Della Corte V. Rotundi A. Accolla M. Ferrari M. Ivanovski S. et al. POSTER LOCATION #370 GIADA (Grain Impact Analyser and Accumulator): Activity Performed in Support to the 67P/Churyumov-Gerasimenko Encounter [#2620] The Rosetta S/C on the January 20, 2014, will exit from the hibernation phase. Results on GIADA activities performed for the 67P/C-G encounter are reported.

Liao Y. Su C. C. Finklenburg S. Rubin M. Ip W.-H. et al. POSTER LOCATION #371 3-D DSMC Simulations of Comet 67P/Churyumov-Gerasimenko [#1764] Simulation of gas outflow from the Rosetta target comet has been performed using a 3-D code in preparation for the prime mission, which starts this year.

Rubin M. Fougere N. Altwegg K. Combi M. R. Le Roy L. et al. POSTER LOCATION #372 Gas and Dust Redeposition on the Surface of Comet 67P/Churyumov-Gerasimenko [#1860] We investigate the redeposition of gas and dust back to Comet 67P’s surface and show how this increases the activity during the outbound part of the orbit.

Lisse C. M. Christian D. J. Wolk S. J. Dennerl K. Combi M. R. et al. POSTER LOCATION #373 Chandra X-Ray Observatory Observations of Dynamically New Comet C/2012 S1 (ISON): First Detection of OVI Emission by the HRC-I from an X-Ray Bright Comet [#2065] We present 0.03–2.0 keV X-ray observations of the unexpectedly bright Comet ISON made by Chandra in Oct– Nov 2013, ~25 days before its perihelion disruption.

Wooden D. H. De Buizer J. M. Kelley M. S. Woodward C. E. Harker D. E. et al. POSTER LOCATION #374 SOFIA FORCAST Far-IR Photometry of Comet ISON and Constraints on Grain Size Distribuition [#2906] Thermal models to FORCAST observations of Comet ISON (rh = 1.2 AU) at 11, 19 and 32 µm show the coma has a steep size distribution of carbon-rich 0.7–1-µm grains.

Vervack R. J. Jr. Tamblyn P. M. Chapman C. R. Merline W. J. Murchie S. L. et al. POSTER LOCATION #375 Results from the MESSENGER Imaging Campaign of Comets C/2012 S1 (ISON) and 2P/Encke [#2585] Wide- and narrow-angle camera images of Comets C/2012 S1 (ISON) and 2P/Encke were acquired by MESSENGER during the close passes of both comets by Mercury.

Vervack R. J. Jr. Merkel A. W. McClintock W. E. Holsclaw G. M. Izenberg N. R. et al. POSTER LOCATION #376 Spectral Observations of Comets C/2012 S1 (ISON) and 2P/Encke Obtained by MESSENGER [#2553] Spectral observations of Comets C/2012 S1 (ISON) and 2P/Encke were acquired by the MESSENGER spacecraft during the close passes of both comets by Mercury.

Vodniza A. Q. Reyes K. P. Pereira M. R. Lopez J. P. POSTER LOCATION #377 The Comet ISON [#1070] In this work the comet’s and the orbital parameters are obtained using high-precision data. We have studied the comet since January 31, 2013. 45th Lunar and Planetary Science Conference (2014) sess721.pdf

Matzel J. E. P. Ishii H. A. Joswiak D. Brownlee D. Hutcheon I. D. POSTER LOCATION #378 Mn-Cr Isotope Systematics of Fayalite-Silica Intergrowths from the Stardust Mission to Comet 81P/Wild 2 [#1645] We measured Mn and Cr isotopes from fayalite-silica intergrowths in a particle from Comet 81P/Wild 2, and did not observe excess 53Cr outside analytical error.

Gicquel A. Milam S. N. Cordiner M. A. Villanueva G. Charnley S. B. et al. POSTER LOCATION #379 The Volatile Composition and Taxonomy of Comets C 2009/P1 (Garradd) and 103P/Hartley 2 from Ground-Based Radio Observations [#1957] Multiwavelength observations toward Comets C/2009 P1 and 103P/Hartley 2 to determine their taxonomy and some cosmogonic quantities from 12 m, SMT, JCMT, and GBT.
