Dynamical and physical properties of comet–asteroid transition objects
In the last few years it has been pointed out that, from both physical and dynamical point of view, it is becoming more and more difficult to distinguish comets from asteroids and indeed there are some examples of small bodies first designated as comets which had, later, to be reclassified as asteroids and vice versa (Hartmann et al., 1990; McFadden, 1994). In order to investigate the evolution...
متن کاملA fully 3 - dimensional thermal model of a comet nucleus
A 3-D numerical model of comet nuclei is presented. An implicit numerical scheme was developed for the thermal evolution of a spherical nucleus composed of a mixture of ice and dust. The model was tested against analytical solutions, simplified numerical solutions, and 1-D thermal evolution codes. The 3-D code was applied to comet 67P/Churyumov-Gerasimenko; surface temperature maps and the inte...
متن کاملChondrulelike objects in short-period comet 81P/Wild 2.
The Stardust spacecraft returned cometary samples that contain crystalline material, but the origin of the material is not yet well understood. We found four crystalline particles from comet 81P/Wild 2 that were apparently formed by flash-melting at a high temperature and are texturally, mineralogically, and compositionally similar to chondrules. Chondrules are submillimeter particles that domi...
متن کاملPersistency Support for Mobile Objects in the COMET Heterogeneous Environment
Open distributed computing in an internetwork environment has gained considerable attention in the past few years. This paper presents COMET, a Common Object Management EnvironmenT, that investigates basic problems associated with distributed computing in an internet environment with mobile objects. COMET’s persistency support is based on typed memory, manipulated by persistent actions. The use...
متن کاملStochastic modeling for the COMET-assay
We present a stochastic model for single cell gel electrophoresis (COMET-assay) data. The distribution of length of DNA fragments is calculated according to a ’Random Breakage Model’ and the migration of DNA fragments among gel fibers is discussed. Essential to our approach is the use of point process structures, renewal theory and reduction to intensity histograms for further data analysis. Pa...
