Absolute Properties of the Eclipsing Binary Star V501 Herculis
Claud H. Sandberg Lacy, Francis C. Fekel
V501 Her is a well detached G3 eclipsing binary star with a period of 8.597687 days for which we have determined very accurate light and radial-velocity curves by using robotic tel…

Claud H. Sandberg Lacy, Guillermo Torres, Francis C. Fekel +1
AP And is a well-detached F5 eclipsing binary star for which only a very limited amount of information was available before this publication. We have obtained very extensive measur…
The Spectroscopic Orbits of Five Solar Type, Single Lined Binaries
Francis C. Fekel, Samira Rajabi, Matthew W. Muterspaugh +1
We have determined spectroscopic orbits for five single-lined spectroscopic binaries, HD 100167, HD 135991, HD 140667, HD 158222, HD 217924. Their periods range from 60.6 to 2403 d…
