Solar abundances and helioseismology: fine structure spacings and separation ratios of low-degree p modes
نویسندگان
چکیده
We have used 4752 days of data collected by the Birmingham SolarOscillations Network (BiSON) to determine very precise oscillation frequencies of acoustic low-degree modes that probe the solar core. We compare the fine (small frequency) spacings and frequency separation ratios formed from these data with those of different solar models. We find that models constructed with low metallicity are incompatible with the observations. The results provide strong support for lowering the theoretical uncertainties on the neutrino fluxes. These uncertainties had recently been raised due to the controversy over the solar abundances. Subject headings: Sun: helioseismology Sun: interior Sun: abundances neutrinos

Sensitivity of the low degree oscillations to the change of solar abundances
Context. The most recent determination of the solar chemical composition by Asplund et al. (2005), using time-dependent, 3D hydrodynamical model of the solar atmosphere, exhibits a significant decrease on C, N, O abundances compared to their previous values. Solar models that use these new abundances are not consistent with helioseismological determinations of the sound speed profile, the surfa...

متن کاملThe solar core: new low-l p-mode fine-spacing results from BiSON
The fine-structure spacing dl(n) = νl,n − νl+2,n−1 for low-degree solar p modes of angular degree l and radial order n is sensitive to conditions in the deep radiative interior of the Sun. Here we present fine-structure spacings derived from the analysis of nearly five years of helioseismological data collected between 1991 July and 1996 February by the Birmingham Solar-Oscillations Network (Bi...
متن کاملFresh Insights on the Structure of the Solar Core
We present new results on the structure of the solar core, obtained with new sets of frequencies of solar low-degree p modes obtained from the BiSON network. We find that different methods used in extracting the different sets of frequencies cause shifts in frequencies, but the shifts are not large enough to affect solar structure results. We find that the BiSON frequencies show that the solar ...
متن کاملOptimal Masks for Low-Degree Solar Acoustic Modes.
We suggest a solution to an important problem in observational helioseismology of the separation of lines of solar acoustic (p) modes of low angular degree in oscillation power spectra by constructing optimal masks for Doppler images of the Sun. Accurate measurements of oscillation frequencies of low-degree modes are essential for the determination of the structure and rotation of the solar cor...
