GONG p-mode parameters through two solar cycles
René Kiefer, Rudi Komm, Frank Hill +2
We investigate the parameters of global solar p-mode oscillations, namely damping width , amplitude , mean squared velocity , energy , and energy suppl…
Seismic signatures of magnetic activity in solar-type stars observed by Kepler
A. R. G. Santos, T. L. Campante, W. J. Chaplin +8
The properties of the acoustic modes are sensitive to magnetic activity. The unprecedented long-term Kepler photometry, thus, allows stellar magnetic cycles to be studied through a…
Signatures of magnetic activity in the seismic data of solar-type stars observed by Kepler
A. R. G. Santos, T. L. Campante, W. J. Chaplin +8
In the Sun, the frequencies of the acoustic modes are observed to vary in phase with the magnetic activity level. These frequency variations are expected to be common in solar-type…
The Effect of Toroidal Magnetic Fields on Solar Oscillation Frequencies
René Kiefer, Markus Roth
Solar oscillation frequencies change with the level of magnetic activity. Localizing subsurface magnetic field concentrations in the Sun with helioseismology will help us to unders…
