The main differences between the various simulation experiments were the duration of the insolation period, the intensity of the insolation, the time profile of the insolation, and the composition of the samples.

Sekanina a, Fanale and Salvail Basic Equations the heat transfer equation, the boundary conditions refer to the flux. Features larger than this should be modeled by an ellipsoidal nucleus.

BibTeX bibliography

When warmed to about K, amor- phous ice transforms into a cubic crystalline form and then under confine- ment pressure and at temperatures of K, into the stable hexagonal crystalline form.

For example, it is impossible to reproduce the total energy spectra or to know the total ion fluorescence in a particular astrophysical morfan3.dvi. Instead, we concentrate on modeling aprpoximation to understand the reality of the physical processes occurring in comet nuclei. Laboratory Simulations 21 2. The initial conditions must be guessed.

Ions are not presented in this table because the differences of the interstellar radiation field and that of the Sun are too large to make such a comparison meaningful. Low temperatures are a necessary but not a sufficient condition for the formation of amorphous water ice.

For gas diffusion, we showed in Chapter 3 that thermodynamic condi- tions within the nucleus result in very low gas densities. Once a comet enters the inner Solar System, it progressively decays with each orbit. The interaction between appfoximation may therefore be neglected. Our aim is to assess the accuracy of numerical models and to identify the main factors that will affect it.

The data from these investiga- tions have been supplemented by observations of two unusually active recent comets: The size dis- tribution was poorly constrained by such experiments, which can only be representative of emitted dust properties and not of nucleus bulk properties. Making this assumption, the results of the analyses are given in Table 2.

The Structure of Comet Nuclei experiments by Pirronello et al. Its density changes as a function of depth because appgoximation sublimation of ices and condensation of vapours.

Convex shapes of the temperature profiles below energy sinks sublimation fronts were observed as a result of the heat-carrying, inward-flowing vapour and subse- quent freeing of latent heat after condensation of the gas at cooler, deeper layers. Water solid line and CO dashed line fluxes com- puted from algorithm C1 with parameters given in Table 7.

The particles are initially embedded in the porous ice matrix and as the ice sublimates from the surface, the embedded particles become progressively free appfoximation subject to the drag exerted by the escaping gas.

The identification of the CHON particles polycondensates of organic materials associated with dust par- ticles led to the identification of the distributed sources of some minor species. Porosity in general and pore size in particular may appdoximation internal gas pressure in the nucleus.

Near the subsolar area, such shadows are very small or may not exist at all. The next line of spheres is parallel to the first line at a distance 2r p centre to centre of just touching spheres.

This will result in a centre of mass speed v 0z0 the bulk or drift 0 motion and velocities relative to v 0z that obey the drifting Maxwell distri- bution function. However, one can reasonably expect an irregular shape and probably a dark surface for most comet nuclei.

Straight parallel tubes on a square mesh. Momentum Balance 61 We note that Eq. Other mechanisms of their disintegration may be rapid spin or elec- tric charging. Since all the parameters can be measured independently, the relation was tested experimentally and was found to be in good agreement with theoretical results. The conservation laws are expressed by means of time-dependent, partial differential equations having the following general form: At large heliocentric and therefore large geocentric distances, it is difficult to spatially resolve the nucleus.

Strazzulla and Johnson suggested that in the Oort cloud the external 0. Amorphous water ice can persist for timescales comparable to the age of the Solar System because an activation energy barrier prevents its transition into crystalline ice. From an observational point of view, the distinction between asteroids and comets is not as clear as it was in the past. This required a source of CO much larger than could be provided by a thin surface layer. The green squares represent the change in enthalpy for sublimation into vacuum as obtained by Delsemme and Miller based on data from Washburn
