Interstellar meteors - automatic and manual processing of the sample of hyperbolic events

ABSTRAKT / ABSTRACT :

One of the objectives of the DIMS (Dark matter and Interstellar Meteoroid Study) project is
to search for interstellar meteoroids. This, naturally, leads to investigation of hyperbolic
orbits calculated from meteor observations. However, it is not unusual to find many hyperbolic
events in individual meteor databases, in many cases about 10 percent out of all orbits
contained within the selected database. This percentage reflects the quality of the data
within the database. In general, these hyperbolic orbits are considered to be a result of
errors.
Continuing our previous work on the DIMS automatic pipeline system and data processing, we
will take a look at the sample of meteor data taken by the DIMS cameras, their orbits
calculated through automatic pipeline developed for the DIMS project and we will closely
discuss the hyperbolic events and their quality within the sample by comparing the results
obtained from the automatic pipeline with results from manual re-processing.
