Migration of interplanetary dust.
We numerically investigate the migration of dust particles with initial orbits close to those of the numbered asteroids, observed trans-Neptunian objects, and comet Encke. The fraction of silicate asteroidal particles that collided with the Earth during their lifetime varied from 11% for 100 micron particles to 0.008% for 1 micron particles. Almost all asteroidal particles with diameter d >/= 4...
متن کاملInterplanetary Stream Interfaces
At 1 AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed. In some cases this is a tangential discontinuity; in others it is probably evolving into a tangential discontinuity. It is suggested that stream interfaces form in the interplan...
متن کاملInterplanetary Dust Community
Imagine a box filled with particles from hundreds of thousands of small bodies throughout the solar system, including asteroids, comets, Trojans, Centaurs, KBOs and even from other stars. Each particle contains information about the object from which it came and the space environment through which it has traveled. Largely collected near the Earth’s orbit and on the Earth itself, this box of par...
متن کاملA Flexible Interplanetary Internet
Work on delay tolerant networking has grown out of work on an interplanetary Internet and aims to provide a type of network stack which is specifically designed for use in networks with inherently long transit times often also involving highly constrained network nodes. We present an update on progress with this technology and describe how it might be used to construct a flexible network to sup...
متن کاملInterplanetary Field Visualization System
A prototype system of visualizing interplanetary field has been developed using an immersive projection display. The system enables a user to observe global behavior of the interplanetary plasma in a virtual environment. The velocity and density fluctuations are measured with interplanetary scintillation method, and are analyzed by using computer topography technique. The analysis has produced ...
