The inhomogeneous response across the solar disc of unresolved Doppler velocity observations
A. M. Broomhall, W. J. Chaplin, Y. Elsworth +1
Unresolved Doppler velocity measurements are not homogenous across the solar disc (Brookes et al. 1978). We consider one cause of the inhomogeneity that originates from the BiSON i…

Asteroseismology of Red Giant stars
N. J. Tarrant, W. J. Chaplin, Y. P. Elsworth +2
Sun-like oscillations, that is p-modes excited stochastically by convective noise, have now been observed in a number of Red Giant stars. Compared to those seen in the Sun, these m…

Are low-degree p mode frequencies predictable from one cycle to the next?
A. M. Broomhall, W. J. Chaplin, Y. Elsworth +2
The Birmingham Solar-Oscillations Network (BiSON) has been collecting data for over 30yrs and so observations span nearly three 11yr solar activity cycles. This allows us to addres…
