Inversions of stellar structure from asteroseismic data
Gaël Buldgen, Jérôme Bétrisey, Ian W. Roxburgh +2
The advent of space-based photometry missions in the early 21st century enabled the application to asteroseismic data of advanced inference techniques until then restricted to the…
Recent Developments in Helioseismic Analysis Methods and Solar Data Assimilation
Ariane Schad, Laurene Jouve, Tom L. Duvall +2
We review recent advances and results in enhancing and developing helioseismic analysis methods and in solar data assimilation. In the first part of this paper we will focus on sel…
Helioseismic Measurements in the Solar Envelope Using Group Velocities of Surface Waves
S. V. Vorontsov, V. A. Baturin, S. V. Ayukov +1
At intermediate and high degree , solar p- and f modes can be considered as surface waves. Using variational principle, we derive an integral expression for the group velocities…
Modelling Solar Oscillation Power Spectra: II. Parametric Model of Spectral Lines Observed in Doppler Velocity Measurements
Sergei V. Vorontsov, Stuart M. Jefferies
We describe a global parametric model for the observed power spectra of solar oscillations of intermediate and low degree. A physically motivated parameterization is used as a subs…
On the use of the ratio of small to large separations in asteroseismic model fitting
Ian W Roxburgh, Sergei V Vorontsov
Context. The use of ratios of small to large separations as a diagnostic of stellar interiors. Aims. To demonstrate that model fitting by comparing observed and model separation ra…
Solar Cycle Variation of the Solar Internal Rotation: Helioseismic Inversion and Dynamo Modelling
S. Vorontsov, R. Tavakol, E. Covas +1
We report our first results on comparing the variations of the solar internal rotation with solar activity, as predicted by non-linear solar dynamo modelling, with helioseismic mea…
