The Flare Likelihood and Region Eruption Forecasting (FLARECAST) Project: Flare forecasting in the big data & machine learning era
M. K. Georgoulis, D. S. Bloomfield, M. Piana +25
The EU funded the FLARECAST project, that ran from Jan 2015 until Feb 2018. FLARECAST had a R2O focus, and introduced several innovations into the discipline of solar flare forecas…
Differential Emission Measure Evolution as a Precursor of Solar Flares
C. Gontikakis, I. Kontogiannis, M. K. Georgoulis +4
We analyse the temporal evolution of the Differential Emission Measure (DEM) of solar active regions and explore its usage in solar flare prediction. The DEM maps are provided by t…
Testing predictors of eruptivity using parametric flux emergence simulations
Chloé Guennou, Etienne Pariat, Nicole Vilmer +1
Solar flares and coronal mass ejections (CMEs) are among the most energetic events in the solar system, impacting the near-Earth environment. Flare productivity is empirically know…
Energetic characterisation and statistics of solar coronal brightenings
Vincent Joulin, Éric Buchlin, Jacques Solomon +1
To explain the high temperature of the corona, much attention has been paid to the distribution of energy in dissipation events. Indeed, if the event energy distribution is steep e…
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…
Relative Abundance Measurements in Plumes and Interplumes
Chloé Guennou, Michael Hahn, Daniel Wolf Savin
We present measurements of relative elemental abundances in plumes and interplumes. Plumes are bright, narrow structures in coronal holes that extend along open magnetic field line…
Can the Differential Emission Measure constrain the timescale of energy deposition
Chloé Guennou, Frédéric Auchère, James A. Klimchuk +2
In this paper, the ability of the Hinode/EIS instrument to detect radiative signatures of coronal heating is investigated. Recent observational studies of AR cores suggest that bot…
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…
Coronal Temperature Maps from Solar EUV images: a Blind Source Separation Approach
T. Dudok de Wit, S. Moussaoui, C. Guennou +5
Multi-wavelength solar images in the EUV are routinely used for analysing solar features such as coronal holes, filaments, and flares. However, images taken in different bands ofte…
TomograPy: A Fast, Instrument-Independent, Solar Tomography Software
Nicolas Barbey, Chloé Guennou, Frédéric Auchère
Solar tomography has progressed rapidly in recent years thanks to the development of robust algorithms and the availability of more powerful computers. It can today provide crucial…
