Wednesday, May 16, 2012 SPACE-BORNE OBSERVATION OF SMALL BODIES I: AKARI, HERSCHEL, WISE, HST, AND GAIA 8: 30 a.m. Snow Hall

Chairs: Dominique Bockelee-Morvan Yanga Fernandez

8:30 a.m. Watanabe J. * Welcome Address

8:50 a.m. Mainzer A. * Bauer J. M. Grav T. Masiero J. Cutri R. McMillan R. S. Walker R. Wright E. L. Small Body Science with WISE/NEOWISE: An Update [#6087] NASA’s Wide-field Infrared Explorer (WISE) has detected more than 158,000 asteroids at thermal infrared wavelengths as a result of augmentations to its data processing pipeline known as NEOWISE. An update of the project’s status will be presented.

9:20 a.m. Usui F. * Kuroda D. Müller T. G. Hasegawa S. Ishiguro M. Ootsubo T. Kasuga T. AKARI/IRC Mid-Infrared Asteroid Survey [#6119] We present the results of the asteroid survey with IRC/AKARI. Based on the IRC All-Sky Survey data, 5120 asteroids with known orbital elements are inventoried as the catalog of their the size and albedo.

9:40 a.m. Hartogh P. * Lis D. C. Bockelée-Morvan D. de Val-Borro M. Biver N. Küppers M. Emprechtinger M. Bergin E. A. Crovisier J. Rengel M. Moreno R. Szutowicz S. Blake G. A. HssO-Team Ocean like Water in Jupiter-Family Comet 103P/Hartley 2 [#6172] We present the first detection of the deuterium-to-hydrogen isotopic ratio (D/H) in a Jupiter family comet (103/P Hartley 2). Different from former D/H ratios determined in Oort cloud comets it is consistent with VSMOW.

10:00 a.m. Feldman P. D. * Weaver H. A. A’Hearn M. F. Combi M. R. Dello Russo N. Ultraviolet Spectroscopy of C/2009 P1 (Garradd) with the Hubble Space Telescope [#6165] We present observations of the gas-rich comet C/2009 P1 (Garradd) made in January 2012 with two of the spectrographs on the Hubble Space Telescope. Our preliminary analysis gives an abundance of CO relative to water of ~20%.

10:10 a.m. Tanga P. Hestroffer D. * Berthier J. Cellino A. Delbò M. DellOro A. Mignard F. Muinonen K. Pauwells T. Petit J. M. Thuillot W. CU4-SSO Team Gaia Observations of Solar System Bodies [#6283] The Gaia mission will be launched in mid-2013 by the European Space Agency (ESA). Solar system science is also well covered by the mission and has been included since the early stages of its concept and development.

10:20 a.m. Coffee Break
