On the Nature of Nonthermal Broadening of Spectral Lines Observed by IRIS
Kyuhyoun Cho, Bart De Pontieu, Paola Testa
The origin of nonthermal broadening in solar spectra is one of the long-standing questions in solar physics. Various processes have been invoked - including unresolved flows, waves…
A model of umbral oscillations inherited from subphotospheric fast-body modes
Juhyung Kang, Jongchul Chae, Kyuhyoun Cho +2
Recently, complex horizontal patterns of umbral oscillations have been reported, but their physical nature and origin are still not fully understood. Here we show that the two-dime…
Large-amplitude transverse MHD waves prevailing in the H chromosphere of a solar quiet region revealed by MiHI integrated field spectral observations
Jongchul Chae, Michiel van Noort, Maria S. Madjarska +3
The investigation of plasma motions in the solar chromosphere is crucial for understanding the transport of mechanical energy from the interior of the Sun to the outer atmosphere a…
