Observations of Ellerman bomb emission features in He I D3 and He I 10830 Å
Tine Libbrecht, Jayant Joshi, Jaime de la Cruz Rodríguez +2
Context. Ellerman bombs (EBs) are short-lived emission features, characterized by extended wing emission in hydrogen Balmer lines. Until now, no distinct signature of EBs has been…
Vertical magnetic field gradient in the photospheric layers of sunspots
Jayant Joshi, Andreas Lagg, Johann Hirzberger +2
We investigate the vertical gradient of the magnetic field of sunspots in the photospheric layer. Independent observations were obtained with the SOT/SP onboard the Hinode spacecra…
Upper Chromospheric Magnetic Field of a Sunspot Penumbra: Observations of Fine Structure
J. Joshi, A. Lagg, S. K. Solanki +22
The fine-structure of magnetic field of a sunspot penumbra in the upper chromosphere is to be explored and compared to that in the photosphere. High spatial resolution spectropolar…
The cause of spatial structure in solar He I 1083 nm multiplet images
Jorrit Leenaarts, Thomas Golding, Mats Carlsson +2
Context. The He i 1083 nm is a powerful diagnostic for inferring properties of the upper solar chromosphere, in particular for the magnetic field. The basic formation of the line i…
