Satellites probabilities

Predictions infalling satellite probably has to be large thin disk younger than thick disk and an age gap between the disks likely that the abundance trends differ gradients will be preserved (if they exist in pre-existing thin disk) star formation in original thin disk could be as long as needed (e.g. to create the knee in the a-element trends)... [Pg.19]

Satellite astronomical observations remove the problems of the atmospheric absorption windows but require more sophisticated orbital spacecraft. Telescopes mounted on aircraft in part can achieve better results but state-of-the-art results are obtained from orbiting satellites. Probably the most successful satellite telescope for public... [Pg.55]

To be honest, I don t really believe 1 get unwell. I believe 1 lose control and The Controller comes in and takes over... I actually like having him around because sometimes 1 can t know what to do and he tells me what to do... There s something scary about it at the same time, because you have to trust him, and 1 don t really trust him, not completely... I m scared a litde bit about what he can make me do. On the whole, it s a comfort... When 1 was jogging, I sometimes got into trouble with men in the dark park and he made me go whooshl Really fast. Yeah, seriously. Sometimes I drop something and he tells me I ve dropped it. 1 don t know I ve dropped it, but he s seen from somewhere, satellite probably. [Pg.255]

Water and carbon play critical roles in many of the Earth s chemical and physical cycles and yet their origin on the Earth is somewhat mysterious. Carbon and water could easily form solid compounds in the outer regions of the solar nebula, and accordingly the outer planets and many of their satellites contain abundant water and carbon. The type I carbonaceous chondrites, meteorites that presumably formed in the asteroid belt between the terrestrial and outer planets, contain up to 5% (m/m) carbon and up to 20% (m/m) water of hydration. Comets may contain up to 50% water ice and 25% carbon. The terrestrial planets are comparatively depleted in carbon and water by orders of magnitude. The concentration of water for the whole Earth is less that 0.1 wt% and carbon is less than 500 ppm. Actually, it is remarkable that the Earth contains any of these compounds at all. As an example of how depleted in carbon and water the Earth could have been, consider the moon, where indigenous carbon and water are undetectable. Looking at Fig. 2-4 it can be seen that no water- or carbon-bearing solids should have condensed by equilibrium processes at the temperatures and pressures that probably were typical in the zone of fhe solar... [Pg.22]

The surface of Venus is hidden under an unbroken layer of clouds 45-60 km above it. Recently, the planet has been subjected to a complete cartography by radar satellites. Its atmosphere contains 96% CO2 by volume, the remainder consisting of N2, SO2, sulphur particles, H2SO4 droplets, various reaction products and a trace of water vapour. The water is probably subject to photolytic decomposition. Noble gases are more abundant than on Earth 36Ar by a factor of 500, neon by a factor of 2,700, and D (deuterium) by a factor of 400. [Pg.44]

So far, we have not considered the so-called longitudinal two-spin order, represented by the product operator9 2J ff, a quantity related to the polarization of nuclei A and B. This spin state can be created in different ways. The easiest way is probably to let the system evolve under the sole Jab coupling so as to obtain an antiphase doublet, for instance the B antiphase doublet represented by 2//Vf (corresponding to the two proton-carbon-13 satellites in an antiphase configuration). [Pg.99]

For example, in a radical with six equivalent carbon atoms (e.g., benzene anion radical), the probabilities are P0 = 0.936, Pi = 0.062, P2 = 0.0017, P3 = 0.00003, etc. In practice, we would probably see only the central line with intensity 0.936 and a pair of satellites with intensity 0.031, corresponding to splitting of the center line by a single 13C (the intensity is distributed between the two resonances). [Pg.38]

How then, can one recover some quantity that scales with the local charge on the metal atoms if their valence electrons are inherently delocalized Beyond the asymmetric lineshape of the metal 2p3/2 peak, there is also a distinct satellite structure seen in the spectra for CoP and elemental Co. From reflection electron energy loss spectroscopy (REELS), we have determined that this satellite structure originates from plasmon loss events (instead of a two-core-hole final state effect as previously thought [67,68]) in which exiting photoelectrons lose some of their energy to valence electrons of atoms near the surface of the solid [58]. The intensity of these satellite peaks (relative to the main peak) is weaker in CoP than in elemental Co. This implies that the Co atoms have fewer valence electrons in CoP than in elemental Co, that is, they are definitely cationic, notwithstanding the lack of a BE shift. For the other compounds in the MP (M = Cr, Mn, Fe) series, the satellite structure is probably too weak to be observed, but solid solutions Coi -xMxl> and CoAs i yPv do show this feature (vide infra) [60,61]. [Pg.116]

In light lanthanides (La, Ce, Pr, Nd) the pulled down 4f state is nearly localized and hybridizes only weakly with conduction states. The bandwidth W4f will be very narrow, U high and negative, and the occupation probabiUty by conduction electrons rather low. This results in the occurrence of shake-down satellites at a lower binding energy for lanthanides, accompanying a poorly screened main peak (Fig. 7 a). When proceeding to heavier lanthanides, the occupation probability and the intensity of the shake-down satellite are depressed the symmetric, poorly screened core level is left, i.e. the 4f states are completely localized. [Pg.216]

Is not known Thus it seems reasonable that one or more of the satellite peaks of the 1,4 peaks might arise from 1,2 methylene carbons as shown in VII and VIII. It is not certain what the multiple peaks near 35 ppm represent, but they probably arise from C-13c spin-spin coupling in oligomers with a DP of 2 or more The sharp peak at 29.70 is due to the methyl carbons of the reacted t-butyl group ... [Pg.380]

Ice mantles are important constituents of interstellar grains in molecular clouds, and icy bodies dominate the outer reaches of the solar system. The region of the solar system where ices were stable increased with time as the solar system formed, as accretion rates of materials to the disk waned and the disk cooled. The giant planets and their satellites formed, in part, from these ices, and probably also from the nebular gas itself. [Pg.355]

The Cr 2p3a binding energies (XPES) increase from Cr(CNPh)6 to [Cr(CNPh)6]+ to [Cr(CNR)6]2+, the values being 574.5, 575.3 and 576.7 eV respectively.22 29 The shake-up satellite structure associated with the N Is and C Is binding energies in these spectra most probably arises from M (d)- it (CNAr(R) excitations accompanying the primary photoemission. [Pg.708]
