"The orbital elements of a meteoroid after its ejection from a comet."

PECINA P., SIMEK M.

Abstract (from CDS): This article examines the changes in the orbital

elements of particles ejected from the nucleus of an active comet. We

extend the work of Plavec (1957PAICz..30...93P) to include changes in all

the orbital elements resulting from the ejection process. We take into

account the constraints that must be met before a meteoroid particle can be

observed as a meteor. In addition we constrain particle ejection to take

place only on the sun-ward hemisphere of the cometary nucleus and only when

the comet is less than 1.88 AU from the Sun. For a given true anomaly of

the ejection event, our equations allow the determination of the speed and

direction of the ejected particle. Using the ejection of particles from

comet P/Swift-Tuttle, we applied our approach in an attempt to explain

whether or not a new filament of activity first seen in 1986 could be

attributed to particles ejected from the comet near the time of its 1862

perihelion passage. Observed Perseid meteor rates in 1986 - 1995, expressed

as a function of the solar longitude, cannot be used to uniquely determine

the time the corresponding particles were ejected from the parent comet.

The observed meteor shower activity could have been caused by particles

that were ejected from the nucleus at a variety of times, velocities and

ejection angles.
