Effects of line asymmetries on the determination of solar internal structure
M. C. Rabello-Soares, J. Christensen-Dalsgaard, C. S. Rosenthal +1
Despite the strong evidence that the peaks in the spectrum of solar oscillations are asymmetric, most determinations of mode frequencies have been based on fits of symmetric Lorent…
Test of Convective Frequency Effects with SOI/MDI High-Degree Data
C. S. Rosenthal, J. Christensen-Dalsgaard, A. G. Kosovichev +6
Advances in hydrodynamical simulations have provided new insights into the effects of convection on the frequencies of solar oscillations. As more accurate observations become avai…
P-mode Line-Shapes in Theory and Practice
C. S. Rosenthal
The asymmetries of solar p-mode lines provide important diagnostic clues as to the nature and location of the source of mode excitation. At the same time, they can also be responsi…
Convective contributions to the frequencies of solar oscillations
C. S. Rosenthal, J. Christensen-Dalsgaard, A. Nordlund +2
Differences between observed and theoretical eigenfrequencies of the Sun have characteristics which identify them as arising predominantly from properties of the oscillations in th…
NEAR-SURFACE EFFECTS IN MODELLING OSCILLATIONS OF ETA BOO
J. Christensen-Dalsgaard, T. R. Bedding, G. Houdek +5
Following the report of solar-like oscillations in the G0 V star eta Boo (Kjeldsen et al. 1995, AJ 109, 1313), a first attempt to model the observed frequencies was made by Christe…
