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…

Asteroseismology with PBjam 2.0: measuring dipole mode frequencies in coupling regimes from main sequence to low-luminosity red giant stars
M. B. Nielsen, J. M. J. Ong, E. J. Hatt +7
PBjam is an open-source software package for measuring mode frequencies of solar-like oscillators. These frequencies help constrain stellar evolution models to precisely estimate m…

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.…
