Subject: IAU Division G newsletter for fall 2018 V2

We send our deepest apologies for the accidental use of the wrong gender pronoun in our previous newsletter. Please refer to the following corrected newsletter for important messages from your Division G colleagues.

IAU Division G, Stars and Stellar Physics, Quarterly Newsletter

What is this?

As president of IAU’s Division G, I intend to send division members a brief e-mail regularly with relevant IAU news. Your comments are welcome.

Nominate an outstanding student for an IAU PhD prize

Two years ago the IAU started a new effort to recognize outstanding PhD theses. Each IAU division can name one recipient of the PhD prize every year. In addition to the recognition, winners receive travel support to attend the next General Assembly. Division G in the past has received many truly excellent applications, making the final decision difficult. IAU members should, however, make sure their PhD students know about this opportunity so they can apply. Watch for an announcement from the IAU.

Join the IAU as a Junior Member

The IAU just this year approved the new membership category of Junior Member. Junior membership is for individuals who are within 6 years of completing their PhDs. Junior membership is temporary and expires after 6 years; a Junior Member is expected to apply for Individual Membership within that time.

Applications will be due December 31, 2018. Please bring this opportunity to the attention of recent PhDs! More information is at:

IAU news

IAU100 celebrates the union’s centennial. As part of that there will be a day devoted to women and girls in astronomy. Learn more at:

I regret to have to pass on sad news about the passing of two Division G members: Zbigniew Kolaczkowski (deceased 2018-09-22) and John Graham (deceased 2018-09-13). See and

News for stellar astronomers

  • The astronomical community has accumulated a significant amount of historical records of observations of the Sun, stars and other astronomical objects. Those records contain irreplaceable information about long-term evolutionary and non-evolutionary changes in our Universe, and clearly need to be preserved so that researchers can access and exploit them. As a first step in that process, we are creating an inventory of historical data which members of the astronomical community consider to be worthy of preservation. Most such records are analogue ones (plates, film, paper, books) but can include primitive magnetic tapes (e.g., those lacking recognizable formatting) or other early digital data. We solicit input from the community as to which data exist that you feel merit consideration for preservation, the current state of those data (e.g., digitized or not) or of any associated metadata, and their current location. You can provide your input via this web form: Please share this invitation with colleagues who may be able to contribute to our inventory and who for whatever reason may not receive it through the IAU mailing. For more information, contact Alexei Pevtsov (
  • HST will devote 600-1000 orbits of Director's Discretionary time to a Hubble Ultraviolet Legacy Initiative focused on star formation and associated stellar astrophysics. A Working Group has been constituted to engage with the scientific community and make recommendations to the Director on the form of the eventual program. As part of that process, the Working Group is soliciting input from the community via a short survey: Please provide responses by December 7, 2018. The UV Legacy Working Group is chaired by Sally Oey (U. Michigan), with members Nate Bastian (Liverpool), Paul Crowther (Sheffield), Andrew Fox (STScI), Jay Gallagher (Wisconsin), Ana Gomez de Castro (Madrid), Claus Leitherer (STScI), Christy Tremonti (Wisconsin).

  • Appropriate scientific or review papers are invited for a special topical issue of Advances in Space Research (ASR) entitled “Nova Eruptions, Cataclysmic Variables and related systems: Observational vs. theoretical challenges in the 2020 era.” This special issue is open to all scientists and collaborations. Papers must be submitted electronically to Authors must select “Special Issue:- Novae, CVs & Related Sys” when they reach the "Article Type” step in the submission process which starts after December 1, 2018. Prof. Dr. Şölen Balman ( is the Guest Editor for this special issue. Questions can be directed to Prof. Balman (her) or to the Co-Editor for Special Issues, Dr. Peggy Ann Shea (
  • Werner Weiss in Vienna has organized a conference on “Stars and their Variability - Observed from Space”: The motivation is to convene top scientists and to discuss open issues in stellar modeling due to discrepancies between theory and related aspects of observations from space, including the physics needed to describe their structure (convection, rotation, magnetic fields, etc.) and evolution (from genesis to end of life), considering the interaction with their environment (winds out and in, outbursts, magnetic fields, etc.), and being member of ensembles (from binaries to galaxies).
  • Dr. C. Popescu (, on behalf of the Inter-Division Commission J1 (The spectral energy distributions of galaxies), wants to encourage Division G members to join Commission J1 (by contacting her). More information on J1 can be found at: Please also contact her if you are involved in an IAU symposium proposal that is of relevance.
