Focus Meeting 7

Stellar Physics in Galaxies throughout the Universe
August 12 - 14, 2015

A 3-day Focus Meeting entitled "Stellar Physics in Galaxies throughout the Universe" will be held during the IAU XXIX General Assembly. The meeting will bring together astronomers from the stellar physics, extragalactic astrophysics and cosmology communities to discuss how current and future results can foster progress in these disjoint science areas. Areas covered include stellar evolution of single and binary stars from the zero-age main-sequence to the terminal stage, the feedback of stars to the interstellar medium via radiation, dust production and chemical enrichment, and the properties of the most massive stars and of cosmologically significant stellar phases such as AGB and Wolf-Rayet stars. We will evaluate the limitations of our understanding of the physics of local stars and their effects on, e.g., ages, chemical composition and the initial mass function of galaxies at low to high redshift. The meeting is timely because of new results from recently commissioned telescopes and because of the prospects from future 30-m class telescopes.

Major topics:
  • single and binary-star evolution
  • stellar rotation and its impact on stellar evolution
  • stellar yields and the metallicity evolution versus redshift
  • release of ionizing radiation and chemical elements into the ISM
  • stellar evolutionary phases and their signatures in galaxy SED's
  • age-dating of galaxies over cosmic time
