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…

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…

A devil in the detail: parameter cross-talk from the solar cycle and estimation of solar p-mode frequencies

W. J. Chaplin, S. J. Jimenez-Reyes, A. Eff-Darwich +2

Frequencies, powers and damping rates of the solar p modes are all observed to vary over the 11-yr solar activity cycle. Here, we show that simultaneous variations of these paramet…

The visibility of low-frequency solar acoustic modes

A. M. Broomhall, W. J. Chaplin, Y. Elsworth +1

We make predictions of the detectability of low-frequency p modes. Estimates of the powers and damping times of these low-frequency modes are found by extrapolating the observed po…
