In addition, it is a pleasure to acknowledge the invaluable assistance of
Graham Hill, Peter Stetson, Murray Fletcher, Wes Fisher, Daniel Durand,
Gerry Justice, Steven Morris, and others of the DAO staff over the years.
We also owe a debt of gratitude to our colleagues at San Diego State University
(esp., Ron Angione, Director, Paul Etzel and Bob Leech) for supporting several
observing trips to Mt. Laguna. Mr. Grant Miller also helped to obtain
direct images on the Mt. Laguna 1-m telescope.
Eclipsing Binary Modeling Group
This group is involved with the improvement of eclipsing binary modeling tools.
The group arose out of a collaboration to upgrade and improve the
WIlson-Devinney as per suggestions I made at the 1985 Beijing Meeting (the first
Pacific-Rim Conference on New Frontiers in Binary Stars Research), at the
the Korea meeting (second Pacific Rim Conference) in 1990, at the
modeling conference in Buenos Aires & Cordoba in 1991, at the Third Pacific Rim
Conference on Binary Star Research in Chiang Mai, Thailand in 1995, and at the
AAS topical meeting on New Developments in Eclipsing Binary Light Curve
Modeling meeting in 1997.
The group consists of:
- Josef Kallrath, BASF & Univ. of Bonn, Univ. of Heidelberg [simplex;
atmospheric eclipses; WD95, WD98 coding; analyses]
- Jason McVean, Univ. of Calgary [neural net algorithms]
- Gene Milone, Univ. of Calgary [planning; observations; analyses]
- Chris Stagg, Mt. Royal College, Calgary [programming; analyses]
- Dirk Terrell, SouthWest Research Institute [programming; codeing; analyses]
- Mike Williams, Univ. of Calgary [programming; analyses]
- Andy Young, San Diego State Univ. [planning; programming; analyses]
with much appreciated assistance from
- Walter van Hamme, Florida International University
- Horst Drechsel, Bamberg, FRG
- Doug Philips, Univ. of Calgary.
we acknowledge Bob Wilson and Ed Devinney for providing the Wilson-Devinney
program to the community, and Bob especailly, for maintaining and developing it
further over more than three decades.
In the past few years, I have been a member of a group organized by Prof.
Ulisse Munari of Asiago Observatory, University of Padua, to check out
the capability of the GAIA satellite to provide fundamental data from
eclipsing binary star observations. This cornerstone mission of the European
Space Agency promises to revolutionize our understanding of galactic
kinematics and structure.
In addition, over the past decade, pulsating stars have been studied at the Univ. of Calgary.
The scientists involved in this modeling work have been:
- Gene Milone
- Kevin Volk
- Bill Wilson
- Virginia Volk
- Joe Postma
Infrared Extinction & Standardization
This group is in fact an IAU Working Group formed in Comm, 25 to try
to improve the infrared photometry in astronomy. The background to this
project can be found in Infrared extinction and Standardization,
'Lecture Notes in Physics' No. 341, (Berlin: Springer-Verlag), 1989.
A new set of infrared passbands better centered in the atmospheric windows
has been derived after extensive numerical experimentation. Details of
the work can be found in Young et al., A&AS, 105 259-279, 1994.
The participants of this extensive group have included:
