We use the recent results on solar acoustic modes coming from GOLF and MDI, to demonstrate that we improve the quality of the inversion of the sound speed and...

Aims: This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter mission (SO/PHI), the first magnetograph and helioseismology instrument...

Aims: We looked for signatures of quasi-biennial periodicity (QBP) over different phases of solar cycle by means of acoustic modes of oscillation. Low-degree p...

From the analysis of low-order GOLF+MDI sectoral modes (l

The solar p-mode spectrum of very low l has already been measured with high accuracy for a sufficiently long period of time to permit the search for solar cycle...

The characteristics of the three different principal data sets that have been extensively analyzed in a search for g-modes (Tenerife, ACRIM, and Stanford) are...

The site of the solar spectrometer of the International Research on the Interior of the Sun (IRIS) network, installed in December 1989 in the Teide Observatory...

We use two-dimensional numerical simulations and eikonal approximation to study properties of magnetohydrodynamic (MHD) waves traveling below the solar surface...
