTLY CONDUCTED A PILOT PROGRAM AT KECK TO DEMONSTRATE THE POWER OFTHIS APPROACH. WITH CONSISTENT ACCESS TO HIRES AND NIRC2 WE ARE WELL ON OUR WAY TOWARDSACHIEVING THESE GOALS.WE ARE REQUESTING NASA ORIGINS SUPPORT TO CONTINUE OPERATIONS AT KECK AND TO ALSOSIGNIFICANTLY ENHANCE AND EXPAND THIS PROGRAM BY CONDUCTING HIGH-CONTRAST OBSERVATIONS ATPALOMAR USING EXTREME ADAPTIVE OPTICS (AO) AND THE PROJECT 1640 SPECTRAL IMAGER. PROJECT1640 IS DESIGNED SPECIFICALLY FOR HIGH-CONTRAST IMAGING AND WILL BE TWO ORDERS OF MAGNITUDEMORE SENSITIVE THAN NIRC2 AT KECK. THE PI IS A KEY SCIENCE MEMBER OF THE PROJECT 1640 TEAM.WE HAVE BEEN AWARDED 99 NIGHTS OF GUARANTEED TIME OVER THE NEXT THREE YEARS TO SEARCH FOREXTRASOLAR PLANETS AND CHARACTERIZE THEIR ATMOSPHERES.THIS STUDY IS VERY WELL-ALIGNED WITH NASA'S 2011 STRATEGIC GOALS TO REVEAL THE DIVERSITYOF PLANETS AND PLANETARY SYSTEM ARCHITECTURES IN OUR GALAXY STUDY STELLAR AND PLANETARYENVIRONMENTS AND GENERATE A CENSUS OF EXTRASOLAR PLANETS AND MEASURE THEIR
