  ASTEROIDAL BODIES AND THE BUILDING BLOCKS OF THE PLANETS WERE SHAPED IN THE FIRST ~100 MYR OF OUR SOLAR SYSTEM S HISTORY BY THE HEATING PRODUCED BY THE DECAY OF SHORT-LIVED RADIONUCLIDES AND BY IMPACTS AND COLLISIONS WITH OTHER BODIES. EVIDENCE FOR THIS PROCESSING IS SEEN IN METEORITES TODAY, AND HAS BEEN USED TO CONSTRAIN THE PROCESSES AT WORK DURING THE FORMATION OF OUR SOLAR SYSTEM. HOWEVER, TO DATE, THESE PROCESSES HAVE LARGELY BEEN STUDIED INDEPENDENTLY OF ONE ANOTHER. WE PROPOSE TO STUDY AND QUANTIFY THE ROLES THAT THESE PROCESSES HAD IN SHAPING THE PROPERTIES OF PRIMITIVE BODIES. THE RESULTS OF OUR STUDY WILL BE COMPARED TO THE EVIDENCE OF SHOCK PROCESSING, THERMAL EVOLUTION, AND VAPORIZATION AND CONDENSATION SEEN IN CHONDRITIC METEORITES AND OTHER PRIMITIVE BODIES. IN THIS WAY, WE WILL CONTINUE TO DEVELOP A MORE COMPLETE PICTURE OF HOW THE PROPERTIES OF PLANETARY BUILDING BLOCKS WERE DETERMINED. OUR WORK WILL PRIMARILY FOCUS ON DEVELOPING AND APPLYING THE ISALE AND ISALE3D HYDROCODES TO STUDY THE DYNAMICAL AND THERMAL EFFECTS OF PLANETESIMAL COLLISIONS, AND COUPLING THOSE RESULTS FOR 2D AND 3D THERMAL MODELS FOR THE EVOLUTION OF PLANETESIMALS. FURTHER, WE WILL EXTEND OUR PREVIOUSLY DEVELOPED MONTE CARLO MODEL FOR DETERMINING THE IMPACT HISTORY OF PLANETESIMALS, BY INCORPORATING REALISTIC COLLISION PARAMTERS (PROBABILITIES, VELOCITY DISTRIBUTIONS, IMPACTOR SIZE DISTRIBUTIONS) FROM STATE-OF-THE-ART PLANETARY ACCRETION MODELS. IN ALL CASES, THE RESULTS OF THE MODELS WILL BE COMPARED TO AND APPLIED TO UNDERSTANDING THE METEORITIC RECORD THROUGH CONSULTATION WITH COLLABORATORS AND COLLEAGUES. THIS WORK WILL HELP TO UNDERSTAND HOW GEOPHYSICAL PROCESSES SHAPED SMALLER SOLAR SYSTEM BODIES DURING THEIR EARLY EVOLUTION. SPECIFICALLY, THIS WORK WILL BE THE FIRST TO QUANTIFY, IN DETAIL, THE COMBINED EFFECTS OF COLLISIONAL PROCESSING AND RADIOGENIC HEATING IN SOLAR SYSTEM MATERIALS, AND THUS WILL PROVIDE CRITICAL INFORMATION IN INTERPRETING THE METEORITIC RECORD OF THE FIRST 100 MYR OF OUR SOLAR SYSTEM'S EVOLUTION.

  WE PROPOSE TO OBSERVE 14 INTERMEDIATE REDSHIFT MASSIVE CLUSTERS OF GALAXIES DISCOVERED VIA THE SUNYAEV- ZEL DOVICH (SZ) EFFECT BY THE SOUTH POLE TELESCOPE (SPT). CURRENTLY THE SPT SURVEY HAS MEASURED REDSHIFTS FOR 194 CLUSTERS, THE MAJORITY OF WHICH ARE NEWLY DISCOVERED CLUSTERS AT Z>0.5. WE PROPOSE TO OBSERVE A SUB-SAMPLE OF SPT CLUSTERS AT REDSHIFTS BETWEEN 0.3

  THE ISOTOPIC, CHEMICAL AND PETROLOGIC PROPERTIES OF METEORITES AND THEIR COMPONENTS WILL BE STUDIED TO PLACE CONSTRAINTS ON THE CHRONOLOGY AND PHYSICAL CONDITIONS OF HIGH TEMPERATURE EVENTS IN STELLAR ATMOSPHERES, IN THE SOLAR NEBULA, AND IN PLANETARY BODIES. EXPERIMENTS ON SYNTHETIC COMPOSITIONS WILL BE DONE IN ORDER TO BETTER UNDERSTAND CHEMICAL AND ISOTOPIC FRACTIONATION PROCESSES THAT OCCURRED IN THE SOLAR NEBULA AND REVEAL THEMSELVES IN REFRACTORY INCLUSIONS AND CHONDRULES. LASER RESONANT IONIZATION MASS SPECTROMETRY WILL BE USED TO MEASURE THE ISOTOPIC COMPOSITIONS OF TRACE ELEMENTS IN SINGLE CIRCUMSTELLAR PRESOLAR GRAINS FROM METEORITES AND TO STUDY THE ABUNDANCES 10BE, 92NB AND 182HF IN THE EARLY SOLAR SYSTEM. WE WILL ALSO COLLABORATE WITH NUCLEAR ASTROPHYSICISTS TO USE PRESOLAR GRAIN ISOTOPIC COMPOSITIONS TO CONSTRAIN STELLAR NUCLEOSYNTHESIS MECHANISMS. THE PRESOLAR AND SOLAR SYSTEM ASPECTS OF THIS STUDY ARE BROUGHT TOGETHER IN AN EFFORT TO EXAMINE THE RELATIONSHIP BETWEEN PRESOLAR GRAIN ISOTOPIC SIGNATURES AND ISOTOPIC ANOMALIES IN REFRACTORY INCLUSIONS, WHICH ARE SOLAR SYSTEM OBJECTS. THIS WORK TAKES ADVANTAGE OF HIGH PRECISION ISOTOPIC ANALYSIS BY MULTICOLLECTOR ICP MASS SPECTROMETRY. WE ARE PARTICIPATING IN A CONSORTIUM TO SEARCH FOR AND STUDY SO-CALLED "FUN" REFRACTORY INCLUSIONS, WHICH HAVE MUCH LARGER ISOTOPIC ANOMALIES THAN TYPICAL REFRACTORY INCLUSIONS. STUDY OF THE CHRONOLOGY OF THESE OBJECTS COUPLED WITH MEASUREMENT OF NEW ISOTOPIC SYSTEMS WILL REVEAL MUCH ABOUT MIXING PROCESSES IN THE SOLAR NEBULA. THE PROPOSED WORK WILL FURTHER THE GOALS OF THE NASA COSMOCHEMISTRY PROGRAM BY INCREASING THE UNDERSTANDING OF THE CHEMICAL ORIGIN OF THE SOLAR SYSTEM AND THE PROCESSES BY WHICH ITS PLANETS AND SMALL BODIES HAVE EVOLVED TO THEIR PRESENT STATES.

  THIS PROPOSAL IS RELEVANT TO GOALS STATED IN NASA S STRATEGIC PLANS AND SCIENCE ROADMAPS, SUCH AS (SMD 2010 SCIENCE PLAN) "WHAT IS THE INVENTORY OF SOLAR SYSTEM OBJECTS AND WHAT PROCESSES ARE ACTIVE IN AND AMONG THEM?", AND "HOW DID THE SUN S FAMILY OF PLANETS, SATELLITES, AND MINOR BODIES ORIGINATE AND EVOLVE?". THE PROPOSAL IS ALSO RELEVANT TO THE FOLLOWING GOAL STATED IN THE THE ASTROPHYSICS PROGRAM (SMD 2010 SCIENCE PLAN): "HOW DID THE UNIVERSE ORIGINATE AND EVOLVE TO PRODUCE THE GALAXIES, STARS, AND PLANETS WE SEE TODAY?". IN THIS WORK I PROPOSE TO MEASURE TRANSITION ELEMENT ISOTOPIC ABUNDANCES IN PRESOLAR SIC GRAINS, ESPECIALLY CHROMIUM, IRON, AND NICKEL. PRESOLAR GRAINS ARE CONDENSATES FROM STELLAR EJECTA AND THEREFORE REPRESENT THE ONLY SAMPLES CURRENTLY AVAILABLE FOR LABORATORY MEASUREMENTS OF GALACTIC CHEMICAL EVOLUTION AND STELLAR NUCLEOSYNTHESIS. THIS STUDY WILL MAINLY FOCUS ON MAINSTREAM SIC GRAINS, HOWEVER IT IS LIKELY THAT SOME OTHER GRAINS WILL BE MEASURED AS WELL. WHILE X-GRAINS WERE MOST LIKELY FORMED IN TYPE II SUPERNOVA, MAINSTREAM GRAINS CARRY THE NUCLEOSYNTHETIC RECORD OF ASYMPTOTIC GIANT BRANCH (AGB) STARS. THOSE STARS FORM ELEMENTS HEAVIER THAN THE TRANSITION ELEMENTS IN THE SLOW NEUTRON CAPTURE PROCESS (S-PROCESS). TRANSITION ELEMENTS ARE IMPORTANT SEEDS FOR THIS PROCESS. WHILE THE ABUNDANCE OF SOME ISOTOPES, E.G., 58FE, CHANGE SIGNIFICANTLY DURING THE S-PROCESS, OTHERS ARE ALMOST NOT INFLUENCED AT ALL. HENCE, THE PROCESSED ISOTOPES SHOW A CLEAR NUCLEOSYNTHETIC FINGERPRINT OF THE AGB STAR, THE UNPROCESSED ONES REPRESENT THE CHEMICAL STATE OF THE GALAXY AT THE TIME THE GRAINS PARENT STAR FORMED. FOR X-GRAINS, THE ISOTOPIC COMPOSITION MAINLY REPRESENTS A SAMPLE OF THE SUPERNOVA. OTHER STUDIES IMPLIED THAT DIFFERENT MATERIAL FROM THE SUPERNOVA NEEDS TO BE MIXED IN ORDER TO EXPLAIN THE MEASUREMENTS. THIS MIXING PROCESS IS NOT WELL UNDERSTOOD. TO MEASURE ALL ISOTOPES OF THE TRANSITION ELEMENTS WE ARE USING RESONANCE IONIZATION MASS SPECTROMETRY. AFTER SECONDARY IONS ARE EJECTED, TUNABLE TI:SAPPHIRE LASERS RESONANTLY IONIZE THE NEUTRAL PARTICLES. THIS PROCESS IS SELECTIVE SUCH THAT ONLY THE ELEMENT OF INTEREST IS IONIZED, HENCE ISOBARIC INTERFERENCE CAN BE AVOIDED. AFTER IONIZATION THE PARTICLES ARE ANALYZED IN A TIME-OF-FLIGHT MASS SPECTROMETER. A RECENT PRELIMINARY STUDY (TRAPPITSCH ET AL., 2012) SHOWED IRON ISOTOPE MEASUREMENTS IN TWELVE UNCLASSIFIED PRESOLAR SIC GRAINS. WE DID NOT FIND THE EXPECTED ANOMALIES IN 58FE DUE TO AGB NUCLEOSYNTHESIS, HOWEVER, THE DATA FIT WELL TO GALACTIC CHEMICAL EVOLUTION MODELS. HOWEVER, SOLAR SYSTEM CONTAMINATION COULD CAUSE THE LACK OF ANOMALIES. MEASURING MORE THAN ONE ELEMENT FOR ITS ISOTOPIC COMPOSITION WILL ALLOW TO CLEARLY DISTINGUISH BETWEEN THE AGB NUCLEOSYNTHESIS AND GALACTIC CHEMICAL EVOLUTION. FOR X-GRAINS, MEASURING SEVERAL ELEMENTS FOR THEIR ISOTOPIC COMPOSITION HELPS TO FURTHER UNDERSTAND THE AMBIGUOUS MIXING PROCESS. IN CONCLUSION, MEASURING ISOTOPIC ABUNDANCES IN INDIVIDUAL PRESOLAR GRAINS FOR TRANSITION ELEMENTS WILL ALLOW TO ELUCIDATE GALACTIC CHEMICAL EVOLUTION AND THE NUCLEOSYNTHETIC SIGNATURES THAT THE PRESOLAR SIC GRAINS ARE CARRYING.
