Forwarded at the request of Fred Ciesla: ------------------------------ Dear All: I would like to announce that the *Gordon Research Conference on the Origins of Solar Systems* will be held this year from *June 28-July 3, 2015* at Mount Holyoke College in South Hadley, MA. This interdisciplinary meeting is held every two years and is dedicated to bringing together scientists in the fields of meteoritics, astrophysics, planetary science, extrasolar planets, and Earth sciences to discuss frontier research on topics of shared interest. The Gordon Conference is unique in that the main program consists of review talks by 22 invited speakers and 9 discussions leaders who will present their latest research and findings. Significant time is set aside in each session and throughout the week for extended, free-flowing discussion on the materials presented and issues of interest to the audience. In addition, all attendees are invited to present posters on their latest work throughout the week. This year’s meeting will cover topics including: cosmochemical and astrophysical constraints on the formation of protoplanetary disks; the chemical evolution of protoplanetary disks as revealed by ALMA and meteorites; constraining planet formation through telescopic observations of Solar System objects; and the physical and chemical properties of planetary building blocks and the implications for how the Earth was assembled. The list of speakers and discussion leaders is included below. Applications to attend the meeting can be submitted through the conference website at: http://www.grc.org/programs.aspx?year=2015&program=origins Intentions to contribute a poster can be declared at the same time. Applications will be reviewed and notices of acceptance sent out beginning in late February. Attendance is limited to 200 participants. We expect to be able to dedicate some funds to help support early career scientists. Any questions can be directed to the Chair (Fred Ciesla: fciesla@uchicago.edu) or Vice Chair (Ted Bergin: ebergin@umich.edu). *Origins of Solar Systems Topics and Invited Participants:* Chair: Fred Ciesla (University of Chicago) Vice Chair: Ted Bergin (University of Michigan) 1. *The Formation and Early Evolution of Protoplanetary Disks: Processes and Settings* (*Lynne Hillenbrand* / Martin Bizzarro / Lee Hartmann) 2. *The Chemical Evolution of Protoplanetary Disk Materials* (*Geoffrey Blake* / Larry Nittler / Ilaria Pascucci / Ewine Van Dishoeck) 3. *Pebbles in Protoplanetary Disks* (*Andrea Isella* / Cornelius Dullemond / Hal Levison) 4. *Planet Migration and Its Collateral Effects* (*Rebekah Dawson* / Francesca DeMeo / Richard Nelson / Kevin Walsh) 5. *The Nature of Planetesimals and Their Evolution* (*Adrian Brearley* / Julie Castillo-Rogez / Thorsten Kleine) 6. *Exoplanetary Systems: A Diversity of Outcomes for Planet Formation* (*Eliza Kempton* / Jayne Birkby / Eric Ford / Nikku Madhusudhan) 7. *Debris Disks and Their Connection to Planet Formation* (*Aki Roberge* / Meredith Hughes / Brenda Matthews) 8. *The Geophysics and Geochemistry of Planetary Assembly* (*Stephen Mojzsis* / Richard Carlson / Tim Elliott / Sarah Stewart) 9. *Outer Solar System Record of Planet Formation* (*Anita Cochran* / David Minton / Scott Sheppard) -- Fred Ciesla Department of the Geophysical Sciences University of Chicago 5734 South Ellis Avenue Chicago, IL 60637 V: (773) 702-8169 F: (773) 702-9505 --
