The sun is observed to be a torsional oscillator with a period of 11 years

R. Howard, +1 more
- 01 Jul 1980 - 
TL;DR: A torsional wave pattern with alternating latitude zones of slow and fast rotation is found, after subtracting a differentially rotating frame as mentioned in this paper, which evidently represents a deep-seated circulation pattern and is the first evidence of the association of mass motions with large-scale characteristics of the solar activity cycle.

A method of computing periods of cyclic phenomena

I. Jurkevich
- 01 Sep 1971 - 
TL;DR: In this article, the use of an analysis of Expected Mean Square Deviation to search for periodicities in an observational data sample is described, and the statistic for testing the null hypothesis of non-periodicity is derived from a partitioning of the total sum of squared deviations from the mean.

Periodic behaviour of solar flare activity

Kiyoshi Ichimoto, +4 more
- 01 Aug 1985 - 
TL;DR: In this paper, the temporal variation of the flare activity of the Sun using the data of 8,821 Hα flares which occurred during the period January 1965 to February 1984, and show new evidence for 155-day and 17-month periodicities of the solar activity.

Long period oscillations in solar diameter measurements

Philippe Delache, +2 more
- 01 Oct 1985 - 
TL;DR: In this paper, a Danjon-type visual astrolabe has been used to estimate the solar diameter from the difference between the zenith distances of the solar centres corresponding to the instances of successive limbs crossing the same almucantar.

Neutrinos from the Sun

B Kuchowicz
- 01 Apr 1976 - 
TL;DR: In this paper, the main properties of the neutrino group (nu e, nu mu, nu e, Nu m, nu m, nu n, nu e, nu m, Nu e,nu m, Nu m ) are discussed.
