PublicaciónSolar structure from global studies of the 5-minute oscillation
An overall view of the solar surface is presented with emphasis on the study of low 1 value oscillations. Line of sight velocity measurements of the whole solar...

PublicaciónStructure of the 5-minute solar oscillations - 1976-1980
The discrete structure in the 5 min velocity oscillations of the solar surface has been confirmed by a re-analysis of data obtained between 1976 and 1979, and...

PublicaciónTemporal and center-to-limb variations of the K I 769.9 NM line profiles in quiet and active solar regions
The temporal and spatial behaviour of the K I 769.9 nm solar line are investigated using several series of high spectral resolution low-noise photoelectric...

PublicaciónThe 160 minute solar oscillation - an artifact?
Analysis of data obtained over the years 1980-1985 are analyzed to show that the period of the 160-minute signal is indeed 160.00 minutes. It is demonstrated...
