Pseudo-global Fitting of Gapped Helioseismic Data
S. T. Fletcher, W. J. Chaplin, Y. Elsworth +1
Mode fitting or "peak-bagging" is an important procedure in helioseismology allowing one to determine the various mode parameters of solar oscillations. We have recently developed…
The simulation of realistic BiSON-like helioseismic data
S. T. Fletcher, R. New, W. J. Chaplin +1
When simulating full-disc helioseismic data, instrumental noise has traditionally been treated as time-independent. However, in reality, instrumental noise will often vary to some…
SMEI observations of previously unseen pulsation frequencies in gamma Doradus
N. J. Tarrant, W. J. Chaplin, Y. P. Elsworth +2
Aims: As g-mode pulsators, gamma-Doradus-class stars may naively be expected to show a large number of modes. Taking advantage of the long photometric time-series generated by the…
Reliability of P mode event classification using contemporaneous BiSON and GOLF observations
R. Simoniello, W. J. Chaplin, Y. P. Elsworth +1
We carried out a comparison of the signals seen in contemporaneous BiSON and GOLF data sets. Both instruments perform Doppler shift velocity measurements in integrated sunlight, al…
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…
