Automation and Modernisation of Legacy BiSON Solar Observatories with the BiSON:NG Platform
S. J. Hale, E. Murray, W. J. Chaplin +4
The Birmingham Solar Oscillations Network (BiSON) provides long-term, high-precision Sun-as-a-star radial-velocity observations for helioseismology. While most BiSON sites operate…
Ensemble asteroseismology: An ensemble approach to detecting signatures of solar-like oscillations in K-dwarfs
William J. Chaplin, Tiago L. Campante, Mikkel N. Lund +5
Solar-like oscillations have to date been observed in hundreds of main-sequence and sub-giant stars. However, only a handful of detections have been made in K-type dwarfs, using gr…
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.…
