Figure 3 Map of the deuterium abundance in solar system objects, plotted as D/H mole fraction. The carrier molecules for which deuterium has been measured in each object are labeled. The protosolar value, derived from measurements of He products of deuterium fusion in the Sun, and deuterium in the local region of the galaxy, is given, as are values for a carbonaceous chondrite meteorite, the Earth s oceans, and comets (source...

In 1917 Harlow Shapley mapped the extent of the galaxy by counting globular clusters rather than stars. Globular clusters are collections of roughly 100,000 stars. They can be seen from the distant reaches of the Milky Way. Just as Copernicus before him concluded that Earth is not the center of the solar system, Shapley proved that the solar system was not at the center of the galaxy. Since Shapley s time, astronomers have refined his technique and discovered new ways to deduce the size, structure, and contents of the Milky Way. [Pg.350]

The most detailed v — l maps of the Milky Way are the Dame et al., 2001, observations of molecular gas using CO as a tracer. In this data set, we can clearly identify two different arms (with a ir/2 phase separation, i.e., probably part of an m = 4 set) The Carina arm which is located inwards to the solar galactic radius 11.. and the Perseus arm, externally located relative to Rq. The solar system is located in the Orion arm. We perform our analysis on the Sagittarius-Carina arm (Naoz and Shaviv 2004), which has the richest cluster data. [Pg.208]

Abstract The periodic orbits play an important role in the study of the stability of a dynamical system. The methods of study of the stability of a periodic orbit are presented both in the general case and for Hamiltonian systems. The Poincare map on a surface of section is presented as a powerful tool in the study of a dynamical system, especially for two or three degrees of freedom. Special attention is given to nearly integrable dynamical systems, because our solar system and the extra solar planetary systems are considered as perturbed Keplerian systems. The continuation of the families of periodic orbits from the unperturbed, integrable, system to the perturbed, nearly integrable system, is studied. [Pg.43]

Meteorites "map the Solar System by having specific oxygen isotopic compositions, a major element in all but the irons. Since its high chemical reactivity causes oxygen to form numerous compounds, it exists in many meteoritic minerals, even in silicate inclusions in iron meteorites. Elsewhere in this volume, Clayton (5) discusses meteoritic oxygen isotopic differences and processes that established these [cf (/)]. [Pg.167]

Radio Astronomy. Most radio astronomy applications operate in the microwave spectrum. Usually, naturally occurring microwave radiation is observed however, radio astronomy has been used to measure distances precisely within the solar system. Radio astronomy has also been employed to map the surface of Venus, which is not visible via optical telescopes because of its dense cloud cover. The technology has expanded astronomical knowledge and has led to the discovery of new objects, including radio galaxies, pulsars, and quasars. Radio astronomy allows objects that are not detectable with an optical telescope to be seen. These objects are some of the most extreme and... [Pg.1224]

Chemists show the lines between solid, liquid, and gas with phase diagrams. These graphs are maps in which pressure increases from west to east and temperature increases from south to north (or vice versa). Solids are always in the southwest corner, gases are always on the northeast, and liquids are in-between. These show what will happen when everything is well mixed and has had time to equilibrate at a certain temperature and pressure. Figure 4.4 shows phase diagrams for the solar system, with each planet or moon s surface conditions labeled. [Pg.75]

In order to easily construct an illustrative map of the infrared sky, the following somewhat arbitrary rules were adopted (1) It was decided to exclude the bodies of the solar system, realizing that this important area would be covered later in the conference. (2) Emphasis would be placed on representing as many different types or classes of sources as can be clearly discerned with existinq data. (3) Each class of object wou d, in general, be represented by its "brightest members". [Pg.7]

Nucleogenesis in the interior of massive stellar objects yields 100 natural elements of composition Zj A - Z) = 1. Because of radioactive decay at reduced pressure in intergalactic space, the stability ratio converges as a function of mass number to a value of t at yl = 267 = (A — Z ) t> = Z. As a result, only 81 stable elements survive in the solar system as a periodic array conditioned by r. The observed periodicity corresponds to a Ford-circle mapping of the fourth-order unimodular Farey sequence of rational fractions. [Pg.90]

A very wide range of astrophysical problems can be tackled with ISOCAM, for example - solar system studies structure of zodisM l bands and cometary trails, spectral maps of comets - interstellar matter and staff formation nature of 12 m emission of large molecules or grains, grain formation and destruction, interaction between supemovae and the interstellar medium... [Pg.262]

A more detailed overview of the main components of the GEOS-DAS system the forecast model, the input data (total ozone observations from Total Ozone Mapping Spectrometer /TOMS/ and vertical ozone profiles from the Solar Backscatter Ultra Violet instrument /SBUV/, the analysis scheme and its implementation could be easy found in the paper of Riishojgard [19]. [Pg.374]

On the basis of the studies reported in the last few years, it is elear that the reeent significant progress both in mapping the natural systems and in designing sophisticated artificial systems has been made possible by the recent notable advaneements of experimental techniques and made-to-order synthesis. Beeause both the experimental techniques and made-to-order synthesis are continuing to improve fast at the moment, further impressive developments in the field are expected in the near future [48], so bringing the photochemical conversion of solar energy eloser. [Pg.3385]

When such a map has been constructed, it can be used to select semiconductors of different bandgap, but the same lattice constant, so that the lattice matching which is so desirable in a heterojunction can be made between a specified wide bandgap window semiconductor and a series of photovoltaically active alloy semiconductors. For example. Fig. 10 shows the iso-lattice constant line with a lattice constant value equal to that of CdS (5.82 eV). The bandgaps of semiconductors which have this lattice constant range from about 1.06 eV to 1.80 eV this range makes the Cu-Ag-In-S-Se alloy system an attractive possible source of materials to be used in solar cells of tandem systems. A description of experiments on this and other ternary alloy systems is the subject of another section of this chapter. However, before we return to that matter we shall first consider optimum design of individual cells for incorporation into the system. [Pg.174]
