Interstellar Dust, Formation, Dust Detectors
Scientific paper
Dust particles, like photons, are born at remote sites in space and time. From knowledge of the dust particles' birthplace and their bulk properties, we can learn about the remote environment out of which the particles were formed. This approach is called dust astronomy which is carried out by means of a dust telescope on a dust observatory in space. It can provide valuable information about the particles' birthplace which may not be accessible by other techniques. Targets for a dust telescope are interstellar, cometary, and asteroidal dust. Interstellar and interplanetary dust particles are separated by in-situ dust detectors with narrow apertures and by the measurements of the electric charge signals that are induced when the charged grains fly through the detector. Modern in-situ dust detectors are capable of providing mass, speed, physical and chemical information of dust grains in space.
