Correcting stellar oscillation frequencies for near-surface effects
Hans Kjeldsen, Timothy R. Bedding, Joergen Christensen-Dalsgaard
In helioseismology, there is a well-known offset between observed and computed oscillation frequencies. This offset is known to arise from improper modeling of the near-surface lay…
Detection of Solar-like Oscillations in the G7 Giant Star xi Hya
S. Frandsen, F. Carrier, C. Aerts +9
We report the firm discovery of solar-like oscillations in a giant star. We monitored the star xi Hya (G7III) continuously during one month with the CORALIE spectrograph attached t…
Equation of state and helioseismic inversions
Sarbani Basu, J. Christensen-Dalsgaard
Inversions to determine the squared isothermal sound speed and density within the Sun often use the helium abundance Y as the second parameter. This requires the explicit use of th…
