On the Evolution of Detached Algol Systems
Douglas S. Hall · Publications of the Astronomical Society of the Pacific · 1968
Roxburgh (1966) has advanced the hypothesis that close binary systems with undersize subgiants (referred to in this note as detached Algol systems) are in the pre-main-sequence evolutionary phase.When he applied this hypothesis to K0 Aquilae, which is a prototype, he derived an age of 10 6 years.If the same procedure is
