The investigation of long GRBs\ntherefore requires modeling the propagation of ultra-relativistic blastwaves\nthrough the circumburst medium surrounding massive stars. We simulate the\nexpansion of an isotropic, adiabatic relativistic fireball into the wind-shaped\nmedium around a massive GRB progenitor. The circumburst medium is composed of a\nrealistically stratified stellar wind zone up to its termination shock,\nfollowed by a region of shocked wind characterized by a constant density. Aims:\nWe followed the evolution of the blastwave through all its stages, including\nthe extremely rapid acceleration up to a Lorentz factor 75 flow, its\ndeceleration by interaction with stellar wind, its passage of the wind\ntermination shock, until its propagation through shocked wind. Methods: We used\nthe adaptive mesh refinement versatile advection code to follow the evolution\nof the fireball. Results: We show that the acceleration from purely thermal to\nultra-relativistic kinetic regimes is abrupt and produces an internally\nstructured blastwave. We resolved the structure of this ultra-relativistic\nshell in all stages, thanks to the adaptive mesh. We comment on the dynamical\nroles played by forward and reverse shock pairs in the phase of interaction\nwith the free stellar wind and clearly identify the complex shock-dominated\nstructure created when the shell crosses the terminal shock.

The\nmethod is designed to eliminate the problems inherent in the rate-equation\nformalism to surface chemistry.

The surface chemical network consists of a small number\nof diffusive reactions that can produce molecular oxygen, water, carbon\ndioxide, formaldehyde, methanol and assorted radicals. METHOD: The simulation\nis started by running a gas-phase model including accretion onto grains but no\nsurface chemistry or evaporation. The starting surface consists of either flat\nor rough olivine. We introduce the surface chemistry of the three species H, O\nand CO in an iterative manner using our stochastic technique. Under the\nconditions of the simulation, only atomic hydrogen can evaporate to a\nsignificant extent. Although it has little effect on other gas-phase species,\nthe evaporation of atomic hydrogen changes its gas-phase abundance, which in\nturn changes the flux of atomic hydrogen onto grains. The effect on the surface\nchemistry is treated until convergence occurs. We neglect all non-thermal\ndesorptive processes. RESULTS: We determine the mantle abundances of assorted\nmolecules as a function of time through 2x10^5 yr. Our method also allows\ndetermination of the abundance of each molecule in specific monolayers.

This intersection has\nan unbounded component if and only if the function has no Baker wandering\ndomains. We also give estimates of the Hausdorff dimension and the upper box\ndimension of the Julia set of a meromorphic function with a logarithmic\nsingularity over infinity. The above theorems are deduced from more general\nresults concerning functions which have \"direct or logarithmic tracts\", but\nwhich need not be meromorphic in the plane. These results are obtained by using\na generalization of Wiman-Valiron theory. The method is also applied to complex\ndifferential equations.\n', '[{\"version\":\"v1\",\"created\":\"Fri, 20 Apr 2007 14:03:25 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 29 Jan 2008 16:26:06 GMT\"}]', '2008-09-28', '[[\"Bergweiler\",\"Walter\",\"\"],[\"Rippon\",\"Philip J.\",\"\"],[\"Stallard\",\"Gwyneth M.\",\"\"]]'),
