Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752

Eric L. Sandquist, Andrew J. Buckner, Matthew D. Shetrone +8

We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 day binary DS An…

Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. II. Revised stellar masses and radii for KIC 8430105

Jeppe Sinkbæk Thomsen, Karsten Brogaard, Torben Arentoft +6

Asteroseismic scaling relations can provide high-precision measurements of mass and radius for red giant (RG) stars displaying solar-like oscillations. Their accuracy can be valida…

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…

Extremely precise age and metallicity of the open cluster NGC 2506 using detached eclipsing binaries

E. Knudstrup, F. Grundahl, K. Brogaard +10

Accurate stellar parameters of stars in open clusters can help constrain models of stellar structure and evolution. Here we wish to determine the age and metallicity content of the…

Asteroseismology of the Hyades red giant and planet host epsilon Tauri

Torben Arentoft, Frank Grundahl, Timothy R. White +23

Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods. Even in a well-s…

Hardware and software for a robotic network of telescopes - SONG

M. F. Andersen, F. Grundahl, J. Christensen-Dalsgaard +7

SONG aims at setting up a network of small 1m telescopes around the globe to observe stars uninterrupted throughout days, weeks and even months. This paper describes the fundamenta…
