Differential rotation: the chromosphere to the quiet chromosphere

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Synoptic maps of Ca II K-normalized intensity at ±40° latitude belt from Carrington rotations 827 (1915 August 10) to 1764 (1985 July 7) are utilized to investigate the long-term variation of the quiet chromospheric differential rotation within solar activity cycles through removing some large values of Ca II-normalized ...

The quiet-Sun photosphere and chromosphere [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2012
Abstract The overall structure and the fine structure of the solar photosphere outside active regions are largely understood, except possibly the important roles of a turbulent near-surface dynamo at its bottom, internal gravity waves at its top and small-scale vorticity. Classical one-dimensional static radiation-escape modelling has

Chromospheric rotation

Solar Physics, 1979
In this paper the dependance of the rotation rate of chromospheric features on their is discussed. The angular velocity of short lived emission features at chromospheric level has been determined by analyzing daily filtergrams in the Ca 11K3 line, obtained at the Anacapri Observatory, in the period 8 May-14August 1972.
