Welcome to Bill Jefferys’ Home Page


I am Harlan J. Smith Centennial Professor of Astronomy (Emeritus) at the University of Texas at Austin, and former chairman of the U.T. Department of Astronomy. I am also an Adjunct Professor of Statistics at the University of Vermont. The Astronomy Department of the University of Texas hosted a retirement party for me, "Priors, Quaternions, and Residuals, Oh My".

Here are some Selected Papers.

Here is a link to my Atlas of Surfaces of Section for the Restricted Problem of Three Bodies, which was out of print but is now available on the web.

I was the Principal Investigator for the Hubble Space Telescope Astrometry Science Team. The Astrometry Science Team advised NASA on developing the HST Fine Guidance Sensors as astronomical instruments, and since launch has used them in scientific investigations.

To learn more about Harlan Smith, click here. To see the brochure that U.T. issued to inaugurate the Smith Professorship, click here. The brochure was put out a long time ago, so it is dated (my beard is gray, and my kids are grown up...see picture above). It describes what we planned to do with the Hubble at that time (before the Challenger disaster and before major changes in the HST program). It also includes some personal information about Harlan Smith.

A number of folks have asked about our farm in Fayston,Vermont, to which Sue and I have retired. I have put up some pictures for your enjoyment. 

Here is a link to the 1995 New York Howlerfest Home Page. The Howlerfest took place on July 28, 1995 at the Museum of Natural History in New York. See the professors of the University of Ediacara! See the action at the Panda's Thumb!
