Gauge Symmetry of the N-body Problem in the Hamilton-Jacobi Approach by Michael Efroimsky ( )
2 editions published between 2003 and 2004 in English and held by 3 WorldCat member libraries worldwide
In most books the Delannay and Lagrange equations for the orbital elements are derived by the Hamilton-Jacobi method: one begins with the two-body Hamilton equations in spherical coordinates, performs a canonical transformation to the orbital elements, and obtains the Delannay system. A standard trick is then used to generalise the approach to the N-body case. We re-examine this step and demonstrate that it contains an implicit condition which restricts the dynamics to a 9(N-1)-dimensional submanifold of the 12(N-1)-dimensional space spanned by the elements and their time derivatives. The tacit condition is equivalent to the constraint that Lagrange imposed by "hand" to remove the excessive freedom, when he was deriving his system of equations by variation of parameters. It is the condition of the orbital elements being osculating, i.e., of the instantaneous ellipse (or hyperbola) being always tangential to the physical velocity. Imposure of any supplementary condition different from the Lagrange constraint (but compatible with the equations of motion) is legitimate and will not alter the physical trajectory or velocity (though will alter the mathematical form of the planetary equations)

[The Shaw Prize 2007 ( Visual )
1 edition published in 2007 in English and held by 2 WorldCat member libraries worldwide
A two-part special profiling the four laureates of this year's Shaw Prize. Professor Peter Goldreich has won the Astronomy Prize for his achievements in theoretical astrophysics and planetary sciences. Dr. Robert Lefkowitz has won the Life Science and Medicine Prize for his persistent breakthrough in the major receptor system that mediates the response of cells and organs to hormones and drugs
Gauge Freedom in the N-body Problem of Celestial Mechanics ( )
1 edition published in 2003 in English and held by 2 WorldCat member libraries worldwide
Whenever a standard system of six planetary equations(in the Lagrange, Delaunay, or other form) is employed, the trajectory resides on a 9(N-1)-dimensional submanifold of the 12(N-1)-dimensional space spanned by the orbital elements and their time derivatives. The freedom in choosing this submanifold reveals an internal symmetry inherent in the description of the trajectory by orbital elements. This freedom is analogous to the gauge invariance of electrodynamics. In traditional derivations of the planetary equations this freedom is removed by hand through the introduction of the Lagrange constraint, either explicitly (in the variation-of-parameters method) or implicitly (in the Hamilton-Jacobi approach). This constraint imposes the condition that the orbital elements osculate the trajectory, i.e., that both the instantaneous position and velocity be fit by a Keplerian ellipse (or hyperbola). Imposition of an supplementary constraint different from that of Lagrange (but compatible with the equations of motion) would alter the mathematical form of the planetary equations without affecting the physical trajectory

Final stages of planet formation by Peter Goldreich ( Visual )
1 edition published in 2004 in English and held by 1 WorldCat member library worldwide
The speaker discusses three major questions regarding solar system planets: what determined their number, why are their orbits nearly circular and coplanar and how long did they take to form?
Protostellar disks by Peter Goldreich ( Visual )
1 edition published in 1998 in English and held by 1 WorldCat member library worldwide
Lecturer describes hydrostatic, radiative equilibrium models for disks surrounding Tauri stars, presents calculations of both broad band and line radiation emitted by such disks, and discusses the stability of these disks
Chaos in our solar system by Peter Goldreich ( Visual )
1 edition published in 2009 in English and held by 1 WorldCat member library worldwide
"Chaos frustrates our ability to predict the future from present conditions in dynamic systems such as the weather and human behavior. With movies, demonstrations, and meteorites, Dr. Goldreich will reveal the frontiers of knowledge about the physics behind the origin of chaos in the climate variations on Mars, the unpredictable orbits of objects in space, and the path of meteorites from the asteroid belt to Earth."--From website

A Model for the 1612 MHz Masers in OH-IR Stars (13) ( Book )
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide
Shklovsky (1966) first suggested that OH masers might be pumped by the absorption of infrared radiation. Subsequently, the physics of the pump process was investigated by Litvak (1969) and by Litvak and Dickenson (1972). The present paper attempts to bring into sharper focus the essential features responsible for the inversion of the 1612 MHz transition in OH-IR stars
History of the lunar orbit by Peter Goldreich ( Book )
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
"Dynamic equations governing the evolution of the earth-moon system are derived and integrated back in time to determine its state at past epochs. The method is based on three time scales: short, determined by the revolution periods of the earth and moon around the sun and earth, respectively; intermediate, set by precessional motions of the moon's orbit plane and the earth's equator plane; and long, defined by the rate at which the frictional tides alter the state of the earth-moon system. The principle dynamic features of the sun-earth-moon system in the absence of tidal forces are described by precessional equations. It is shown that for each planet there is a critical distance such that a satellite orbit lying well within the distance will maintain a nearly constant inclination to the planet's equator plane; the present earth-moon distance is far greater than the critical distance. Equations of motion are presented for the slow changes in conserved quantities produced by frictionally retarded tides, the principal changes being produced by the tides raised on the earth by the moon, and smaller changes by the tides raised on the earth by the sun. Fission and capture theories of lunar origin and formation in earth orbit are mentioned."
