The science behind the falling stars as revealed by the All-Sky Meteor Orbit System

Meteoroids are fragments of asteroids, comets, moons and planets. The meteoroids that enter Earth's atmosphere create spectacular events -- the falling stars, delivering thousands of tons of interplanetary matter to Earth annually. A typical meteor shines for only a fraction of a second, but this short time interval is sufficient to learn about its orbit and physical properties. All-sky meteor detection and characterization is needed for continuous monitoring of the meteoroid flux, particularly in the detection of weak or short-duration meteor showers. Multi-station detection of a single meteor provides heliocentric orbits for meteoroids that can be used for population studies and searches for their parent bodies. Spectral observations of the emission lines of meteoric plasma is essential for understanding the original and evolved physical properties of meteoroids. We have developed AMOS (All-Sky Meteor Orbit System), an original automated camera system, to detect and characterize meteors. The network of AMOS cameras has been deployed in Slovakia since 2009, at the Canary Islands since 2015, and in Chile since 2016. AMOS would like to find a home in Hawaii to increase its global coverage and monitor the influx of millimeter to meter sized objects because the sky above the Pacific Ocean has never been systematically monitored for meteor activity.
