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…
A framework for describing correlated excitation of solar p modes
W. J. Chaplin, Y. Elsworth, T. Toutain
In a previous paper we suggested that, for a given p mode, the excitation function is the same as the component of the solar background noise that has an identical surface spherica…
Asteroseismology of red giants: photometric observations of Arcturus by SMEI
N. J. Tarrant, W. J. Chaplin, Y. Elsworth +2
We present new results on oscillations of the K1.5 III giant Arcturus (alpha Boo), from analysis of just over 2.5 yr of precise photometric observations made by the Solar Mass Ejec…
Frequency, splitting, linewidth and amplitude estimates of low-l p modes of alpha Cen A: analysis of WIRE photometry
S. T. Fletcher, W. J. Chaplin, Y. Elsworth +2
We present results of fitting the 50-day time series of photometry of alpha Cen A taken by the WIRE satellite in 1999. Both power spectrum and autocovariance function (ACF) fitting…
