Determining global parameters of the oscillations of solar-like stars
S. Mathur, R. A. Garcia, C. Regulo +7
Helioseismology has enabled us to better understand the solar interior, while also allowing us to better constrain solar models. But now is a tremendous epoch for asteroseismology…
A fresh look at the seismic spectrum of HD49933: analysis of 180 days of CoRoT photometry
O. Benomar, F. Baudin, T. L. Campante +18
Solar-like oscillations have now been observed in several stars, thanks to ground-based spectroscopic observations and space-borne photometry. CoRoT, which has been in orbit since…
The quest for the solar g modes
T. Appourchaux, K. Belkacem, A. M. Broomhall +18
Solar gravity modes (or g modes) -- oscillations of the solar interior for which buoyancy acts as the restoring force -- have the potential to provide unprecedented inference on th…
Corrections of Sun-as-a-star p-mode frequencies for effects of the solar cycle
A. -M. Broomhall, W. J. Chaplin, Y. Elsworth +2
Solar p-mode frequencies vary with solar activity. It is important to take this into account when comparing the frequencies observed from epochs that span different regions of the…
Mode lifetimes of stellar oscillations - Implications for asteroseismology
W. J. Chaplin, G. Houdek, C. Karoff +2
Successful inference from asteroseismology relies on at least two things: that the oscillations in the stars have amplitudes large enough to be clearly observable; and that the osc…
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…
