Chromospheric models of a solar flare including velocity fields
(EDP Sciences, 2002-05)
We study the chromospheric structure of a small flare, before, during and after the first hard X-ray spike. We construct 5 semiempirical models for different times, which will reproduce the profiles of the Hδ, Ca II K and ...
Blue lines as chromospheric diagnostics: The Si I lines at 3906 and 4103 Å
(IOP Publishing, 2001-05)
We present a complete atomic model for Si I line synthesis. We study how the computed profiles of two blue lines of this atom are influenced by the choice of the atomic parameters and find that, although several cross ...
A study of a coronal hole associated with a large filament eruption
(2017)
We report the results of a detailed study of an equatorial coronal hole and a dimming region related to the eruptions of a nearby large filament and subsequent coronal mass ejections (CMEs). The dynamic eruptions of the ...
Chromospheric models of solar analogues with different activity levels
(EDP Sciences, 2005-12)
We computed chromospheric models of the Sun as a star and of nine solar analogues. The atmospheric models were constructed to obtain the best possible match with the Ca II K and Hβ lines, including the asymmetry of the ...
Two step mechanism for Moreton wave excitations in a blast-wave scenario: The 2006 December 06 case study
(Wiley Blackwell Publishing, Inc, 2015-10)
We examine the capability of a blast-wave scenario - associated with a coronal flare or to the expansion of CME flanks - to reproduce a chromospheric Moreton phenomenon. We also simulate the Moreton event of 2006 December ...
THE CHROMOSPHERIC SOLAR MILLIMETER-WAVE CAVITY ORIGINATES IN THE TEMPERATURE MINIMUM REGION
(The Astrophysical Journal, 2013)
Are CMEs capable of producing Moreton waves? A case study: The 2006 December 6 event
(Oxford University Press, 2018-02)
Considering the chromosphere and a stratified corona, we examine, by performing 2D compressible magnetohydrodynamics simulations, the capability of a coronal mass ejection (CME) scenario to drive a Moreton wave. We find ...
Comparison Of 30 Thz Impulsive Burst Time Development To Microwaves, H Alpha, Euv, And Goes Soft X-rays

Comparison Of 30 Thz Impulsive Burst Time Development To Microwaves, H Alpha, Euv, And Goes Soft X-rays
(EDP Sciences ASLes Ulis Cedex A, 2016)
The fast and slow H alpha chromospheric responses to non-thermal particles produced during the 1991 March 13 hard X-ray/gamma-ray flare at similar to 08 UTC
