Effects of Nitrogen Photoabsorption Cross Section Resolution on Minor Species Vertical Profiles in Titan's Upper Atmosphere

The significant variations in both measured and modeled densities of minor species in Titan's atmosphere call for the evaluation of possible influencing factors in photochemical modeling. The effect of nitrogen photoabsorption cross section selection on the modeled vertical profiles of minor species is analyzed here, with particular focus on C2H6 and HCN. Our results show a clear impact of cross sections used on all neutral and ion species studied. Affected species include neutrals and ions that are not primary photochemical products, including species that do not even contain nitrogen. The results indicate that photochemical models that employ low-resolution cross sections may significantly miscalculate the vertical profiles of minor species. Such differences are expected to have important implications for Titan's overall atmospheric structure and chemistry.NASA Outer Planet Research program NNH12ZDA001NInstitute for Computational Engineering and Sciences (ICES

United Incandescent

Croydon, 1997. Henrik and Matthew haven't gone round with a damp cloth for several years. Jessica is about to become a Blair babe. Then an unexpected ring at the doorbell precipitates a chain-reaction of discoveries and confessions. For idealistic Conmunist Henrik, his housebound son Matthew and his politically ambitious daughter Jessica, a lifetime built on secrets and half-truths is about to come tumbling down. The events of the last forty years from Henrik's days packing light-bulbs on the factory floor of United Incandescent, to the fall of the Wall, to the arrival of the mysterious Anna from Budapest all conspire to tell a different story from the one that Henrik has carefully constructed in his memoirs...with extraordianry consequences for his children. A passionate, quirky and epic family drama about love, loyalty, lies and the Left

Quark confinement and the bosonic string

Using a new type of simulation algorithm for the standard SU(3) lattice gauge theory that yields results with unprecedented precision, we confirm the presence of a $\gamma/r$ correction to the static quark potential at large distances $r$, with a coefficient $\gamma$ as predicted by the bosonic string theory. In both three and four dimensions, the transition from perturbative to string behaviour is evident from the data and takes place at surprisingly small distances.Comment: TeX source, 21 pages, figures include

Vector meson radiation in relativistic heavy-ion collisions

The sigma-omega model in mean-field approximation where the meson fields are treated classically, describes much of observed nuclear structure and has been employed to describe the nuclear equation of state up to the quark-gluon phase transition. The acceleration of the meson sources, for example, in relativistic heavy-ion collisions, should result in bremsstrahlung-like radiation of the meson fields. The many mesons emitted serve to justify the use of classical meson fields. The slowing of the nuclei during the collision is modeled here as a smooth transition from initial to final velocity. Under ultra-relativistic conditions, vector radiation dominates. The angular distribution of energy flux shows a characteristic shape. It appears that if the vector meson field couples to the conserved baryon current, independent of the baryonic degrees of freedom, this mechanism will contribute to the radiation seen in relativistic heavy-ion collisions. The possible influence of the quark-gluon plasma is also considered.Comment: 17 pages, 4 postscript figures. Uses elsart.sty and psfig.sty. Improved motivation and typographical corrections.

Photochemistry and Haze Formation

One of the many exciting revelations of the New Horizons flyby of Pluto was the observation of global haze layers at altitudes as high as 200 km in the visible wavelengths. This haze is produced in the upper atmosphere through photochemical processes, similar to the processes in Titan's atmosphere. As the haze particles grow in size and descend to the lower atmosphere, they coagulate and interact with the gases in the atmosphere through condensation and sticking processes that serve as temporary and permanent loss processes. New Horizons observations confirm studies of Titan haze analogs suggesting that photochemically produced haze particles harden as they grow in size. We outline in this chapter what is known about the photochemical processes that lead to haze production and outline feedback processes resulting from the presence of haze in the atmosphere, connect this to the evolution of Pluto's atmosphere, and discuss open questions that need to be addressed in future work
