PublicationRotational splitting of L = 1 P modes
An analysis of the frequency spectrum of the amplitude modulation of specific l = 1 p modes was carried out. A mean rotational splitting value of 0.74 mHz was...

PublicationRotational splitting of low L solar p-mode
Rotational splitting measurements of less than 5 p-modes are calculated using different sources of data. For l=1, data obtained from years 1981 to 1985 is used...

PublicationSecular variations in the spectrum of solar p-modes
The solar p-mode spectrum of very low l is measured with high accuracy for a long enough period of time so as to allow the search for solar cycle variations. In...

PublicationSolar core rotation
Data from solar line of sight velocity measurements are presented to demonstrate the existence of a synodic signal with a 6.5 m/sec amplitude. Recordings of...

PublicationSolar observations: Techniques and interpretation
This book includes four chapters devoted to techniques and interpretation of solar observations. The chapter on high spatial resolution techniques considers...

PublicationSolar oscillations from two widely separated stations
Potassium line data from observatories in Hawaii and Spain were used to establish the authenticity of complex solar oscillation signals. Combination of the two...

PublicationStorage of magnetic flux tubes in a convective overshoot region
Consideration is given to the suppression of the radial and polar escape of magnetic flux in the form of toroidal flux tubes (flux rings) from low latitudes in...

PublicationThe radial velocity of the sun as a star and the solar cycle
Radial velocity measurements of the sun as a star using a resonant scattering spectrometer have been obtained at Izaña (Tenerife) during long observing seasons...
