Variation in p-mode power over solar cycle 23 as seen from BiSON and GOLF observations
R. Simoniello, D. Salabert, R. A. Garcia
We analyzed BiSON and GOLF/SoHO data with a new technique, to investigate p-mode power variation over solar cycle 23. We found a decrease in the mean velocity power of about 20% fo…
Variations of the solar granulation motions with height using the GOLF/SoHO experiment
S. Lefebvre, R. A. Garcia, S. J. Jimenez-Reyes +2
Below 1 mHz, the power spectrum of helioseismic velocity measurements is dominated by the spectrum of convective motions (granulation and supergranulation) making it difficult to d…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
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…
