The Boundary of the Solar Chromosphere

Nature, 1929
THE question of the sudden ending of the chromosphere or its gradual fading away in accordance with Prof. Milne's theoretical views may not yet be settled finally by observation. Mr. R. W. Gurney is, however, under a misapprehension (NATURE, Feb. 16, p. 240) in thinking that the bright K line studied by Mr. P. A. Taylor and Mr. McCrea up to a height of

Dynamics of the solar chromosphere

Astronomy and Astrophysics, 2001
We analyze oscillations in the solar atmosphere using image sequences from the Transition Region and Coronal Explorer (TRACE) in three ultraviolet passbands which sample the upper solar photosphere and low chromosphere.

Solar Wind and Chromospheric Network

Solar Physics, 1997
A physical model of the transition region, including upflow of the plasma in magnetic field funnels that are open to the overlying corona, is presented. A numerical study of the effects of Alfven waves on the heating and acceleration of the nascent solar wind originating in the chromospheric network is carried out within the framework of a two-fluid ...

Understanding the Solar Chromosphere

AIP Conference Proceedings, 2008
We discuss the latest high‐resolution ground and space‐based observations of the solar chromosphere and their relevance to problems of chromospheric modeling. In particular, we briefly review recent as well as previous attempts to understand the solar chromosphere as the atmospheric layer with an apparently increasing temperature.

Solar Chromosphere

2019
This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Physics. Please check back later for the full article. The solar chromosphere (color sphere) is a strongly structured and highly dynamic region (layer) of the Sun’s atmosphere, located above the bright, visible ...

The dynamic solar chromosphere

AIP Conference Proceedings, 2007
With the new ground‐based and space instrumentation observing the solar atmosphere, it is clear nowadays that the quiet sun is of dynamical nature. The Swedish 1m telescope (SST) with its spatial resolution better than 0.2 arc sec. allows us to follow the dynamics of the fine structures observed in photospheric, as well in chromospheric lines.

Solar and stellar chromospheres

2005
This review attempts to highlight two fundamental and complementary aspects of the chromospheric phenomenon; viz., global properties of stellar chromospheres and their variation among the stars, and the underlying fine structure that affects or determines these global properties.

Structure of the Solar Chromosphere

Nature, 1964
THE suggestion of Biermann1 and Schwarzschild2, that the radially increasing temperature of the solar atmosphere is to be ascribed to propagation of non-thermal energy, such as acoustic waves, is now generally accepted. The effect of magnetic field, and the possibility that the energy-carrying waves are of a magnetohydrodynamic character rather than ...

Variability of the solar chromospheric network over the solar cycle

Solar Physics, 1994
From a large sample of the Kodaikanal spectroheliograms in the Call K line we have studied the variations in the intensity of the network elements over two solar cycles and have estimated their contribution to the overall variability seen in the disc-averaged K line profiles.
