Presentation Transcript

  1. Diffuse Emission from Solar System Objects Fuzzy blobs I know and love Dr. Jeff Morgenthaler

  2. Outline • Examples of diffuse objects • Comets • Io plasma torus • Solar system itself • What are they? • Why are they interesting? • How are they studied?

  3. Comet Basics

  4. Anatomy of a comet Sun (106 km) Ion Tail Dust Tail Head Dust (1 m)

  5. Comet Wild 2 Comet Borrelly Comet Halley Comet Tempel 1 Cometary Nuclei ~10 km

  6. Comets: the most primordial objects in the solar system

  7. CN coma: Studying comets: remote sensing

  8. Comet Hale-Bopp Oxygen Coma

  9. McMath-Pierce Solar Telescope Facility

  10. Spatial Heterodyne Spectrometer: All reflective version

  11. Io Plasma Torus Io is the most volcanic body in the solar system

  12. Nearest astrophysical nebula Studied with: McMath-Pierce Solar Small telescopes

  13. Solar wind Heliosphere Local interstellar medium (solar wind ion) (cometary or interplanetary hydrogen) X-ray emission from comets and the solar system

  14. Diffuse X-ray Spectrometer What used to be thought of as interstellar X-ray emission may be entirely heliospheric

  15. Summary • Diffuse objects • Comets • Io plasma torus • Solar system itself • Interesting • Studied with resources available to St. Mary’s College of Maryland
