An important test of stellar evolution theory is provided by observations of stel- lar clusters, whose members can re

Wilson Observatory. The Dopplergrams were obtained with a Na magneto-optical filter and a 244 x 248-pixel CID camera. From the time series we computed po

An optimal averaging inversion procedure due to Backus & Gilbert (1970) has been applied to frequency splittings measured from power spectra obtained using Doppler data spanning three and five consecutive days. The resulting rotation curves have proven to be much more stable than the c

The data were projected onto both equatorial and polar sectoral modes and Fourier transformed in time. Comparing the resulting power sp
