Evershed, John (Taylor and Francis, 1933)
The general shift of Fraunhofer lines towards the red

Evershed, John (Taylor and Francis, 1914-10)
Heating of the quiet solar chromosphere. 1: Role of the inner network bright points

Kariyappa, R; Sivaraman, K. R; Anandaram, M. N (Springer, 1994-05)

We have analyzed a large number of Ca II H line profiles at the sites of the bright points in the interior of the network using a 35-min-long time sequence of spectra obtained at the Vacuum Tower Telescope (VTT) of the ...
Photometric study of the profiles of the Fraunhofer lines in the solar spectrum: Part 1. MG. b. Group

Paramasiva Rao, Y; Ananthasubrahmanyam, C. K (Calcutta University Press, 1942-06)

The paper consists of the results of the photometric studies carried out by the authors during the last year. After a brief description of the improvements and refine ments perfected in the Direct-Reading Photo-electric ...
Variations in the solar rotation rate derived from Ca(+) K plage areas

Singh, J; Prabhu, T. P (Springer, 1985-11)

Daily calcium plage areas for the period 1951-1981 (which include the solar cycle 19 and 20) have been used to derive the rotation period of the sun at latitude belts 10-15 deg N, 15-20 deg N, 10-15 deg S, and 15-20 deg ...
