Variable Stars in Clusters Group

This group has been involved in observing and/or modeling the light curves of variable stars in open and globular clusters. The idea is that variable stars are useful standard candles, the luminosities of which are obtainable from observational properties. On the other hand, when these objects are in well-studied star clusters, their age can be determined, thus the study of variables in clusters is a boot-strapping operation providing progress in our understanding of both variable stars and clusters. Members of our collaborative group have included:

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:

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:

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:
