We have developed a nonlinear fitting routine for the Harris current sheet based on magnetic data, and applied it to 71 plasma sheet crossings by Cluster. In most cases this simple fit appeared to represent the magnetic ...

Workshop material about THEMIS

The parameters of model auroral current systems were described in the previous chapter. To model the currents at any given time, these parameters must be adjusted to provide an optimal match to the available observations. ...

Physics distance education has grown rapidly in recent years. The theory part of a physics course taught in this way has much common ground with other courses. However, lab instruction is an important part of introductory ...

1-m class telescopes are arguably the workhorses of modern astronomy and represent an excellent return of science for a relatively modest capital investment. Such instruments can be used in large-field survey work, ...

Presentation from CASCA 2006 covering general aspects of co-orbital motion with emphasis on the fact that they would be good targets for space missions.

Presentation about stability of quasi-satellites, no movies.

2007 Athabasca Winter Workshop info + form

By studying orbits of asteroids potentially in 3:2 exterior mean motion resonance with Earth, Venus, and Mars, we have found plutino analogs. We identify at least 27 objects in the inner solar system dynamically protected ...
