Variations of the mixing character of dipolar mixed modes in red giant stars
C. Jiang, M. Cunha, J. Christensen-Dalsgaard +1
Thanks to the high quality data of space missions, the detection of mixed modes has become possible in numerous stars. In this work, we investigate how the mixing character of dipo…
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…
The mass and age of the first SONG target: the red giant 46 LMi
S. Frandsen, M. Fredslund Andersen, K. Brogaard +12
The Stellar Observation Network Group (SONG) is an initiative to build a worldwide network of 1m telescopes with highprecision radial-velocity spectrographs. Here we analyse the fi…
Using the phase shift to asymptotically characterize the dipolar mixed modes in post-main-sequence stars
C. Jiang, J. Christensen-Dalsgaard, M. Cunha
Mixed modes have been extensively observed in post-main-sequence stars by the Kepler and CoRoT space missions. The mixture of the p and g modes can be measured by the dimensionless…
Metallicity effect on stellar granulation detected from oscillating red giants in open clusters
E. Corsaro, S. Mathur, R. A. García +9
The effect of metallicity on the granulation activity in stars is still poorly understood. Available spectroscopic parameters from the updated APOGEE-\textit{Kepler} catalog, coupl…
