Spectropolarimetric fluctuations in a sunspot chromosphere [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020 The instrumental advances made in this new era of 4 m class solar telescopes with unmatched spectropolarimetric accuracy and sensitivity will enable the study of chromospheric magnetic fields and their dynamics with unprecedented detail. In this regard, spectropolarimetric diagnostics can provide invaluable insight into magneto-hydrodynamic (MHD) wave ...

The tangential discontinuous surface of velocity in solar chromosphere
, 1991 The data of velocity and magnetic fields in the solar photosphere (5324 angstrom) and the chromosphere (4861 angstrom) clearly show the features of tangential discontinuity of velocity in the chromosphere.

Measuring Magnetic Field With Atacama Large Millimeter/Submillimeter Array
Frontiers in Astronomy and Space Sciences, 2020 The article discusses the use of magnetic bremsstrahlung at short radio wavelengths for measuring solar magnetic fields. The polarization and brightness spectra observed at millimeter wavelengths can be used to deduce the vertical component of the ...

Heating of the solar chromosphere in a sunspot light bridge by electric currents
, 2021 Context. Resistive Ohmic dissipation has been suggested as a mechanism for heating the solar chromosphere, but few studies have established this association. Aims.

THE CHROMOSPHERE-LIKE ENVELOPE OF THE VARIABLE STAR T TAU
Odessa Astronomical Publications, 2017 The emission measure of the near-star chromosphere-like envelope of variable star T Tau with various mechanisms of radiation is computed. The normalization on the observed distribution of energy in continuum spectrum is carried out.

Alfvénic wave heating of the upper chromosphere in flares [PDF]
, 2016 We have developed a numerical model of flare heating due to the dissipation of Alfvénic waves propagating from the corona to the chromosphere. With this model, we present an investigation of the key parameters of these waves on the energy transport ...

Signatures of Magnetic Flux Ropes in the Low Solar Atmosphere Observed in High Resolution
Frontiers in Astronomy and Space Sciences, 2019 Magnetic flux ropes (MFRs) are important physical features closely related to solar eruptive activities with potential space weather consequences. Studying MFRs in the low solar atmosphere can shed light on their origin and subsequent magnetic structural

Turbulence in the Chromosphere
Publications of the Astronomical Society of Japan, 1962 Abstract Turbulence velocities in the chromosphere were determined from the base up to 10,000 km. Measurement was made on flash spectrograms of 1958 eclipse in South Pacific. The dispersion was about 2.3 A/mm and the resolution in terms of velocity was 2–3 km/sec in most probable velocity ξ0.
