Rotation of the solar interior
J. Christensen-Dalsgaard, M. J. Thompson
Helioseismology has allowed us to infer the rotation in the greater part of the solar interior with high precision and resolution. The results show interesting conflicts with earli…
On Inverting Asteroseismic Data
M. J. Thompson, J. Christensen-Dalsgaard
Some issues of inverting asteroseismic frequency data are discussed, including the use of model calibration and linearized inversion. An illustrative inversion of artificial data f…
SOLA inversions for the core structure of solar-type stars
Sarbani Basu, J. Christensen-Dalsgaard, M. J. Thompson
The Subtractive Optimally Localized Averages (SOLA) method, developed and extensively used in helioseismology, is applied to artificial data to obtain measures of the sound speed i…
Asteroseismic Inference for Solar-Type Stars
M. J. P. F. G. Monteiro, J. Christensen-Dalsgaard, M. J. Thompson
The oscillation spectra of solar-type stars may in the not-too- distant future be used to constrain certain properties of the stars. The CD diagram of large versus small frequency…
