Sub-surface structural changes associated with successive 11-yr solar activity cycles have been progressively more confined near the surface: new helioseismic results on Cycles 22 -- 25 from BiSON
William J. Chaplin, Sarbani Basu, Rachel Howe +3
We use Sun-as-a-star helioseismology data, collected by the Birmingham Solar-Oscillations Network (BiSON), to examine the relationship between the solar-cycle-induced frequency shi…

The seismic diversity of four successive solar cycle minima as observed by the Birmingham Solar-Oscillations Network (BiSON)
Sarbani Basu, William J. Chaplin, Rachel Howe +3
We have used data collected by the Birmingham Solar-Oscillations Network (BiSON) to perform a helioseismic diagnosis of changes to the Sun's internal structure between four success…

Farside helioseismology with Sun-as-a-star data: the solar cycle as seen with 7-day-long BiSON timeseries
R. Howe, W. J. Chaplin, Y. P. Elsworth +3
We present results from fitting -mode spectra derived from 7-d segments of Sun-as-a-star helioseismic observations from the Birmingham Solar Oscillations Network covering 32 yr.…
