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…

Constraints on sunspot group lifetimes from far-side Sun-as-a-star helioseismology with BiSON

William J. Chaplin, Rachel Howe, Sarbani Basu +5

Frequencies of low-degree solar p modes are sensitive to activity over the entire Sun, including the unobservable far-side hemisphere. When frequency shifts extracted from week-lon…

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.…

Low-degree solar rotational splitting from 45 years of BiSON observations

Rachel Howe, W. J. Chaplin, Y. P. Elsworth +2

We present solar low-degree rotational splitting values based on a new analysis of Sun-as-a-star observations from the Birmingham Solar Oscillations Network, covering a 16,425-day…

Unexpected solar-cycle variation of acoustic mode power in Sun-as-a-star observations

Rachel Howe, W. J. Chaplin, Y. P. Elsworth +2

We examine the solar-cycle variation of the power in the low-degree helioseismic modes by looking at binned power spectra from 45 years of observations with the Birmingham Solar Os…
