Measuring Solar Abundances with Seismology

The revision of the photospheric abundances proferred by Asplund et al has rendered opacity theory inconsistent with the seismologically determined opacity through the Sun. This highlights the need for a direct seismological measurement of solar abundances. Here we describe the technique used to measure abundances with seismology, examine our ability to detect differences between solar models u...

Solar Flare Cycles

We present a review of different solar flare periodicity intervals. Our analysis includes a statistical investigation of flare occurrence and N-S hemispheric distribution over the last three 11-yr solar cycles (SCs 21-23, corresponding to the period 1976-2001). Moreover, we try to estimate if there is any connection between the flare activity and the strength of solar cycles. For that purpose, ...

SOLAR SEISMOLOGY. I. THE STABILITY OF THE SOLAR p-MODES*

We investi~ate the s~ability of the radialp-modes of the Sun by computing nonadiabatic eigenvalues and e1genfunc~ons for a solar envelope model which extends from an inner radius r ~ 0.3 J!..e out to an optical depth -r ~ 3 x I04 • Our calculations take into account in a crude fashion the re~ponse of.the convec?ve ~ux to the oscillation. The dynamical effect of turbulence m the convection zone ...
