Dear colleagues,

Due to power cuts in two consecutive nights (May 30 and 31) for maintenance purpose, the IAUS323 web server was not functioning properly, though the actual registration system is running on a different server linked to the IAUS323 website. As a result, some of you might experience difficulties when submitting abstracts for oral contributions. As such, we have decided to postpone the deadline of abstract submission and grant application to midnight Beijing time (UTC + 8 hr) of Tuesday June the 7th.

Those who have submitted an abstract successfully shall receive a confirmation email within 24hr. If you don't, pls contact Ms. Dandan Bai at oec238i@pku.edu.cn. Similarly, for grant application, those who have submitted successfully will receive a confirmation email. If you don't, pls contact Ms. Ning Zhang at zhangn@pku.edu.cn

We apologize for the inconvenience.

NB: The aforementioned abstract submission deadline is for soliciting oral CONTRIBUTIONS only. Abstracts of the INVITED talks will be requested at a later time. The SOC shall email you in due course whether your proposed oral contribution(s) have been allocated time or not.

Planetary nebulae are the spectacular products of low- and intermediate-mass stellar evolution. Understanding their formation and origin is key to understanding fundamental yet highly uncertain physics of single and binary star evolution. The shapes and spectral characteristics of PNe are unique and visible out to great distance. For a long time, the use of PNe as effective probes of stellar populations and galactic dynamics has been very successful. The current symposium is a continuation of a 5year cycle of PN IAU Symposia proposed and organized by the IAU PN WG, based on a continuing stream of interest for this fascinating subject, with connections to stellar evolution, gas and dust chemistry and recycling, stellar population in the Milky Way, in the Local group, and in external galaxies as well.

  - New challenges to surveys of PNe in the Local Group
  - PNe as a versatile laboratory of dust and molecular studies
  - From the asymptotic giant branch to the white dwarf stellar phases
  - The connection between binary evolution and the PN phenomena
  - PNe as probes of galactic chemical evolution and dynamics
  - PNe outside of the local group
  - PNe and forefront instrumentation

We expect to see a broad participation to this symposium!
