Asteroseismic sensitivity to internal rotation along the red-giant branch
F. Ahlborn, E. P. Bellinger, S. Hekker +2
Transport of angular momentum in stellar interiors is currently not well understood. Asteroseismology can provide us with estimates of internal rotation of stars and thereby advanc…
The Aarhus red giants challenge II. Stellar oscillations in the red giant branch phase
J. Christensen-Dalsgaard, V. Silva Aguirre, S. Cassisi +23
Context. The large quantity of high-quality asteroseismic data that obtained from space-based photometric missions and the accuracy of the resulting frequencies motivate a careful…
The Aarhus Red Giants Challenge I: Stellar structures in the red giant branch phase
V. Silva Aguirre, J. Christensen-Dalsgaard, S. Cassisi +23
(Abridged). We introduce the Aarhus Red Giants Challenge, a series of detailed comparisons between widely used stellar evolution and oscillation codes aiming at establishing the mi…
Asteroseismology of KIC 8263801:Is it a member of NGC 6866 and a red clump star?
Yanke Tang, Sarbani Basu, Guy R. Davies +2
We present an asteroseismic analysis of the Kepler light curve of KIC 8263801, a red-giant star in the open cluster NGC 6866 that has previously been reported to be a helium-burnin…
