Low-amplitude solar-like oscillations in the K5 V star Indi A
Mia S. Lundkvist, Hans Kjeldsen, Timothy R. Bedding +17
We have detected solar-like oscillations in the mid K-dwarf Indi A, making it the coolest dwarf to have measured oscillations. The star is noteworthy for harboring a…
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…
Chromospheric emission of solar-type stars with asteroseismic ages
R S Booth, K. Poppenhaeger, C. A. Watson +3
Stellar magnetic activity decays over the main-sequence life of cool stars due to the stellar spin-down driven by magnetic braking. The evolution of chromospheric emission is well-…
The blue straggler V106 in NGC6791: A prototype progenitor of old single giants masquerading as young
K. Brogaard, S. M. Christiansen, F. Grundahl +18
We determine the properties of the binary star V106 in the old open cluster NGC6791. We identify the system to be a blue straggler cluster member by using a combination of ground-b…
Establishing the accuracy of asteroseismic mass and radius estimates of giant stars. I. Three eclipsing systems at [Fe/H]~ -0.3 and the need for a large high-precision sample
K. Brogaard, C. J. Hansen, A. Miglio +12
We aim to establish and improve the accuracy level of asteroseismic estimates of mass, radius, and age of giant stars. This can be achieved by measuring independent, accurate, and…
