Early Solar System Mixing Workshop
July 30-August 3, 2007
TIARA, 8F General Building II, National Tsing Hua University, Hsinchu, Taiwan


The Theoretical Institute for Advanced Research in Astrophysics (TIARA) of Academia Sinica and National Tsing Hua University (NTHU) will hold a five- day workshop to discuss the large scale mixing in the early Solar System that is evident from the initial result of the Stardust space mission to comet Wild-2. TIARA invites interested and qualified students and researchers in Taiwan to join us in this exciting opportunity to learn and discuss this hot topic with experts from all top research organizations of the world.


  1. Planetesimal formation inside and outside the snowline
  2. Heterogeneities at all scales
    Old dust from stars and ISM
    Last moment injection by nearby SN or AGB
    Solar system irradiation and thermal processing
    Star dust results for dust sample from comet
    Large heterogeneity resides in small (and old?) sites
    Planetary scale of heterogeneities
  3. Oxygen heterogeneities, the mystery at age 35
    Mechanism of mass-independent isotope fractionation
    New hypothesis of O-isotope
    O heterogeneity in the smallest scale
  4. The X-wind model
    Prediction, implication, and observational test

Organizing Committee


Each morning of the 5-day workshop will have two one hour lectures to give an overview of the topics. The afternoons will be devoted to informal discussions as well as short (10 min) presentations. Self-organized groups may retreat into offices for more technical and detailed discussion.

Registration Guideline

Interested researchers please send an email to and indicate your qualification and the extent of participation (auditing lectures, joining discussion, giving short presentation). The deadline for the email registration is July 15th, 2007. Because of the shortage of office space, the total number of full participants will be limited. Potential participants are encouraged to send your request ASAP. On the other hand we can rent larger lecture halls if there are a lot of people only interested in the lectures. Therefore, the registration is important for us to run a good workshop.

Meals & Lodging

Free lunch boxes will be provided to all registered participants. As to accommodation, we suggest that you directly contact nearby lodging such as the Berkeley Hotel.
