Nancy Houk

Nancy Houk (born abt. 1940)^[1] is an American astronomer who taught at the University of Michigan and has published numerous books and articles on astronomy. Houk led the decades-long effort to establish a comprehensive database of stellar temperatures and luminosities.^[2][3]

Education

Houk obtained a bachelor of science degree from the University of Michigan where she researched at the Maria Mitchell Observatory, named for America's first woman professional astronomer.

Houk earned her doctorate in astronomy from Case Western Reserve University in 1967. She also carried out postdoctorate studies at Case Western,^[3] and the Kapteyn Laboratory in the Netherlands.

Career

Houk joined the Astronomy Department of the University of Michigan in 1970 as a research associate.^[4] This was followed by promotions to research associate in 1973, associate research scientist in 1977, then research scientist in 1985.

From 1971,^[5] Houk led the effort to establish a comprehensive database of stellar temperatures and luminosities.^[3][6] By 2014, the project had assembled five volumes, covering the sky from the south celestial pole to +5° declination, consisting of 162,900 stars in total.^[7]

The images taken provide information about the physical properties of stars such as their composition of atomic elements and molecules, mass, temperature, rotational properties, age, distance, spectra classification and more. Houk used this data to construct the fundamental diagram used in astrophysics called the Hertzsprung-Russell Diagram that forms the basis of modern astrophysics.^[8]

Houk was the editor of the Michigan Spectral Catalog.^[3] Her work was supported by funding from the National Science Foundation.^[3]

Collections

Houk retired in 2001 and donated half of her plate collection, which surveyed the entire southern hemisphere night sky, to the Astronomical Photographic Data Archive (APDA) in 2004.^[9]

The other half of her collection resides in Japan. APDA, located at the Pisgah Astronomical Research Institute, where there are plans to digitize her photographic plates.^[10]

Nancy Houk transferring her collection to APDA. Standing next to her is Michael Castelaz, PARI Research Director in 2004 who accepted Nancy Houk's collection on behalf of APDA.

Publications

Houk's research is published in 5 volumes of the Michigan Spectral Catalog where the first set of HR diagrams are presented from her data.

Publications resulting from her research are listed below:
