... 297 ­ 300, 2004 Photoluminescence Study of the Two-Dimensional Tetragonal and Rhombohedral Polymers of C60 at High Pressure K. P. Meletov* Institute of Solid State Physics, RAS, Chernogolovka, Moscow Region, Russia ABSTRACT The pressure behavior of the photoluminescence (PL) spectra of the planar polymeric phases of C60 have been studied at pressure up to 4 GPa. ... Figure 2 shows the pressure dependence of the principal bands in the PL spectra of the 2D-R, 2D-T polymers and pristine C60. ...

The aromatic features in M101 were studied spectroscopically and photometrically using observations from all three instruments on the Spitzer Space Telescope. The global SED of M101 shows strong aromatic feature (commonly called PAH feature) emission. ... This implies that the weakening of the aromatic emission in massive star-forming regions is due primarily to processing of the dust grains in these environments, not to differences in how they form. ...

Pulsars can be used to study the strong nuclear force. The density of matter at the center of neutron stars is one or two orders of magnitude larger than the density of atomic nuclei. ... Very "soft" EOSs predict lower pressures for a given density, i.e., highly compressible matter. ... If more precise measurements can confirm this high value, then many model EOSs for dense matter can be ruled out. ... Another way of studying the behavior of super-dense matter is to find fast pulsars. ...

... Figure 1: Evolution of 1:6 resonant argument of 1P/Halley over 6000 years from 2404 B.C. Abstract . ... Many previous works have shown the active role of mean motion resonances in the evolution of various meteoroid streams. Here we look at how various resonances, especially the 1:6 and 2:13 mean motion resonances with Jupiter, affect comet 1P/Halley and thereby enhance the chances of meteoroid particles getting trapped in resonance, leading to meteor outbursts in some particular years. ...

... We present several applications of the AIPS++ environment as applied to the development of the Green Bank Telescope as well as current astrophysical problems. ... In particular, the Green Bank Telescope (GBT) project requires AIPS++ as an analysis environment. To accommodate and facilitate the GBT development, several sets of tools have been fashioned within AIPS++ at several points along the data path, from general calibration routines and data quality assessment to analysis and modeling. ...

... Driver ID: LOCAL . This is a hack to allow a machine to use its own system clock as a reference clock, i.e., to free-run using no outside clock discipline source. ... Another application for this driver is if a particular server clock is to be used as the clock of last resort when all other normal synchronization sources have gone away. ... This driver provides a mechanism to trim the local clock in both time and frequency, as well as a way to manipulate the leap bits. ... Not used by this driver. ...
