IRIS NUV diagnostics for Ellerman bombs: spectral properties, thermodynamics, and formation height

I. J. Soler Poquet, C. J. Díaz Baso, A. Sainz Dalda +3

Context. Ellerman bombs (EBs) are observational signatures of small-scale magnetic reconnection, key to understanding the lower solar atmosphere. While their role in active regions…

The connection between solar coronal abundances and the underlying lower atmospheric properties

Paola Testa, Juan Martinez-Sykora, Bart De Pontieu +4

Elemental abundances in the solar corona and solar wind are often observed to differ from those in the solar photosphere, most commonly showing an enhancement of low first ionizati…

Predicting the thermodynamics in the chromosphere from the translation of SDO data into the IRIS inversion results using a visual transformer model

Alberto Sainz Dalda, Vishal Upendran, Juno Kim +4

We present SDO2IRIS: a visual transformer model that translates a combination of images of the chromosphere and transition region (TR), observed by AIA, and a line-of-sight mag…

Bifrost Models of the Quiet Sun. I. Comparison with Solar Observations

Milan Gošić, Viggo H. Hansteen, Alberto Sainz Dalda +2

Studying the emergence of magnetic fields is essential for understanding the physical mechanisms behind various phenomena in the solar atmosphere. Most importantly, the emerging fi…

Global impact of emerging internetwork fields on the low solar atmosphere

Milan Gošić, Bart De Pontieu, Alberto Sainz Dalda

Small-scale, newly emerging internetwork (IN) magnetic fields are considered a viable source of energy and mass for the solar chromosphere and possibly the corona. Multiple studies…
