The impulse approximation and full N-body experiments are used to investigate the changes
in mass and binding energy which result from gravitational encounters between spherical …

En este documento, se reporta una investigación documental cuyo objetivo es identificar el
impacto de la aplicación de la metodología 5S sobre la gestión de seguridad y salud laboral …

We report new photometry and radial velocities for almost 500 stars from the Lowell Proper
Motion Catalog. We combine these results with our prior sample and rederive stellar …

Based on our expanded sample of metallicities and kinematics for a large sample of stars
selected from the

We explore test particle orbits in the orbital plane of eccentric stellar binary systems, searching
for ‘invariant loops’: closed curves that change shape periodically as a function of binary …

A method of classifying generic orbits in arbitrary 2D and 3D potentials is presented. It is
based on the concept of spectral dynamics introduced by Binney &38; Spergel that uses the …

… In the present paper, we extend the collapse simulations of Merritt and Aguilar (1985) to …
Our code is identical to the one used by Merritt and Aguilar (1985) in their investigation of the …

We examine the stability of spherical, non-rotating galaxies using an N-body code to evolve
a set of initially equilibrium models generated from three distribution functions. All the …

A simple model for collision-induced changes in the structure of a nonrotating spherical
galaxy is presented, and its predictions are compared with N-body simulations. The numerical …

We report [Fe/H] results for a sample of five high-velocity metal-poor halo population stars and
five comparably metal-poor stars thought to have kinematics typical of an older, hotter disk …
