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…
Evolution of dynamic fibrils from the cooler chromosphere to the hotter corona
Sudip Mandal, Hardi Peter, Lakshmi Pradeep Chitta +17
Dynamic fibrils (DFs) are commonly observed chromospheric features in solar active regions. Recent observations from the Extreme Ultraviolet Imager (EUI) aboard the Solar Orbiter h…
Discovery of Scattering Polarization in the Hydrogen Lyman- Line of the Solar Disk Radiation
R. Kano, J. Trujillo Bueno, A. Winebarger +25
There is a thin transition region (TR) in the solar atmosphere where the temperature rises from 10,000 K in the chromosphere to millions of degrees in the corona. Little is known a…
Long-Period Intensity Pulsations in Coronal Loops Explained by Thermal Non-Equilibrium Cycles
Clara Froment, Frédéric Auchère, Guillaume Aulanier +4
In solar coronal loops, thermal non-equilibrium (TNE) is a phenomenon that can occur when the heating is both highly-stratified and quasi-constant. Unambiguous observational identi…
Thermal non-equilibriuem revealed by periodic pulses of random amplitudes in solar coronal loops
F. Auchère, C. Froment, K. Bocchialini +2
We recently detected variations in extreme ultraviolet intensity in coronal loops repeating with periods of several hours. Models of loops including stratified and quasi-steady hea…
Evidence for evaporation-incomplete condensation cycles in warm solar coronal loops
Clara Froment, Frédéric Auchère, Karine Bocchialini +3
Quasi-constant heating at the footpoints of loops leads to evaporation and condensation cycles of the plasma: thermal non-equilibrium (TNE). This phenomenon is believed to play a r…
Long-period intensity pulsations in the solar corona during activity cycle 23
F. Auchère, K. Bocchialini, J. Solomon +1
We report on the detection (10 σ) of 917 events of long-period (3 to 16 hours) intensity pulsations in the 19.5 nm passband of the SOHO Extreme ultraviolet Imaging Telescope. The d…
On the Accuracy of the Differential Emission Measure Diagnostics of Solar Plasmas. Application to AIA/SDO. Part I: Isothermal plasmas
Chloé Guennou, Frédéric Auchère, Elie Soubrié +2
DEM analysis is a major diagnostic tool for stellar atmospheres. But both its derivation and its interpretation are notably difficult because of random and systematic errors, and t…
On the Accuracy of the Differential Emission Measure Diagnostics of Solar Plasmas. Application to AIA/SDO. Part II: Multithermal plasmas
Chloé Guennou, Frédéric Auchère, Elie Soubrié +2
The Differential Emission Measure (DEM) analysis is one of the most used diagnostic tools for solar and stellar coronae. Being an inverse problem, it has limitations due to the pre…
