Effect of asymmetry in peak profiles on solar oscillation frequencies
Sarbani Basu, H. M. Antia
Most helioseismic analyses are based on solar oscillations frequencies obtained by fitting symmetric peak profiles to the power spectra. However, it has now been demonstrated that…
How much do helioseismological inferences depend upon the assumed reference model?
Sarbani Basu, M. H. Pinsonneault, John N. Bahcall
We investigate systematic uncertainties in determining the profiles of the solar sound speed, density, and adiabatic index by helioseismological techniques. We find that rms uncert…
Large scale flows in the solar interior: Effect of asymmetry in peak profiles
Sarbani Basu, H. M. Antia
Ring diagram analysis can be used to study large scale velocity fields in the outer part of the solar convection zone. All previous works assume that the peak profiles in the solar…
On the choice of parameters in solar structure inversion
M. C. Rabello-Soares, Sarbani Basu, J. Christensen-Dalsgaard
The observed solar p-mode frequencies provide a powerful diagnostic of the internal structure of the Sun and permit us to test in considerable detail the physics used in the theory…
