Friday, March 22, 2013 [F551] REMOTE SENSING OF SMALL BODIES 1:30 p.m. Waterway Ballroom 1

Chairs: Faith Vilas Tasha Dunn

1:30 p.m. Dunn T. L. * Burbine T. H. Bottke W. F. Clark J. P. Mineralogies and Source Regions of Near Earth [#1197] We determine the mineralogies and source regions of 72 near-Earth asteroids, most of which are S-types or Q-types.

1:45 p.m. Murchie S. L. * Fraeman A. A. Arvidson R. E. Rivkin A. S. Morris R. V. Internal Characteristics of Phobos and Deimos from Spectral Properties and Density: Relationship to Land-Forms and Comparison with Asteroids [#1604] Phobos, Deimos, and other small bodies show a relationship between estimated macroporosity in the interior and the types of landforms present on the surface.

2:00 p.m. Fraeman A. A. * Murchie S. L. Arvidson R. E. Rivkin A. S. Morris R. V. Constraints on the Compositions of Phobos and Deimos from Mineral Mapping [#1572] Results from mapping mineral absorptions on Phobos and Deimos using visible/near infrared CRISM observations. Discovery and implications of feature at 0.65 µm.

2:15 p.m. Capaccioni F. * Filacchione G. De Sanctis M. C. Capria M. T. Tosi F. et al. Photometric Properties of the 21 Lutetia from VIRTIS-Rosetta Observations [#2229] This work describes photometric corrections applied to the VIRTIS-Rosetta spectra of the asteroid Lutetia and the resulting surface color variation identified.

2:30 p.m. Conrad A. R. * Merline W. J. La Camera A. Boccacci P. Bertero M. et al. Detecting Asteroid Satellites with LINC-NIRVANA at the Large Binocular Telescope [#2032] Asteroid satellites help determine , density, and composition. LINC-NIRVANA will yield a factor of 3 improvement in the limiting separation for detections.

2:45 p.m. Sugita S. * Kuroda D. Kameda S. Hasegawa S. Kamata S. et al. Visible Spectroscopic Observations of Asteroid 162173 (1999 JU3) with the Gemini-S Telescope [#2591] Our results suggest that the surface of 1999JU3 may be covered with partially devolatilized CM-like materials and that its parent body could be 163 Erigone.

3:00 p.m. Shepard M. K. * Nolan M. C. Springmann A. Howell E. S. Taylor P. A. et al. Radar Observations of Three X/M-Class Main-Belt Asteroids [#2408] We present observations of 3 M-class asteroids: 110 Lydia, 359 Georgia, and 779 Nina. All show evidence of high metal content. Two have bifurcated radar echoes.

3:15 p.m. Wlodarczyk I. Leliwa-Kopystynski J. * Cumulative Distributions of Asteroids in the Families [#1879] Families are extracted from 292003 asteroids. Size distributions in the different ranges of sizes and catastrophic vs. cratering forming-event are considered.

3:30 p.m. Walsh K. J. * Delbo M. Bottke W. F. Vokrouhlicky D. Lauretta D. S. Introducing the Eulalia and New Polana Families: Re-Assesing Primitive Asteroid Families in the Inner Main-Belt [#2835] Two primitive asteroid families dominate the inner main and are therefore a dominate source of primitive NEOs.

3:45 p.m. Cikota S. * Ortiz J. L. Morales N. Moreno F. Tancredi G. A Photometric Search for Main Belt [#1520] A photometric search for main belt comets just by using the MPCAT-OBS Observation Archive.

4:00 p.m. Waszczak A. * Ofek E. O. Aharonson O. Kulkarni S. R. Bauer J. et al. A Search for Main-Belt Comets as Extended Objects in the Palomar Transient Factory Survey [#2008] We search the Palomar Transient Factory (PTF) wide-field survey to refine the statistical upper limits on the population size of main-belt comets.

4:15 p.m. Vincent J.-B. * Sierks H. Rose M. Jet Activity on the Cliffs of 9P/Tempel 1 [#2401] Cliff of Tempel 1 / Source of gas and dust jets / Modeled with COSSIM.

4:30 p.m. Vilas F. * Reflectance Spectrophotometry of the Irregular Outer Jovian Satellites as Insight to Solar System History [#2900] Reflectance spectra of JVI Himalia, JVII Elara, JVIII Pasiphae, JIX Sinope, JX Lysithea, JXI Carme, and JXII Ananke address solar system formation conditions.
