Ground-based Optical and Spitzer Infrared Imaging Observations of Comet 21p/giacobini-zinner
We present ground-based optical and Spitzer Space Telescope infrared (IR) imaging observations of the ecliptic (Jupiter-family) comet 21P/Giacobini-Zinner, the parent body of the Draconid meteor stream, during its 2005 apparition. The onset of nucleus activity occurred at a pre-perihelion heliocentric distance, rh 3.80 AU, while post-perihelion 21P was dusty (peak Afρ = 131 cm−1) and active out...
متن کاملAn Infrared Investigation of Volatiles in Comet 21P/Giacobini–Zinner
We obtained high resolution (λ/δλ∼ 10,000–20,000) infrared (IR) spectra of Comet 21P/Giacobini–Zinner (GZ) at five different wavelengths between 1.9 and 5.0 μm during 25–29 October 1998 using CSHELL at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea. We also obtained a moderate resolution (λ/δλ∼ 680) spectrum covering the wavelength range from 3.082 to 3.720 μm on 29 October 1998 using...
متن کاملIon Distribution Functions in the Vicinity of Comet Giacobini-zinner
Photoionization of neutral molecules in the coma surrounding a comet produces heavy ions which contaminate and mass-load the solar wind. Cometary ion distribution functions in the vicinity of comet Giacobini-Zinner (G/Z) are calculated using a Monte Carlo method. The distribution function calculated behind the shock has both cold (= 2 keV) and hot (-40 keV) components.
متن کاملThe Accuracy of Ground-Based Optical Interferometry Observations
The problem of wide-angle astrometry via interferometry is to recover the two coordinates for each star from the observed delays. In the absence of atmospheric turbulence, the geometrical delay can be dened as: dG;ij(t) dj(t) di(t) = Bij(t) ŝ0 Cij . Here the geometrical delay is the di erence between the delay line lengths di and dj that is required to equalize the e ective optical paths from t...
متن کاملDiffraction-limited Imaging with Ground-based Optical Telescopes
The construction of diffraction-limited images with ground-based optical telescopes by means of closure-phase observations is explored. The effect of redundant baselines on closure-phase observations is analyzed, and it is shown that for bright objects a nonredundant-mask approach is superior to the use of the full aperture. Observations of closure phase with a nonredundant mask on the 200 in. ...
