Excitation and damping of p-mode oscillations of alpha Cen B
W. J. Chaplin, G. Houdek, Y. Elsworth +3
This paper presents an analysis of observational data on the p-mode spectrum of the star alpha Cen B and a comparison with theoretical computations of the stochastic excitation and…
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…
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…
solarFLAG hare and hounds: estimation of p-mode frequencies from Sun-as-star helioseismology data
S. J. Jimenez-Reyes, W. J. Chaplin, R. A. Garcia +14
We report on the results of the latest solarFLAG hare-and-hounds exercise, which was concerned with testing methods for extraction of frequencies of low-degree solar p modes from d…
Challenges for asteroseismic analysis of Sun-like stars
W. J. Chaplin, G. Houdek, T. Appourchaux +3
Asteroseismology of Sun-like stars is undergoing rapid expansion with, for example, new data from the CoRoT mission and continuation of ground-based campaigns. There is also the ex…
AsteroFLAG: first results from hare-and-hounds Exercise 1
W. J. Chaplin, T. Appourchaux, T. Arentoft +15
We report on initial results from the first phase of Exercise 1 of the asteroFLAG hare and hounds. The asteroFLAG group is helping to prepare for the asteroseismology component of…
