First performances of the GOLF-NG instrumental prototype observing the Sun in Tenerife
D. Salabert, S. Turck-Chieze, J. C. Barriere +14
The primary challenge of GOLF-NG (Global Oscillations at Low Frequency New Generation) is the detection of the low-frequency solar gravity and acoustic modes, as well as the possib…
Low-frequency solar p modes as seen by GOLF and GONG instruments
D. Salabert, R. A. Garcia
In the case of spatially-revolved helioseismic data (such as MDI, GONG, HMI), the usual mode-fitting analysis consists of fitting the 2l+1 individual m-spectra of a given multiplet…
What can we learn on the structure and the dynamics of the solar core with g modes?
S. Mathur, J. Ballot, A Eff-Darwich +4
The detection of the signature of dipole gravity modes has opened the path to study the solar inner radiative zone. Indeed, g modes should be the best probes to infer the propertie…
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…
GOLF: a new proxy for solar magnetism
S. Mathur, S. J. Jimenez-Reyes, R. A. Garcia
Solar magnetism is measured with different indexes: for instance the MPSI and the MWSI, number of sunspots, radio flux at 10.7 cm, Ca II K, Mg II K, EUV, He I or L_alpha. Bachmann…
Spatial Cross Spectrum: Reducing Incoherent Convective Background of Resolved Heloseismic Instruments
R. A. Garcia, S. Mathur, I. Gonzalez Hernandez +1
Measurements of low-order p modes and gravity modes are perturbed by the solar convective background. Such perturbation increases below 2mHz for intensity measurements and 1mHz for…
