Precise radial velocities of giant stars -- XVII. Distinguishing planets from intrinsically induced radial velocity signals in evolved stars
Dane Spaeth, Sabine Reffert, Trifon Trifonov +6
From a long-term Doppler monitoring campaign of 373 giant stars, we have identified ten giants with periodic radial velocity variations that are challenging to associate with plane…
Atmospheric parameters and abundances of cool red giant stars
Z. Dencs, A. Derekas, T. Mitnyan +10
Understanding the atmospheric parameters of stars on the top of the RGB is essential to reveal the chemical composition of the Milky Way, as they can be used to probe the farthest…
Doppler imaging and differential rotation of Coronae Borealis using SONG
Yue Xiang, Shenghong Gu, A. Collier Cameron +6
We present new Doppler images of both components of the double-lined binary CrB, based on the high-resolution spectroscopic data collected during 11 nights in 2015 March--A…
The BRITE-SONG of Aldebaran -- Stellar Music in three voices
P. G. Beck, R. Kuschnig, G. Houdek +20
Solar-like oscillations in red-giant stars are now commonly detected in thousands of stars with space telescopes such as the NASA Kepler mission. Parallel radial velocity and photo…
The acoustic cut-off frequency of the Sun and the solar magnetic activity cycle
A. Jimenez, R. A. Garcia, P. L. Palle
The acoustic cut-off frequency -the highest frequency for acoustic solar eigenmodes- is an important parameter of the solar atmosphere as it determines the upper boundary of the p-…
New insights on the solar core
R. A. Garcia, D. Salabert, J. Ballot +11
Since the detection of the asymptotic properties of the dipole gravity modes in the Sun, the quest to find individual gravity modes has continued. An extensive and deeper analysis…
Detecting individual gravity modes in the Sun: Chimera or reality?
Rafael A. Garcia, J. Ballot, A. Eff-Darwich +11
Over the past 15 years, our knowledge of the interior of the Sun has tremendously progressed by the use of helioseismic measurements. However, to go further in our understanding of…
Detecting individual gravity modes in the Sun
R. A. Garcia, J. Ballot, A. Eff-Darwich +9
Many questions are still open regarding the structure and the dynamics of the solar core. By constraining more this region in the solar evolution models, we can reduce the incertit…
Detection of periodic signatures in the solar power spectrum. On the track of l=1 gravity modes
R. A. Garcia, S. Turck-Chieze, S. J. Jimenez-Reyes +5
In the present work we show robust indications of the existence of g modes in the Sun using 10 years of GOLF data. The present analysis is based on the exploitation of the collecti…
