Gonzales Returns to SAS Meeting for Another Great Lecture

By George Best
May Meeting

Guillermo Gonzales
Research Assistant Professor
University of Washington
Department of Astronomy
Wednesday, May 16
7:30 p.m.

A-102 Physics-Astronomy Bldg.
University of Washington

Come early at 7 p.m. to visit with your fellow members.

Bring your slides for after the program.

OUR speaker for the May 16 meeting of the Seattle Astronomical Society (SAS) will be Guillermo Gonzales, Research Assistant Professor at the University of Washington. Guillermo has spoken at SAS meetings several times on such topics as extra-solar planets, stellar evolution, eclipses, and non-terrestrial life in the universe.

The topic of his lecture for this month's meeting is "Mining the Earth's Attic for signs of Ealy Earth Life". If it's anything like his past talks, we're in for a treat.

Guillermo is the expert on planets outside our solar system, and is primarily interested in late stage stellar evolution through the use of spectroscopic observations. Recent work includes spectroscopic abundances, analysis of post-AGB supergiants and RV Tau variables. He has also undertaken the study of parent states of the recently discovered extra-solar planetary systems. The results indicate that these stars have anomalous chemical abundances suggesting the same sort of formation history.

The May 16 meeting will be held in the Physics-Astronomy Building on the University of Washington campus, Seattle.
