The Effect of Abnormal Granulation on Acoustic Wave Travel Times and Mode Frequencies
K. Petrovay, R. Erdelyi, M. J. Thompson
Observations indicate that in plage areas (i.e. in active regions outside sunspots) acoustic waves travel faster than in quiet sun, leading to shortened travel times and higher p-m…

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…
