An 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 کاملGround-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 کاملLower Hybrid Waves Upstream of Comets and Their Implications for the Comet Halley Bow Wave
Observed and theoretical features concerning the nature of so-called cometary "bow shocks" or "bow waves" are discussed. Collective plasma effects associated with the presence of pickup ring ions (protons and water ions) in the vicinity of the supermagnetosonic to submagnetosonic transition region in the quasi-perpendicular limit are considered; the linear and nonlinear evolution of instabiliti...
متن کاملFrom interstellar dust to comets: the extended CO source in comet Halley
Some simplemolecules in comet comae like CO, C2, C3, CN, H2CO appear to be distributed in such a way that they are neither directly emitted from the nucleus surface nor created as daughter molecules from more complex gas phase species. The only remaining possible source is the organic component in comet dust. The requirements imposed on the comet dust grains by the distributed CO emission are t...
