Impact of a radius and composition variation on the solar subsurface layers stratification
Sandrine Lefebvre, Phu Anh Phi Nghiem, Sylvaine Turck-Chieze
Several works have reported changes of the Sun's subsurface stratification inferred from f-mode or p-mode observations. Recently a non-homologous variation of the subsurface layers…
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…
Solar Mean Magnetic Field Near the Surface and its Variation During a Cycle
P. A. P. Nghiem, R. A. Garcia, S. J. Jimenez-Reyes
The unsigned mean magnetic field characterizes the magnetic energy settled in the region near the solar surface. It is one of the determinant ingredients that govern the turbulence…
Procyon-A and Eta-Bootis: Observational Frequencies Analyzed by the Local-Wave Formalism
P. A. P. Nghiem, J. Ballot, R. A. Garcia +2
In the present analysis of Procyon-A and Eta-Bootis, we use the local-wave formalism which, despite its lack of precision inherent to any semi-analytical method, uses directly the…
Description of Stellar Acoustic Modes Using the Local Wave Concept
P. A. P. Nghiem
An understanding of stellar acoustic oscillations is attempted, using the local wave concept in semi-analytical calculations. The local homogeneity approximation allows to obtain s…
The magnetism of the solar interior for a complete MHD solar vision
S. Turck-Chieze, T. Appourchaux, J. Ballot +37
The solar magnetism is no more considered as a purely superficial phenomenon. The SoHO community has shown that the length of the solar cycle depends on the transition region betwe…
Surprising Sun
S. Turck-Chieze, S. Couvidat, L. Piau +5
Important revisions of the solar model ingredients appear after 35 years of intense work which have led to an excellent agreement between solar models and solar neutrino detections…
