Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. III. Constraints from a subgiant
K. Brogaard, F. Grundahl, E. L. Sandquist +18
Models of stellar structure and evolution can be constrained using accurate measurements of the parameters of eclipsing binary members of open clusters. Multiple binary stars provi…
Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. II. age dependencies and new insights
K. Brogaard, D. A. VandenBerg, H. Bruntt +11
Models of stellar structure and evolution can be constrained by measuring accurate parameters of detached eclipsing binaries in open clusters. Multiple binary stars provide the mea…
Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. I. Measurements, methods, and first results
K. Brogaard, H. Bruntt, F. Grundahl +4
Earlier measurements of the masses and radii of the detached eclipsing binary V20 in the open cluster NGC 6791 were accurate enough to demonstrate that there are significant differ…
