The cometary and asteroidal origins of meteors [PDF]

A quantitative examination of the gravitational and nongravitational changes of orbits shows that for larger interplanetary bodies the perturbations by Jupiter strongly predominate over all other effects, which include perturbations by other planets ...

Heating of near-Earth objects and meteoroids due to close approaches to the Sun

, 2009
It is known that near-Earth objects (NEOs) during their orbital evolution may often undergo close approaches to the Sun. Indeed it is estimated that up to ~70% of them end their orbital evolution colliding with the Sun.

Physical properties of interplanetary grains [PDF]

Morphological analyses of micrometeorite craters found on lunar rocks and laboratory simulation experiments are used to formulate a meteoritic interplanetary dust particle for optical scattering calculations that is roughly spherical and has a density of

The 15 years of comet photometry: A comparative analysis of 80 comets [PDF]

In 1976, a program of narrowband photometry of comets was initiated that has encompassed well over 400 nights of observations. To date, the program has provided detailed information on 80 comets, 11 of which were observed during multiple apparitions. The

Meteoroid capture cell construction [PDF]

, 1976
A thin membrane covering the open side of a meteoroid capture cell causes an impacting meteoroid to disintegrate as it penetrates the membrane.

Discovery of a new branch of the Taurid meteoroid stream as a real source of potentially hazardous bodies

, 2017
Taurid meteor shower produces prolonged but usually low activity every October and November. In some years, however, the activity is significantly enhanced.

A review of micrometeoroid flux measurements and models for low orbital altitudes of the Space Station [PDF]

A review of meteoroid flux measurements and models for low orbital altitudes of the Space Station has been made in order to provide information that may be useful in design studies and laboratory hypervelocity impact tests which simulate micrometeoroids ...
