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…
The IRIS inversion tool: recovering the radiative losses and the thermodynamics in the lower solar atmosphere
Alberto Sainz Dalda, Jaime de la Cruz RodrÃguez, Viggo Hansteen +2
We introduce an improved and fast inversion tool that is able to provide the thermodynamics of the solar atmosphere from the photosphere to the top of the chromosphere, as well as…
A sudden fine-scale bright kernel captured by Hi-C Flare in 11 MK emission during an M1.6-class solar flare's post-maximum phase
Sanjiv K. Tiwari, Navdeep K. Panesar, Ronald L. Moore +17
On April 17, 2024, the third successful Hi-C sounding rocket flight, Hi-C Flare, recorded coronal images in Fe XXI 129 A emission from 11 MK plasma during the post-maximum phase of…
Solar Flare Ion Temperatures
Alexander J. B. Russell, Vanessa Polito, Paola Testa +2
This paper proposes that the ion temperature is several times the local electron temperature in the hot onset phase and at the above-the-loop region of solar flares. The paper cons…
Determining the magnetic field of active region plages using the whole CLASP2/2.1 spectral window
David Afonso Delgado, Tanausú del Pino Alemán, Javier Trujillo Bueno +16
The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the ma…
Quantifying Suppression of Solar Surface Magnetic Flux Advection with Increasing Field Strength
V. Aparna, Sanjiv K. Tiwari, Ronald L. Moore +4
One of the main theories for heating of the solar corona is based on the idea that solar convection shuffles and tangles magnetic field lines to make many small-scale current sheet…
