Rotation State of Comet 103 P / Hartley 2 from Radio
نویسندگان
چکیده
The nuclei of active comets emit molecules anisotropically from discrete vents. As the nucleus rotates, we expect to observe periodic variability in the molecular emission line profiles, which can be studied through mm/submm spectroscopy. Using this technique Based on observations carried out with the IRAM 30-m, JCMT 15-m, and CSO 10.4-m telescopes. IRAM is supported by INSU/CNRS (France), MPG (Germany), and IGN (Spain). JCMT is operated by Joint Astronomy Centre and supported by STFC (UK), NRC (Canada), and NWO (Netherlands). CSO is operated by Caltech and supported through NSF grant AST-0540882 (USA).

Infrared spectral observations of comet 103 P / Hartley 2 by ISOPHOT ?
Spectral observations in the 2.5–12 μm range of comet 103P/Hartley 2 were performed on 1 Jan. 1998 by the ISOPHOT instrument, on board the Infrared Space Observatory. The obtained spectrum evidences intense bands at 2.66 and 4.26 μm, attributable to H2O and CO2, respectively. The derived molecular production rates are Q(H2O) = (3.1 ± 0.2) × 1028 molec. s−1 and Q(CO2) = (2.5 ± 0.3) × 1027 molec....
متن کاملTelescope Observations of the Nucleus of Comet 103 P / Hartley 2
We have used the Spitzer Space Telescope InfraRed Spectrograph (IRS) 22-μm peakup array to observe thermal emission from the nucleus and trail of comet 103P/Hartley 2, the target of NASA’s Deep Impact Extended Investigation (DIXI). The comet was observed on UT 2008 August 12 and 13, while 5.5 AU from the Sun. We obtained two 200 frame sets of photometric imaging over a 2.7 hr period. To within ...
متن کاملPhysical properties and dynamical relation of the circular depressions on comet 67P/Churyumov-Gerasimenko
Aims. We aim to characterize the circular depressions of comet 67P/Churyumov-Gerasimenko and investigate whether such surface morphology of a comet nucleus is related to the cumulative sublimation effect since becoming a Jupiter family comet (JFC). Methods. The images from the Rosetta/OSIRIS science camera experiment are used to construct size frequency distributions of the circular depression ...

متن کاملHigh-Resolution Bistatic Radar Imaging in Support of Asteroid & Comet Spacecraft Missions
High-resolution imaging of potential targets in advance of any spacecraft mission is important for reducing mission cost and risk and improving science returns. In particular, ground-based radar imaging provides highly-accurate ephemerides and shape and spin state information for objects that pass near the Earth. At higher resolution, radar images show surface features such as boulders and pote...
