Preferential Appearance of Hα Moreton Waves along Photospheric Magnetic Network Boundaries
The Astrophysical Journal LettersMoreton waves are rare chromospheric signatures of large-scale coronal disturbances, often associated with big flares and coronal mass ejections. Using high-cadence, full-disk H α spectroscopic observations from Chinese H α Solar Explorer, together with ...

Solar wind Acceleration from the Upper Chromosphere to the Corona in Coronal Hole Regions [PDF]
, 1998 The dynamic behavior of the plasma in the chromosphere/transition region /inner corona is vital for the acceleration of the solar wind. With new theoretical descriptions of the solar atmosphere and corona, and the increased observational possibilities ...

Propagation of alfvénic waves from corona to chromosphere and consequences for solar flares
, 2013 How do magnetohydrodynamic waves travel from the fully ionized corona, into and through the underlying partially ionized chromosphere, and what are the consequences for solar flares?

Determining the Magnetic Field of Active Region Plages Using the Whole CLASP2/2.1 Spectral Window
The Astrophysical JournalThe Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the magnetism of the solar chromosphere.

Dynamics of the Quiet Solar Chromosphere [PDF]
, 1999 The solar chromosphere has never been static although it was often modeled so.Even the quiet-sun internetwork chromosphere has become thoroughly dynamic with the acoustic shock interpretation of the Ca II K 2V grains.

The Formation Height of Millimeter-wavelength Emission in the Solar Chromosphere
, 2020 In the past few years, the ALMA radio telescope has become available for solar observations. ALMA diagnostics of the solar atmosphere are of high interest because of the theoretically expected linear relationship between the brightness temperature at ...

LIII. Ionization in the solar chromosphere [PDF]
The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, 1920 1. 1. In the present paper it has been shown from a discussion of the high-level chromospheric spectrum that this region is chiefly composed of ionized atoms of Calcium, Barium, Strontium, Scandium...
