Meteoroids

Background credits: Fred Bruenjes

  • Interstellar meteoroids
  • Rare meteoroids
  • Meteoroid streams

Meteoroids

Background credits: Fred Bruenjes

  • Interstellar meteoroids
    • Small sizes and large sizes detected
    • Radar covers the sizes inbetween: no reliable detections
    • Interstellar gas-to-dust mass ratio
    • Information on interstellar processes & other stars
  • Rare meteoroids
  • Meteoroid streams

Meteoroids

Background credits: Fred Bruenjes

  • Interstellar meteoroids
  • Rare meteoroids
    • E.g. high altitude meteors
    • Largely un-characterized populations
    • Inform ablation physics
    • Interplanetary dust population
  • Meteoroid streams

Meteoroids

Background credits: Fred Bruenjes

  • Interstellar meteoroids
  • Rare meteoroids
  • Meteoroid streams
    • Meteor shower radiant and meteoroid orbits
    • Fine structure: uncertainty VS dynamics
    • Infer information on meteoroid streams & parent bodies
    • Discover new showers and explore solar system dynamics
