Is the current lack of solar activity only skin deep?
A. -M. Broomhall, W. J. Chaplin, Y. Elsworth +2
The Sun is a variable star whose magnetic activity and total irradiance vary on a timescale of approximately 11 years. The current activity minimum has attracted considerable inter…
Radius determination of solar-type stars using asteroseismology: What to expect from the Kepler mission
D. Stello, W. J. Chaplin, H. Bruntt +22
For distant stars, as observed by the NASA Kepler satellite, parallax information is currently of fairly low quality and is not complete. This limits the precision with which the a…
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…
A modified peak-bagging technique for fitting low- solar p-modes
S. T. Fletcher, W. J. Chaplin, Y. Elsworth +1
We introduce a modified version of a standard power spectrum `peak-bagging' technique which is designed to gain some of the advantages that fitting the entire low-degree p-mode pow…
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…
solarFLAG hare and hounds: on the extraction of rotational p-mode splittings from seismic, Sun-as-a-star data
W. J. Chaplin, T. Appourchaux, F. Baudin +18
We report on results from the first solar Fitting at Low-Angular degree Group (solar FLAG) hare-and-hounds exercise. The group is concerned with the development of methods for extr…
