The Spectrum of Comet Austin
as Fig. 1 in a slightly modified form. Green et at. note that the 1128 A transition is optically forbidden because it occurs between two even parity oxygen atom states, whereas the selection rules permit transitions between odd and even parity only (2). However, they do not say that the 79176 A (7.92 gum) transition is equally forbidden, as both relevant states are odd (3). It is also forbidden...
متن کاملIrregular Particles in Comet C/1995 O1 Hale-bopp Inferred from Its Mid-infrared Spectrum
An analysis of the Infrared Space Observatory (ISO) infrared spectra of comet C/1995 O1 Hale-Bopp has been conducted. The particles in the coma are assumed to be irregular aggregates that are built by a diffusionlimited aggregation (DLA) procedure and are composed of olivine, both amorphous and crystalline, and glassy carbon. To simulate the morphological structure of the interstellar dust, the...
متن کاملWater in the near-infrared spectrum of comet 8P/Tuttle
High-resolution spectra of comet 8P/Tuttle were obtained in the frequency range 3449.0– 3462.2 cm−1 on 2008 January 3 UT using CGS4 with echelle grating on United Kingdom Infrared Telescope. In addition to observing solar pumped fluorescent lines of H2O, the long integration time (152 min on target) enabled eight weaker H2O features to be assigned, most of which had not previously been identifi...
متن کاملWater in the Near IR spectrum of Comet 8P/Tuttle
High resolution spectra of Comet 8P/Tuttle were obtained in the frequency range 3440.6–3462.6 cm on 3 January 2008 UT using CGS4 with echelle grating on UKIRT. In addition to recording strong solar pumped fluorescent (SPF) lines of H2O, the long integration time (152 minutes on target) enabled a number of weaker H2O features to be assigned, most of which had not previously identified in cometar...
متن کاملOp-gbev130144 1886..1901
Transposable elements (TEs) are a dominant feature of most flowering plant genomes. Together with other accepted facilitators of evolution, accumulating data indicate that TEs can explain much about their rapid evolution and diversification. Genome size in angiosperms is highly correlated with TE content and the overwhelming bulk (>80%) of large genomes can be composed of TEs. Among retro-TEs, ...
