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…
Formation of the helium EUV resonance lines
Thomas Peter Golding, Jorrit Leenaarts, Mats Carlsson
Context: While classical models successfully reproduce intensities of many transition region lines, they predict helium EUV line intensities roughly an order of magnitude lower tha…
Non-LTE inversions of the Mg II h&k and UV triplet lines
Jaime de la Cruz Rodríguez, Jorrit Leenaarts, Andrés Asensio Ramos
The Mg II h&k lines are powerful diagnostics for studying the solar chromosphere. They have become particularly popular with the launch of the IRIS satellite, and a number of studi…
3D NLTE analysis of the most iron-deficient star, SMSS0313-6708
Thomas Nordlander, Anish M. Amarsi, Karin Lind +5
Models of star formation in the early universe depend on the details of accretion, fragmentation and radiative feedback. Different simulations predict different initial mass functi…
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…
Partial redistribution in 3D non-LTE radiative transfer in solar atmosphere models
Andrii V. Sukhorukov, Jorrit Leenaarts
Resonance spectral lines such as H I Ly α, Mg II h&k, and Ca II H&K that form in the solar chromosphere are influenced by the effects of 3D radiative transfer as well as partial re…
