  1. 8 - IR Disk Emission & Grain Mineralogy

  2. Mg2SiO4 Green Sand Beach - Hawaii

  3. Winds of Gas & Dust from Evolved Stars “Gomez's Hamburger”

  4. The Red Rectangle

  5. Growth, Processing, Destruction in the Interstellar Medium

  6. ISM - “vanilla” silicates

  7. Accretion, Processing & Growth in Star-Forming Regions

  8. Formation of Planets in the Solar Nebula

  9. Young Pre-Main Sequence Disks “Older” PMS Disks - grain growth & settling Regenerated “Debris Disks” - replenished by collisions Zodiacal Light - Our Solar System Today

  10. TW Hydrae Association

  11. TW Hydrae - accreting sun-like star

  12. VLT Interferometer

  13. SAO 206462 VLTI (Fedele et al. 2008, A&A, 491, 809) different dates different baseline

  14. Annealing Condensed Silicate Smokes T = 1038 K

  15. T = 1027 K

  16. So, it’s all due to annealing, huh? How do you explain this then?

  17. Gas Flow in Disks

  18. Gas Flow in Disks

  19. Gas Flow in Disks

  20. Gas Flow in Disks HD 17255 - result of a hypervelocity collision? (Lisse et al. 2009, ApJ, 701).
