Evidence for a Transition Region response to penumbral microjets in sunspots
Gregal J. M. Vissers, Luc H. M. Rouppe van der Voort, Mats Carlsson
Penumbral microjets are short-lived, fine-structured and bright jets that are generally observed in chromospheric imaging of the penumbra of sunspots. Here we investigate their pot…
Ellerman bombs at high resolution III. Simultaneous observations with IRIS and SST
Gregal J. M. Vissers, Luc H. M. Rouppe van der Voort, Robert J. Rutten +2
Ellerman bombs are transient brightenings of the extended wings of the solar Balmer lines in emerging active regions. We describe their properties in the ultraviolet lines sampled…
Ellerman bombs at high resolution. IV. Visibility in Na I and Mg I
R. J. Rutten, L. H. M. Rouppe van der Voort, G. J. M. Vissers
Ellerman bombs are transient brightenings of the wings of the solar Balmer lines that mark reconnection in the photosphere. Ellerman noted in 1917 that he did not observe such brig…
The multi-thermal and multi-stranded nature of coronal rain
P. Antolin, G. Vissers, T. M. D. Pereira +2
In this work, we analyse coordinated observations spanning chromospheric, TR and coronal temperatures at very high resolution which reveal essential characteristics of thermally un…
