Pickup Protons and Water Ions at Comet Halley Comparisons with Giotto Observations
A quasi-linear diffusion model including both pitch angle and energy diffusion, adiabatic ompression and convective motion with the solar wind flow has been used to investigate the cometary ion pickup process along the Sun-comet line at comet Halley. The total pickup ion densities and magnetic turbulence spectrum levels observed by Giotto were used to constrain the quasi-linear model. Compariso...
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 کاملPolarimetric studies of comet Halley
In the present work, the non-spherical grain characteristics of comet Halley are analysed using the T-matrix method at λ= 0.365,0.485 and 0.684μm respectively. In order to analyse the polarisation data of comet Halley, the dust size distribution function derived by Das et al. (2004) for comet Halley is used in the present work. The size range of the grains is taken to be 0.01μm≤ s ≤ 3μm. Using ...
متن کاملThe Distributed Co in Comet Halley
Examination of the spatial distribution of CO intensity of Comet Halley indicates that a large fraction of CO originates from the refractory organic component in the coma, rather than directly from the volatiles in the nucleus. Based on the fluffy aggregate interstellar dust comet model, we have estimated the upper limits of the total amount of CO provided by coma dust. The implications from th...
متن کاملDetection of a New "chemical" Boundary at Comet Halley
Plasma observations near comet Halley indicate that around 1.6x105km from the nucleus a newly discovered sharp boundary (cometopause) separates the solar wind controlled external and the heavy cometary ion dominated internal regions. Such a discontinuity was previously not predicted by theoretical models. Inside the cometopause (in the cometary plasma region) the protons and heavy ions move wit...
